ICL 6.10.0 Released

Added by Christof Elbrechter over 7 years ago

New General Features

  • added Box-Plots upport to the PlotWidget
  • applied some major changes to the default image visualization widget
  • added fullscreen mode for single widget and an extra blue button for fullscreen (F11 works as well)
  • added tooltips to the tiny blue widget buttons
  • added tooltip to GUI compoenents (use @tooltip=text in your GUI definition)
  • improved Kinect RGBD-Calibration tools
  • replaced (wrong) homography based RGBD mapping with a more sophisticated projective geometry based mapping
  • the new mapping works very well and seems to be comparable to the (unknown) open-NI RGBD-calibration method
  • added performance optimizations (point-cloud creation + rgbd mappings takes less then 5ms)
  • added a new SceneObject class called RGBDImageSceneObject (which will later use the already existent PointcloudSceneObject internally, but it will provide a much simpler and configurable interface)
  • added triangle based rendering to the RGBDImageSceneObject class (quite slow still)
  • added depthmap smoothing for better RGBD mapping
  • added automatic IR-image shift to the Kinect grabber (which compensates for the hardware offset)
  • added a new tool called icl-configurable-info, which can be used to list and inspect the properties of all classes that implement the Configurable-interface
  • added a generic RANSAC implementation + demo-application for shape fitting
  • moved ICLCore/Random.h to ICLUtils/Random.h
  • added generic framework for direct least square model fitting (which was actually part of ICL some year ago in the ICLMEx package)
  • extended the Scene's offscreen rendering method, so that it can also render the depth-buffer to simulate Kinect data
  • added trylock to the Thread and Mutex class
  • PylonGrabber based GIG-E camera support
  • merged the development branch back to the trunk
  • several optimizations and fixes
  • added support for all image depth in the LocalThresholdOp class

Important Changes to the Build System

  • added (still experimental) support for building .deb packages using CMake /CPack
  • try by using the debian-package.cfg configuration script. In the resulting build/debian-package/ directory, you can type 'cpack -G DEB' to create a debian package)
  • completly re-implemented the dependeny tracking CMake code
  • applied several fixes for linux-kernel 3.x support
  • compiled ICL (with most dependencies) under Ubuntu 12.04 (beta1)
  • in particular fixed the missing reference to pthread_atfork by finding out, that Intel IPP 6.1's libiomp is not compatible to the newest glibc. Instead, we now just suggest to use libiomp5.so from Intel IPP 7.0 (update 6) the new version of libiomp5 is already placed in our /vol/nivision/share/IPP/6.1/sharedlib directory

New Functions and Small Changes

  • added SceneObject::clearAllPrimitives function

ICL 5.18.0 released

Added by Christof Elbrechter over 8 years ago

Additional Features and Improvements

  • Adapted the SmartPtr and SmartArray classes to allow for better behavior with inherited types
  • Added new undistortion handling, by now providing not only the simple undistortion model that was suggested by the ARToolkit guys, but also the much more sophisticated Matlab camera calibration toolkit model

    also provide a ./configure script that can be set up with a very simple configuration file
  • the former helper script scripts/icl-cmake.sh was renamed and is deprecated now
  • Added several improvements to the KinectGrabber class
  • Added an extra script called scripts/config-generator.sh that creates build-directories for several common dependency configurations (all dependencies, no dependencies, all except each dependency and each dependency alone)
  • Added new Configurable property type called 'flag'. Flags represent boolean values and are translated to checkboxes in the Configurable-GUI component
  • Added native support for writing and loading png-images even without ImageMagick
    based on libpng.so and png.h (therefore libpng became a new optional dependency)
  • added the global extract_euler_angle function to FixedMatrix.h that allows to extract
    euler angles from a given NxM rotation matrix (N>2 and M>2)

Bugfixes

ICL 5.17.0 release

Added by Christof Elbrechter over 8 years ago

The new version of ICL provides the following features and bug fixes:

New Features
  • Added extra makefile variable ARCHITECTURE_DEPENDENT_BUILD. The build uses g++'s '-march=native' only if this is explicitly set to TRUE

