英文摘要： At present, there are a lot of structure damage problems on the surface of high speed rail non-ballasted track in our country, however, the existing detection theories and evaluation methods can't meet the requirement, which should be high precision, high speed, high accuracy and completely automatic. Based on the current research results of our team, which were about highway digitization and information automatic collection system, this project will focus on the non-ballasted track, try to study the integration and working mechanism of the Point-cloud Sensor System, 3D image sensor array, highly accurate Global Positioning System and high-performance data processing system. Secondly, according to the features of non-ballasted track, the high speed and accurate image processing methods will be constructed for surface damage problems of non-ballasted track, by studying the recognition algorithm, description method, classification algorithm and measurement index. Finally, the automatic evaluation method for the surface damage problems of non-ballasted track will be introduced by combining with the existing railway maintain standard, analyzing the observation data and the propagation rules of the surface damage. The research results should be useful to promote automatic testing theories and methods development for the high speed rail non-ballasted track, and also, to afford as the theoretical direction and data supporting for repairing and maintenance of high speed rail non-ballasted track.
