Method requires no special equipment to monitor the camera position, and it can be used for live content, as well as an archive material. Invention uses the advantage of initial material to be replaced, in a specific case, when the object to be replaced is filled in electronically.

EFFECT: technical result is inserting replacement images into a video stream without the need to receive and transmit parameters of the camera via a sensor equipment mounted on a tripod and without the need of a static model of the real environment.