  • acquireImage does no longer have to care about desired parameters -> it only creates a new image
  • the Grabber's grab()-method does now care automatically for using desired parameters
  • The user can also choose to use only one or two of the desired parameters rather than

all or none of them

  • desired parameters are now set using template methods (T can be depth, format and Size)
  • void useDesired<T>(const T&)
  • void ignoreDesired<T>()
  • T getDesired<T>() const

  • some OSX-build related fixes

ICL 5.16.0 released

Added by Christof Elbrechter over 8 years ago

The new version of ICL provides the following features and bug fixes:

Features:
  • New class called Hit that represents Intersections between SceneObjects and ViewRays
  • Optimized scene- object picking including methods to get all objects that are intersected by a given view ray
  • New method to render use an ICL-image as OpenGL texture, that is put on a quad

  • added basic Mac-OSX Support
  • minor improvements in icl-pipe
  • extened ICLGeom's Scene and SceneObject class in order to provide a scene graph implementation
  • applied some major improvements to the camera calibration tool icl-cam-calib (cameras can now be calibrated without a calibration object by manually associating world coordinates to image points

ICL 5.12.0 released (101 comments)

Added by Christof Elbrechter over 8 years ago

Version 5.11.0 was a frequently changed developmental version. The new stable version is 5.12.0.

The new version of ICL comes up with the following new features:
  • Added a Function<..>-template that will be integrated as common callback type. The function template can wrap global functions as well as member functions.
  • Extended the ICLGeom:ViewRay class (which now provides methods to compute distances to 3D-points and other ViewRays).
  • added very basic support templates sqr -> power of two and power<exponent>
  • Fundamentally improved ICL's camera calibration tool icl-cam-calib
  • simplified GUI
  • cleaned up interface
  • modularized implementation (added extra classes CalibrationObject and CalibrationGrid)
  • added manual mode that can be used to define the reference points using mouse
  • added a quite useful utility class that implements the default mouse event handler. The DefineRectanglesMouseHandler can be used to define a set of rectangles (e.g. an image ROI) as an image overlay
  • Added an implementation of the ICP (Iterative Closest Point) Algorithm
  • Added an implementation of KD-Trees (used in ICP, but also available as utility class that is integrated with ICL's DynMatrix class)
  • Updated the way camera-instances are visualized in Scenes (we now use a more or less schematic view that visualizes a part of the cameras view frustum)
  • Added a new utility class called icl::Any. Instances of this class can be created from everything, and they can be casted to anything
  • added a very useful method to the Grabber::interface that provides a mechanism to automatically adapt result images
  • Added support for ICL's Kinect Device. The color camera can be accessed by using the GenericGrabber parameters 'kinectc DEVICE_ID' the depth cameras with 'kinectd DEVICE_ID'.
  • Replaced ICL's selfmade XML-parser by a pugi-XML-based version
  • Added PseudoColorConverter class to the ICLCC package
  • Added global utility-functions openFileDialog and closeFileDialog to the ICLQuick header (of course this is only available with Qt-Support)
  • Added an interface to set a cameras near-clipping plane to values even shorter than the Cameras focal length
  • Optimized ICL's ICLProject makefile system (note: you can create an ICL-Project makefile tree using icl-create-project ProjectName)
  • added install lists for targets that have to be installed to bin and etc
  • enabled local linking for the development tree and global linking for the installed version. By this means, you'll no longer have to call 'make installlink' before you can run your local applications'
  • Added a GUI compoment called "color()" color compoments can be used to define a color at runtime internally using a pop-uped QColorDialog instance
  • Added a new and very powerful interface called Configurable. Configurable instances have a string-based interface for internal properties that allows for automatic creation of corresponding GUI-components.
  • A Configurables GUI can be embedded using the new "prop(..)"-GUI-component
Bug-fixes
  • fixed icl-pipe that could not be build without Qt before
  • fixed some build-issues with OpenCV

    choose a color at runtime
  • new lookup-table function 'lut' was directly integrated into the Img<T>
    template class

    is called with the --update option
  • further minor fixes

ICL 5.9.0 released

Added by Christof Elbrechter almost 9 years ago
