 //! Reprojects disparity image to 3D space.
 //! Supports CV_8U and CV_16S types of input disparity.
 //! The output is a 3- or 4-channel floating-point matrix.
 //! Each element of this matrix will contain the 3D coordinates of the point (x,y,z,1), computed from the disparity map.
 //! Q is the 4x4 perspective transformation matrix that can be obtained with cvStereoRectify.
