摘要:
为确保运营期间地铁车辆运行、停靠与旅客乘降的安全，需要定期对地铁站台限界进行检测。目前使用较多的接触式检测存在检测效率低，人为影响因素较大等缺点。基于机器视觉技术研究了一种非接触式站台限界检测仪。采用三角测量原理，提出基于基准点匹配的标定方法，解决近景斜角大范围摄影测量问题。通过现场测试数据分析，检测仪满足了地铁站台限界侵限检测需求。
Abstracts:
In order to ensure the safety of metro train running, stopping and passenger landing, it is necessary to check the metro platform gauge and line maintenance periodically during long-term operation. At present, the regular contact detection has many disadvantages, such as low detection efficiency and greater human influencing factors. A portable non-contact platform gauge detector based on the machine vision technology is developed. Then, a calibration method based on reference point matching is put forward by adopting the triangulation principle, aiming to solve the problem of large-scale photogrammetry from the close-range oblique angle. Through field test and data analysis, the measurement accuracy could meet the detection requirements of metro station platform boundary intrusion.
