Stereo Vision
We have developed and demonstrated fast real-time
restoration of 3-D topography based on stereo imaging.
The major innovation is in feature identification using
texture, shading, correlation, and fast algorithms.
3-D reconstruction from a pair of overlapping images requires
identification of features in both images. This identification
can be manual or automated, but automated feature extraction
is difficult and time consuming. CRS has developed an
extremely fast algorithm based on texture, shading, and
correlation. This allows complete topographic restoration
of every pixel in real time. Ordinary digital or video
cameras can acquire the images and the user can access
3-D topography immediately. A demonstration program "XVIEW"
is available. The program can also perform risk analysis
and safe-trajectory estimation for a moving robot.
