Abstract: t is need to experiment to verify the correctness and validity of various stages in system design after gauge visual detection system designing between high signals and contact net. Then it does error analysis from lighting conditions, camera resolution, binocular imaging system installation structure, camera out of synchronized, noise and subsequent image processing operations, etc. It analysis the systematic errors principle and specific impact, then identifies specific improvements.

Abstract: The gauge detection between high signal and contact net is an important part in railway safety production. According to the detection nature, this paper designed a visual detection system to solve the problem of gauge detection between high signal and contact net. Using template matching method to break up the gray target image, and using discovering turning point method to rebuild target in space. Then according to the principle, it prepared detection system based on VC++2008 and OpenCV. The experiment results showed that: measurement error was within士15mm, when detection distance was arrange from 45.0m to 55.0m. Detection system which had high accuracy and good reliability, met system design requirements.

Abstract: It plays an important role to detect gauge between high signal and contact net in railway safe, to provide safe guarantee for railway workers. This paper proposed a visual detection model to solve the problem of gauge between high signal and contact net. Base on three-dimensional reconstruction high signal and contact line with space points, it transformed two objects coordinate, then analyzed the position relationship and accurately solved the shortest distance from high signal to contact line, last compared with the standard gauge to achieve the process of gauge detection.
