Please note that your license terms impose various restrictions on distribution of ARToolKit in both source and binary forms. Legal remedy will be sought by ARToolworks, Inc. for any unauthorised distribution. Your license terms may entitle you to hot fixes and / or upgrades to ARToolKit Professional version 4.5.3. Please contact us for more information. ARToolKit Professional is designed to build on Linux, Windows, Macintosh OS X, and SGI Irix platforms. This archive was assembled by: Philip Lamb ARToolworks, Inc. http://www.artoolworks.com 2011-05-05 Installing ARToolKit Pro. ----------------------- If you are reading this document from inside an installer, or been supplied with pre-built ARToolKit 4 binaries, you may skip this section. However, it is useful to build ARToolKit 4 to change various options and to add your own customisations, so be sure to attempt it some time. The instructions below are a brief introduction. The most up-to-date build instructions can always be found in the ARToolworks support library at http://www.artoolworks.com/support/library/Installing_ARToolKit_Professional. *** Required software/source packages * A compiler. * Windows: Microsoft Visual Studio 2010, Microsoft Visual Studio 2008 SP1, and Visual Studio 2005 SP1 are supported. The free Microsoft Visual Studio Express Edition will also work. * Mac OS X: Xcode tools v3.1 under Mac OS X 10.5 or later is required. These may be obtained free from Apple at http://developer.apple.com/xcode/. * Linux: GCC 4.4 is recommended. * OpenGL * GLUT; required to build libARgsub and the utilities and examples. (libARgsub_lite provides equivalent functionality to libARgsub without requiring GLUT). * Windows: GLUT 3.7.6 is included with ARToolKit. * Mac OS X: included in OS. * Linux: GLUT should be available in your distribution (e.g. packages freeglut3-dev and xorg-dev). Otherwise, GLUT is included in the MESA 3D libraries: [http://mesa3d.sourceforge.net/] * OpenCV; required to build calib_camera. * Windows: http://downloads.sourceforge.net/opencvlibrary/OpenCV_1.0.exe * Mac OS X: Mark Asbach has created OpenCV binaries for Macintosh in the form of a Private Framework, and this is the OpenCV variant supported by ARToolKit Professional. Click here to download Mark Asbach's OpenCV binary for Macintosh. Once downloaded, create a folder inside your ARToolKit folder named "Frameworks" and drag OpenCV.framework into it. * Linux: http://downloads.sourceforge.net/opencvlibrary/opencv-1.0.0.tar.gz * A video capture source * Windows: By default, on Windows ARToolKit Professional's video library (libARvideo) uses Microsoft's DirectShow as a video source. Unfortunately, this requires installation of the DirectX SDK and either the Windows SDK or the DirectShow package from the Microsoft Platform SDK to compile libARvideo. Please see the separate page Building libARvideo using DirectShow. Alternative video sources on Windows include: * QuickTime, either using the VideoDigitizer or movie files or streams. Please see the separate page Building libARvideo using QuickTime. * Thomas Pintaric's DSVideoLib [http://sourceforge.net/projects/dsvideolib] which is the default video source for ARToolKit v2.x (N.B.: DSVideoLib is now LGPL licensed and may be used in proprietary software.) * Point Grey's flycapture SDK (only for use with Point Grey Cameras). * Canon's HDCam64 camera control library (Canon HDCam64 users only). * Mac OS X: QuickTime v6.4 or later is required, and is included in all versions of Mac OS X > 10.3. * Linux: Video4Linux, lib1394dc, or GStreamer is required. The corresponding packages required to be installed in your package manager are "libv4l2-dev", "libdc1394-22-dev" (for lib1394 version 2.x) or "libdc1394-13-dev" (for lib1394 version 1.x), and "libgstreamer0.10-dev". * OpenVRML (optional); The ARToolKit VRML renderer requires OpenVRML. * Windows: OpenVRML-0.16.6 or later (for Visual Studio 2005) must be on the include and library path to rebuild ARvrml.lib. Suitable binaries of OpenVRML for Windows can be downloaded from http://www.artoolworks.com/dist/openvrml/. * Mac OS X: OpenVRML should be installed using the [http://www.finkproject.org/ Fink] packagemanager. Once fink is installed, the required command to install OpenVRML is <code>fink -b install openvrml6-dev openvrml-gl6-dev</code>. Alternately, a Universal binary build of OpenVRML-0.16.6 suitable for inclusion in application