On July 26, a 3D rail track patrolling system was successfully put into trial operation in Shuohuang Railway of CHN Energy. The system can complete the workload that formerly required 720 hours of manual patrols within 48 hours, improving the work efficiency by 15 times while reducing the safety hazards of personnel in the process of road patrols. This marked a new stage of heavy-haul railways with intelligent patrolling replacing manual patrolling.

Based on line structured light and machine vision technologies, the 3D rail track patrolling system uses 3D laser vision sensors to collect three-dimensional images and data of rail infrastructures such as rail tracks, fasteners, sleepers, track beds, etc., and then processes and calculates the data through the three-pronged intelligent detection and evaluation algorithm of "data comparison + template matching + machine learning", so as to realize the qualitative and quantitative identification of track visual hazards and risks. It can also automatically output key information such as the location, type, and value of connected parts, rails, joints, sleepers and track bed hazards, thus providing an objective basis for track maintenance and repair. The system can replace manual patrolling, greatly improve the detection speed and accuracy, increase the overall efficiency of rail line inspection, and enhance the intelligent level of heavy-haul railways.
