project_point_hom_mat3dproject_point_hom_mat3dProjectPointHomMat3dProjectPointHomMat3dProjectPointHomMat3d applies the 3×4 projection matrix
HomMat3DHomMat3DHomMat3DHomMat3DhomMat3D to all input points
(PxPxPxPxpx,PyPyPyPypy,PzPzPzPzpz) and returns an array of output
points (QxQxQxQxqx,QyQyQyQyqy). The transformation is described by
the 3×4 projection matrix given in HomMat3DHomMat3DHomMat3DHomMat3DhomMat3D. This
corresponds to the following equations (input and output points as
homogeneous vectors):
project_point_hom_mat3dproject_point_hom_mat3dProjectPointHomMat3dProjectPointHomMat3dProjectPointHomMat3d then transforms the homogeneous
coordinates to Euclidean coordinates by dividing them by Tw:
If a point on the line at infinity (Tw = 0) is created by the
transformation, an error is returned. If this is undesired,
project_hom_point_hom_mat3dproject_hom_point_hom_mat3dProjectHomPointHomMat3dProjectHomPointHomMat3dProjectHomPointHomMat3d can be used.
Note that, consistent with the conventions used by the projection in
calibrate_camerascalibrate_camerasCalibrateCamerasCalibrateCamerasCalibrateCameras, QxQxQxQxqx corresponds to the column
coordinate of an image and QyQyQyQyqy corresponds to the row
coordinate.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
