PCT No. PCT/FI87/00048 Sec. 371 Date Oct. 7, 1988 Sec. 102(e) Date Oct. 7, 1988 PCT Filed Apr. 10, 1987 PCT Pub. No. WO87/06353 PCT Pub. Date Oct. 22, 1987.In order to register the space, there are installed two video cameras at certain angles with respect to each other. In this object space there are arranged control points, the object coordinates (Xk, Yk, Zk; k=1, 2, 3 . . . ) whereof are measured and the imagewise image coordinates (xki, yki; xkj, ykj) are determined from the corresponding video cameras, whereafter the control points can be removed from the object space. On the basis of the image coordinate values and the object space coordinate values of the control points, there are calculated the orientation parameters (a11 . . . a33) of projective resection, whereafter the unknown object space coordinates (X, Y, Z) of the observed object points can be solved in a real-time process on the basis of the image coordinates (x, y) registered by the video cameras and by making use of projective intersection.
