Abstract
The combination of engineering geodesy methods with computer processing of digital images on the matrix field of analysis has found wide application in various automatic systems for monitoring the mutual spatial position of elements. The use of stereoscopic schemes allows to control the spatial position of the railway track relative to the brands placed on the supports of the contact network. When moving along the path in such schemes, additional errors arise due to blurring on the photo-receiving matrix fields. The article discusses the methodology for estimating additional errors due to the movement of the stereoscopic optical-electronic system relative to fixed reference marks. Ways to reduce additional errors from the speed of movement by adaptive control of the size of the input apertures and the exposure time of images on photo-receiving matrix fields are proposed.
