应用于铁轨平直度检测的激光测量系统的研究

为了能够对铁轨的平直度参量进行精确测量,设计了一种基于自准直原理的嵌入式激光测量系统,其检测系统主要由图像采集和传输模块、图像处理和数据处理模块及激光测距模块组成,系统将接收的光斑图像通过一系列图像处理后,将距离参量和图像参量带入自准直算法中,求得铁轨平直度偏移量,并能够保证其测量精度在0.3mm.结果表明,该系统可以在一定程度上代替传统的轨道测量方法,使得测量过程更加简便、精确.

Resarch of Laser Measurement System for Rail Linearity Detection

For the situation that there is a blank at the instrument of rail linearity detection, we designed an embedded laser detection system based on autocollimat theory, the detection system is mainly composed of image acquisition and transmission module, image processing and data-processing module, laser range module, the system process the spot image through a series of image processing, then put the distance and image parameters to the autocollimat algorithm, and the rail linearity offset can be obtained, the measuring accuracy is 0.3mm. The system can replace the traditional manner of rail detection, also make the detection process more simple and accurate.