bundles can be downloaded from http://www.artoolworks.com/dist/openvrml/. * Linux: Binary deb packages are available from http://www.openvrml.org/. * OpenSceneGraph (optional); The ARToolKit OSG renderer requires OpenSceneGraph. OSG version 2.6 or later is required, version 2.8.2 is recommended. * Windows / Mac OS X: ARToolworks supplies binaries of OSG at http://www.artoolworks.com/dist/openscenegraph/. ARToolKit uses the environment variable OSG_ROOT to find your OpenSceneGraph installation. * Linux: OpenSceneGraph is available as a package for most Linux distributions (e.g. package libopenscenegraph-dev). *** Building ARToolKit Professional: Windows * After unpacking ARToolKit, run the configure-win32 script. This generates AR/config.h for Windows builds. If you wish to change the default video library, or enable or disable some of the video modules, edit the file include/AR/config.h. See the additional help pages Building libARvideo using DirectShow and Building libARvideo using QuickTime for more help. * Open the ARToolKit4.sln file inside the appropriate directory in side the "VisualStudio" directory. * Build the ToolKit and the sample applications. The VRML and OSG renderers are not built by default, but can be manually selected and built. Mac OS X * Open the ARToolKit4.xcodeproj, found inside the Xcode folder. * The configure step (which creates AR/config.h) will be run automatically during the build process. If you wish to override the defaults, you may manually edit AR/config.h after this. * Select a target to build. The default target builds the complete toolkit with the exception of the OpenVRML and OSG-dependent projects, which can be manually selected and built. Linux * Building proceeds with the usual steps ./configure; make During the configure process, you will be asked to select video libraries to build against. *** Running the simpleLite example: ARToolKit Professional includes a variety of examples demonstrating ARToolKit programming techniques. After compiling, the executables for these applications can be found in the bin directory inside your ARToolKit directory. The simpleLite example is the most straightforward example. It can be run to test your ARToolKit installation is functioning correctly. An explanation of the sourcecode of this example can be found on the page ARToolKit tutorial 1: First simple ARToolKit scene. More detailed information about the techniques demonstrated in each example can be found on the page ARToolKit Professional examples. Windows: simpleLite can be opened by double-clicking its icon in the ARToolKit4\bin directory. Alternately, you can run it from the command line: * Open a command-line window (cmd.exe). * Navigate to your ARToolKit4\bin directory. * Type: simpleLite.exe Mac OS X: Bundled applications are generated for the examples. The utilities are generated as command-line tools. Both can be run in the Finder (with output in Console) or from within Xcode or a Terminal window. Linux: simpleLite can be launched from a terminal window thus: ./simpleLite Changes in version 4.5.3 (this release) (2011-05-05). ----------------------------------------------------- New features: - An online 2D barcode marker generator is available now at http://www.artoolworks.com/support/app/marker.php. Enhancements: - The 4x4 barcode marker set, and two new error-checking and correction codes can now be selected at runtime. - check_id now has command-line switches to control parameters of the markers being used. Bug fixes: - A bug that prevented use of variable-border size markers has been fixed. Changes in version 4.5.2 (2011-04-20). -------------------------------------- Enhancements: - arOSG now allows lighting to be turned on or off per model in the model .dat files. Also, it now allows for setting of viewpoints with the origin left or below (0,0). - A programmatic interface to the QuickTime movie interface is now exposed as <AR/sys/videoQuickTimeMovie.h>. The QuickTime "movie" object can be retreieved via a new function call ar2VideoGetMovieQuickTime(). - A number of iOS-specific code improvements are documented in the iOS release notes. Bug fixes: - ar2VideoGetParams now correctly accepts a pointer to a string for the returned string parameter. - arOSG now turns off all ambient lighting. - The examples now create a window the same size as the incoming camera frame. Previously, a hard-coded window size was