projectPoints function

(Mat, Mat) projectPoints(
  1. InputArray objectPoints,
  2. InputArray rvec,
  3. InputArray tvec,
  4. InputArray cameraMatrix,
  5. InputArray distCoeffs, {
  6. OutputArray? imagePoints,
  7. OutputArray? jacobian,
  8. double aspectRatio = 0,
})

Projects 3D points to an image plane.
