[−][src]Function opencv::cudastereo::reproject_image_to_3d

pub fn reproject_image_to_3d(
    disp: &dyn ToInputArray, 
    xyzw: &mut dyn ToOutputArray, 
    q: &dyn ToInputArray, 
    dst_cn: i32, 
    stream: &mut Stream
) -> Result<()>

Reprojects a disparity image to 3D space.

Parameters

  • disp: Input single-channel 8-bit unsigned, 16-bit signed, 32-bit signed or 32-bit floating-point disparity image. If 16-bit signed format is used, the values are assumed to have no fractional bits.
  • xyzw: Output 3- or 4-channel floating-point image of the same size as disp . Each element of xyzw(x,y) contains 3D coordinates (x,y,z) or (x,y,z,1) of the point (x,y) , computed from the disparity map.
  • Q: inline formula perspective transformation matrix that can be obtained via stereoRectify .
  • dst_cn: The number of channels for output image. Can be 3 or 4.
  • stream: Stream for the asynchronous version.
