摘要
介绍目前两种轨道板检测方法并分析各方法的优缺点,提出近景摄影测量技术应用于检测轨道板的新方法。通过实验分析验证摄影测量方法检测轨道板的可行性,并从进一步提高检测轨道板效率的角度,提出需要解决的关键问题和检测方法的具体方案。
Two kinds of test methods for track slab are presented, and analyzed the advantages and disadvantages of each method. A new method by use of close-range photogrammetry technology to test track slab is provided. The feasibility of using close-range photogrammetry technology has been verified. For improving the efficiency of this detection method, a corresponding program is established.
