采用CCD图象传感器的接触网参数测量系统已研制出来。本文对图象测量原理、系统结构硬件和软件以及信号处理等作了较详细的介绍。给出了实测的拉出值曲线,并对系统的实用化提出了改进措施。
Catenary parameter measurement system using CCD image sensor has been developed. In this paper, the principles of image measurement, system architecture hardware and software, and signal processing are described in more detail. The measured value of pull-out value is given, and the improvement of the system is put forward.
