The invention refers to stereophotogrammetry field, particularly, to determination of object points coordinates according to the image stereo pair and may be used in the technical vision systems. Summary of the invention consists in the object (1) stereoscopic filming with optical systems (2 and 3), situated on the basis (4). It is simulated the spherical surface by orientating the optical systems (2 and 3) optical axes (9 and 10) so as they could intercross in the point 0, situated on the perpendicular to the basis (4) middle and this point is the centre of the simulated surface. On the object (1) surface it is selected the point A situated on the frontal spherical surface and on the perpendicular to the basis (4) middle and this points is imaged on the photodetectors centres (7 and 8). Each photodetector (7 and 8) is executed as a matrix in the form of a sphear segment and is divided into photodetector rules with photocells. The image is blurried by moving the photodetectors (7 and 8) along the optical axes (9 and 10). On the photodetectors (7 and 8) it is selected two photodetector rules onto which it is imaged the point B of the object (1). It is found the difference of object (1) radiation intensity values in two adjacent photodetector rule photocells, thereafter it is determined the difference of the obtained values of the adjacent photocells two pairs within each photodetector rule. On each photodetector rule it is determined a point in which this value changes its sign and which will correspond to the imaging of the point B on each photodetector. According to the difference of coordinates of point B imaging on two photodetector rules it is determined the distance of the object point from the spherical frontal simulated surface.Claims: 1Fig.: 4<IMAGE>
