Abstract: An obtaining method for image coordinates of a position invisible to a camera, a calibration method and a system are disclosed. A first color image and corresponding depth image of a position to be measured invisible to a main camera are obtained from a depth camera. The depth camera is positioned so that the position to be measured is within a field of view of the depth camera. Three-dimensional coordinates of the position to be measured are extracted from the first color image and corresponding depth image. And the three-dimensional coordinates of the position to be measured are converted into the required image coordinates of the position to be measured by a translation matrix and a rotation matrix for converting a depth camera coordinate system into a main camera coordinate system. The translation matrix and the rotation matrix are determined by calibration between the main camera and the depth camera.
