Description

technical field [0001] The invention relates to the field of urban rail transit boundary detection, in particular to a digital boundary dynamic detection system and detection method for subways. Background technique [0002] In the urban rail transit industry, the development of subway boundary detection technology is becoming more and more mature. After a lot of research and testing, a variety of subway boundary detection equipment has been developed. From the working principle, it can be divided into contact measurement and non-contact measurement, portable measurement and vehicle measurement. For the section detection of long-distance subway tunnels, vehicle-mounted measurement is generally used, while portable measurement is only used for supplementary measurement of some individual sections. [0003] At present, more advanced foreign subway limit detection vehicles mostly use laser and image processing technology, and the running speed of the detection vehicles ranges ...
