Construction of digital terrain models for testing active-pulse television measuring systems

Abstract

The paper considers algorithm for creating a dense cloud of points and an orthomosaic plan of the terrain based on images obtained from a television camera of an unmanned aircraft. Geographic referencing of models is carried out using control points, the exact coordinates of which are determined by the instrumental method in the required coordinate system. The analysis of the number of identification marks involved influence in photogrammetric processing on the final model accuracy is carried out. The possibility of using the obtained models for testing active-pulse television measuring systems is considered.
