About This Page
This page provides information about integration of 3D Slicer and OpenCV. OpenCV is a library of programming functions for real time computer vision. The primary goal of 3D Slicer-OpenCV integration is to provide functionalities to import and process video images used in the medical field e.g. ultrasound and endoscopic video images in 3D Slicer.
How to build 3D Slicer with OpenCV library
Currently (Nov 2010), 3D Slicer 3.6 in trunk repository (http://svn.slicer.org/Slicer3/trunk) is the only version that can be compiled with OpenCV. Please download the source code from the repository, open slicer_variables.tcl and change the following line (around line 190)
set ::USE_OPENCV "OFF"
to
set ::USE_OPENCV "ON"
then, follow "Building the latest development version" in Build Instruction Page.
Example 3D Slicer modules
A good example of application is image overlay system, which projects 3D organ model onto endoscopic video image. There are three experimental module with different approaches are available:
Secondary Window with OpenCV module (Nagoya Institute of Technology)
This module creates a new window with a VTK renderer independent from 3D Slicer's scene. The module copies all VTK models from the MRML scene to its own VTK scene and overlays them on to a video image imported by using OpenCV. The merit of this approach is that the developers can change any properties of models, cameras etc. without modifying any objects in MRML scene. |
StereoCalib module (Nagoya Institute of Technology)
This module is for camera calibration not only single camera but also stereo camera. The output files are the camera intrinsic parameter matrix and the camera distortion compensation vector for Secondary Window with OpenCV module. |
Video Importer module (BWH)
This is a simple demo module of an image overlay. This module copies the video frame into the background of 3D viewer in 3D Slicer and displays 3D models in front of video image. Since the video image is directly imported into the 3D viewer in 3D Slicer, all properties of VTK models in the MRML scene are reflected in the overlaid image. |
The code is available in: http://svn.na-mic.org/NAMICSandBox/trunk/IGTLoadableModules/VideoImporter/
