The first two are based on projective transformation and DLT coefficients through which the position of the perspective center is derived first using four or more planar and six or more non-planar object points, respectively. The rotation matrix is then directly estimated using quaternions. The third one (quaternion-based general approach) can handle three or more points in either planar or non-planar configuration. In this approach, the rotation angles are iteratively estimated first using quaternions without the need for user-defined approximations. Then, the position of the perspective center is directly derived. Experimental results show the feasibility of the proposed approaches and the high accuracy of the quaternion-based general approach, which is superior to the state-of-the-art non-iterative method and does not deviate more than 1 percent from the traditional non-linear SPR, i.e., the de-facto standard for the most accurate SPR solution.
