Webthe output disparity can be CV_16S or CV_32F. 1. When disparity's type is CV_16S : disparity values scaled by 16. To get the true disparity values from such it, you will need to divide each element by 16. 2. If disparity's type is CV_32F, then the disparity map will already contain the real disparity values on output.
