Stereo Matching

A GUI demonstrates an efficient stereo matching algorithm.

FAST MATLAB STEREO MATCHING ALGORITHM (SAD)

This function performs the computationally expensive step of matching two rectified and undistorted stereo images. The output is a dense disparity map. If camera parameters are known, this allows for three dimensional reconstruction.

Two graphical user interfaces demonstrate the algorithm.

Please note this function requires the Image Processing Toolbox!

[spdmap, dcost, pcost, wcost] = stereomatch(imgleft, imgright, windowsize, disparity, spacc)
