2013-02-21 16:03:24 -0600	commented question	Stereo_match.cpp to generate point cloud data I can generated a nice disparity image with intrinsics and extrinsics matrices if skipping the reproject step. However, if I incluesd the reproject step, it does give me a pyramid. Does this mean that my calibration wasn't quite right?
2013-02-19 14:14:05 -0600	asked a question	Stereo_match.cpp to generate point cloud data I am using OpenCV 2.4.3 version. When I tried to use stereo_match.cpp to generate point cloud data from a pair of rectified stereo images, the function reprojectImageTo3D generated weird results. The point cloud data looks like a "cone" instead of the real shape of an object. Does anyone have the same experience? Are there other ways to generate 3D point cloud data from a pair of rectified stereo images in OpenCV? Thank you,
2013-01-02 16:37:51 -0600	asked a question	Estimate the volume of a substance taken by a stereo camera I used the LG-P920 stereo cell phone to take the stereo image of a substance, let's say apple. I want to estimate the volume of this apple. Are there any functions/algorithms in OpenCV that can be used to roughly estimate the volume of such a substance? Thank you very much.
