Abstract
Currently, rail transit has developed more and more intelligently, and intelligent vehicles are of significance in reducing traffic accidents and improving transportation capacity and have broad market prospects. This research combines infrared image acquisition and machine algorithms for obstacle recognition. The SURF algorithm performs feature extraction and description, and elimination of mismatched point pairs on infrared and visible light images, which can do image recognition on track obstacles. On this basis, a foreign object monitoring system consisting of an optical imaging subsystem, a lighting and detection light source subsystem, a pan tilt synchronous control subsystem, an image acquisition and processing subsystem, and an installation fixture and protection subsystem was designed. Finally, a demonstration application of foreign object monitoring under different working conditions in the section adjacent to the elevated line and highway of Guangzhou Metro Line 4, the open line section (K46+175) from Tung Chung Station to Huangge Auto Town station, for the 100 m section of the uplink and downlink double lines was carried out on the proposed system, which verified that the foreign object detection rate was 100% based on the test data, and the maximum detection response time was 4s (less than 5s). The relative deviations between the detected foreign objects and actual positions were less than 2.13% and the relative deviations between the detected foreign objects sizes and the actual sizes were less than 8.8%, which fully proved the effectiveness of the monitoring system.