used. - A number of iOS-specific bug fixes are documented in the iOS release notes. Changes in version 4.5.1 (2011-03-18). -------------------------------------- Enhancements: - The arOSG library has added support for intersection queries, plus enabling/disabling lighting. Also, much more state information can now be queried. Bug fixes: - Mac OS X: An error which occured when closing the video stream has been corrected. - Mac OS X: The QuickTime7 video module will now default to supplying 32-bit BGRA pixels on Intel architectures and 32-bit ARGB pixels on ppc architectures. This can be overridden (e.g. to supply 2vuy or yuvs-format pixels) using the video config string. Changes in version 4.5.0 (2011-01-24). -------------------------------------- New features: - arFilterTransMat functions to provide pose-estimate filtering. - Support for Microsoft Visual Studio 2010. - mk_patt can now train markers with non-standard border widths. The command line switch "-border=n" (n between 0 and 0.5 (not inclusive)) specifies the desired border width as a proportion of the marker width. The portion of the marker which will be used as the pattern is now indicated by mk_patt by outlining in blue. Note that in order to use markers with non-standard border widths, the border width must be specified in the application by using the arSetBorderSize() function (see reference documentation for more information.) Other changes: - Support for Microsoft Visual Studio 2010 has been added. Changes in version 4.5.0d3 (2011-01-06). ---------------------------------------- New features: - New QuickTime7 video input module for Mac, using the new QTKit Capture APIs. It is now the default video input module on the Mac. This new module offers a dramatic improvement in capture speed from high-definition video sources. If desired, ARToolKit can now be built with Mac OS X 10.6 the minimum version supported. - New example simpleMovie, demonstrating use of the QuickTime video input module to show a video file on a marker. - New utility, check_id, which allows low-level debugging of multi-marker tracking, particularly barcode marker tracking. See http://www.artoolworks.com/support/library/Debugging_marker_recognition_problems for a tutorial. Other changes: - Support for Microsoft Visual Studio .NET 2003, and OpenVRML 0.14.3 have been dropped. Changes in version 4.5.0d2 (2010-11-22). ---------------------------------------- New features: - Variable marker border width. See documentation for arSetBorderSize()/arGetBorderSize(). - Error detection and correction codes with 3x3 matrix markers. Two modes are available, one using parity, and allowing for detection of single-bit errors with up to 32 markers, and one using a Hamming (6,3) code, allowing for detection of up to 3 bit errors and correction of up to 2 bit errors with up to 8 markers. Marker patterns for these modes can be found in the doc/patterns directory. - For identified square regions, which ultimately are not judged by ARToolKit to be known patterns, support is now included for discovering which stage of marker matching cutoff occured. See the documentation for the cutoffPhase member of the ARMarkerInfo structure. Enhancements: - On Mac OS X, adaptive thresholding makes use of the Accelerate framework for improved performance. Changes in version 4.5.0d1 (2010-10-05). ---------------------------------------- New features: - Adaptive thresholding. This algorithm adjusts the threshold intra-frame, and thus should help ARToolKit find markers when lighting condtions are non-uniform across a frame. Adaptive thresholding requires a fast computer, and is not enabled by default. The processing time taken is proportional to the number of pixels in the image; using an 800x600 image size or smaller is recommended. It can be enabled by calling arSetLabelingThreshMode(arHandle, AR_LABELING_THRESH_MODE_AUTO_ADAPTIVE); Manually changing the threshold will disable adaptive thresholding. The kernel size (AR_LABELING_THRESH_ADAPTIVE_KERNEL_SIZE_DEFAULT) must be an odd number, and can be changed at compile-time. Larger values will provide better thresholding but require a faster CPU. Known issues in this release. ----------------------------- - SGI video input is missing. Changes in earlier releases. ---------------------------- Please see the file ChangeLog.txt. -- EOF </pre> == ChangeLog == <pre> ARToolKit Professional ChangeLog. ================================= Changes in version 4.5.4 (this release) (2011-xx-xx). ----------------------------------------------------- Enhancements - Extended controls and modes for ARvideo 1394dc.

