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 rectifiec 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 rectifiec stereo images in OpenCV?

Thank you,
