Full text of article: Russian language.

Abstract:
In this paper is considered a problem of camera autocalibration (intrinsic parameters identification). This problem is an important part of 3D models building  technology. A conformed identification method is used for intrinsic camera parameters evaluation. It is shown that using of this method enhances the accuracy and reliability of the identification of the calibration matrix of the camera.

Key words:
autocalibration, calibration matrix, camera model, stereoimages, conformed identification, fundamental matrix, projective geometry, epipolar geometry.