Changes in version 4.4.3 (2010-08-20). -------------------------------------- New features: - Added arVideoSaveImageJPEG() funtion, which saves video frame to a jpeg file. - Added a new auto threshold algorithm, based on Otsu's method, and changed this to the default method. Otsu's method typically selects a better threshold than the median, particularly when one or more markers are close to the camera. Enhancements: - Add new config token AR_ENABLE_MINIMIZE_MEMORY_FOOTPRINT. Enabled by default on iPhone, it removes support for the debug image, and saves several hundred KB of memory. Bug fixes: - Extraneous debug output from the pose estimator (ICP) now only present in debug builds, and goes to stderr. - Fix for small memory leak in arVideo. Changes in version 4.4.2 (this release) (2010-03-16). ----------------------------------------------------- New features: - Auto-thresholding. ARToolKit will now by default automatically adjust the binarization threshold to the median image brightness. The brightness is measured using a full-image histogram, which runs by default every 8 frames. Note that if your ARToolKit application manually sets the threshold at any time (including during initialization) the auto-thresholding will be disabled. - New OpenSceneGraph-based rendering library, arOSG. arOSG is intended to provide access to the modern plugin-based scene graph OpenSceneGraph, and its attendant model formats and graphical capabilities. An example and full API documentation is included. Enhancements: - Windows binaries of ARToolKit are now supplied with win64-x64 versions of ARICP. win32-i386 versions now also build to subfolder of lib. - Update Windows DragonFly video module for latest FlyCapture SDK release (changes submitted by Henry Chu). - Reduced contrast required to identify barcode patterns (changed AR_PATT_CONTRAST_THRESH2 in arConfig.h to 15.0). This should enhance detection of barcode patterns. Bug fixes: - Fixup of handling of path separators on Win32 in utility functions to support osgART Professional Editon v1.1.3 ARToolKit4 and ARToolKit4NFT tracker plugins. Changes in version 4.4.1 (2009-09-15). -------------------------------------- Bug fixes: - Moved some symbols from libARvideo to libAR to avoid requirement to co-link. Changes in version 4.4.0 (2009-07-16). -------------------------------------- New features: - Add line matching to pose estimator. - ARG: added "flipmode" for horizontal and vertical flipping. Enhancements: - Mac can also now use video1394dc. - New version of video1394dc, with headers and source, and configuration items. - Add draw square to ARG. - Add video pixel format name utility function. Bug fixes: - AR_AREA_MAX changed from 1e5 to 1e6. Tracking will now function better with HD images when marker is close to the camera. - Bug fixes in video1394dc. - Robust ppose estimator now makes better probability estimates. - Removal of 'static' qualifiers in multi lib. - Remove erroneous default video config in mk_patt for Windows DirectShow video. - Syntax error fixed in arViewerCapi.cpp. - Fix bug in videoQuickTime when UVC driver incorrectly reports frame timing. - Correct potential error in marker detection loop in examples. - Fix bug whereby request for a non-default pixel format was ignored by gsub_lite. - Change internal lib linkage in Xcode. - Removed some debug output from ARICP library. Changes in version 4.3.4 (2008-11-11). -------------------------------------- Enhancements: - Add support for 3 packed pixel formats (RGB565, RGBA5551 and RGBA4444). - Addition of asynchronous fetching of video frames. New function ar2VideoGetImageAsync. At present, implemented only in dummy video. - Support for requesting power-of-2 sized buffers (via config string "-bufferpow2") from dummy video lib. - Replaced all double-precision floating point declarations with a macro which can be redefined to single-precision floating point as an optimisation. - Add 4x3 and 8x6 multi patterns and PDFs and Letter-size multi PDF. - Change multi-marker loading to allow backwards compatibility with config files from ARToolKit v2.x. Bug fixes: - Some gstreamer fixes incorporated, including correct pre-rolling with some additional source types, correction of