The invention relates to an underbody clearance detection method and system for a railway vehicle, and the method comprises the following steps: (1) monitoring and obtaining an underbody clearance two-dimensional matrix S0 [m, n] of the whole train; (2) obtaining the train section number K, the points Nk and Mk of data in the length direction and the width direction of each train section, and a train bottom clearance two-dimensional matrix Sk of each train section through a train division algorithm; (3) the vehicle bottom clearance two-dimensional matrix Sk [m, n] of each vehicle corresponds to the actual position of the vehicle bottom through a point cloud construction algorithm, and actual coordinates Pk, m, n [x, y] corresponding to each data point in the Sk [m, n] are obtained; and (4) through a clearance extraction algorithm, extracting T lowest clearance values at the bottom of each vehicle and positions of the T lowest clearance values. The vehicle bottom clearance detection method ...

The invention provides a road crack detection system based on semi-automatic labeling, which comprises an information acquisition module, a crack identification module, a data management module and a front-end display module, and is characterized in that the data management module adopts a distributed file management system and can dynamically store road surface information and extract key frames for storage. According to the invention, rolling optimization is carried out on the model of the crack identification module by using the key frame sample data set of the data management module, and semi-automatic marking is carried out on large-scale unmarked images of a video by using the optimized model, so that a large number of training data sets and the optimized crack identification model are obtained, the labor cost is reduced, and the efficiency is improved. The automation degree is high, and the labeling and recognition detection precision is continuously improved.
