Abstract. Approaches to development of software component for module of lengthy objects shooting for sawn timber scanner are described. The use of known image recording algorithms is shown to simplify the scanner designing. The proposed algorithm of the software component operation is a computational graph; and the computational operations performed during processing of the survey frame are listed. An algorithm for separating the object from the background is presented. An algorithm of full search for the comparison of control points between frames and the RANSAC algorithm, which is used to construct the transformation model, is chosen. The implementation scheme of the RANSAC algorithm is compared with the PROSAC algorithm.

Keywords: technical vision, machine vision, scanner of sawn timber, image recording algorithms, RANSAC method, PROSAC method, library OpenCV
