Transformation

This node holds an approximate homogeneous transformation matrix which can be used to transform pattern points to image points. E.g. applying the transformation matrix to the point (0, 0, 1) will return a homogeneous point (a, b, w) representing the pattern center. The center is then at pixel coordinates (a/w, b/w). Transforming (1, 0, 1) will give you the approximate position of the first point in the patterns x direction, etc.

Note

The transformation cannot account for camera distortion present in the raw images, so the point positions computed via the transformation matrix will always be approximations. Use GetPatternBuffers instead if you want to access the actual raw image coordinates.
