Abstract
This paper deals with anon-contact photoelectric detection principle on the position of electric transmission contact net in electrification railway. Both vertical distance and horizontal deviant of the electric transmission contact net is measured simultaneously by using planar array CCD components and adopting triangle indirect algorithm. We analyze systematically call kinds of factor effecting measurement accuracy and put forward a calibration method decreasing error, and we also introduce circuit principle and digit processing algorithm.