default video config, and compatibility with new gstreamer releases. - Fixes to dual-mode marker detection (two pass detection of both matrix and template markers). arSetPatternDetectionMode no longer incorrectly rejects two-pass modes as invalid. - Debug image alpha channel (where appropriate) is now set to opaque. - More headerDoc documentation added. Changes in version 4.3.3 (2008-02-18). -------------------------------------- New features: - Scripts to set and unset the ARTOOLKIT_4_ROOT environment variable have been added for the Linux and Mac OS X platforms. See the "share" directory. - A script "share/artoolkit4-config" allows 3rd-party applications to query ARToolKit build settings on the Linux and Mac OS X platforms. Bug fixes: - ARToolKit now assumes a little-endian architecture on Linux if the __BIG_ENDIAN__ macro is not defined by the preprocessor. - Change in multi-marker pattern file format (arMultiReadConfigFile); pattern filenames in a multimarker config file are now relative to the config file, rather than the working directory. Changes in version 4.3.2 (2008-01-20). -------------------------------------- New features: - A new example, multiCube, demonstrates the use of non-planar multimarker sets, in this case a cube. Sample PDFs for cube markers are in doc/patterns/Cubes. - Add VideoGStreamer (LGPL license) which uses the GStreamer library for video input. Copyright Hartmut Seichter and ARToolworks, Inc. Enhancements: - The environment variable ARTOOLKIT_4_CONFIG can now be used to globally set the video configuration to be used when none is specified in the call to ar(2)VideoOpen(). Bug fixes: - Configuration of Makefile builds (Linux, and optionally Mac OS X) has been cleaned up. - "-device=" option can now safely be passed to video input modules which don't use "-option" syntax. - gsub_lite is now correctly built in Makefile builds. Changes in version 4.3.1 (2008-01-08). -------------------------------------- Other changes: - Update Xcode project for Xcode 3.0 compatibility. - Add arVideoUtilGetPixelFormat to libARvideo (duplicate of libAR's arUtilGetPixelFormat) to allow independent linkage. Changes in version 4.3 (2007-10-31). ------------------------------------ New features: - Hirokazu Kato has rewritten his original fast pose estimator a modern algorithm. The new pose estimator offers comparable accuraccy, with much improved speed. - A robust pose estimator has been added. See the documentation for functions arGetTransMatRobust() and arGetTransMatStereoRobust(). These functions are also available under multi-marker tracking. - Examples for multi-marker tracking and stereo tracking added. - Video input via QuickTime from file and streaming video sources has been added on Mac OS X and Windows. Full documentation is available in the ARToolworks support library. - A set of utilities for Linux 1394dc video have been added: whitebalance, checkimage, listcamera. Enhancements: - Camera calibration is now performed using the OpenCV library and is greatly simplified. A new version 4 of the camera calibration parameters is now saved. Camera calibration files generated with the earlier (versions 1 through 3) of the camera calibration utility may still be used. The old camera calibration utility is available as calib_camera_old-v3. - Multi-marker tracking is now available in two modes, template (pictorial markers) and matrix (2D-barcode markers). These modes can be used exclusively or together in a two-pass arrangement. - Some convenience functions added to gsub library: argGetScreenSize(), argSetWindowSize(). - Video parameters under the Linux 1394dc video library can now be saved and restored. - ARvrml, the VRML renderer, now supports openvrml-0.16.6 on all platforms, and builds as a DLL on Windows to ease Building of programs that use ARvrml. Bug fixes: - arUtilSleep() now correctly operates in milliseconds on Unix-based systems. Other changes: - Minor changes in the parameters to some functions: please check the documentation for more information: arGetDebugMode(), arGetLabelingMode(), arGetLabelingThresh(), arGetImageProcMode(), arGetPattDetectionMode(), arGetMarkerExtractionMode(), arGetTransMat(), arGetTransMatStereo(), argGenImageTexture(). - The following functions have been removed: arGetTransMatSub(), arGetTransMatSubStereo(), arModifyMatrix(), arModifyMatrixStereo(), arGetAngle(), arGetRot(), arGetNewMatrix(), arGetInitRot().
