摘要

设计了一种由LED靶标、成像透镜及面阵CMOS组成的重载车辆车架形变测量系统,可用于导弹发射车发射架形变检测。在车体上搭建成像系统,通过监测LED靶标在CMOS上成像位置的变化得到车体在垂直于光轴平面内形变量大小,并实时将结果输出至上位机系统。实验结果表明,该系统能准确测量靶标点相对于成像系统的变化,具有精度高、实时性好等优点。

Abstract

A measurement system of heavy duty truck frame deformation which is composed of a LED target, a lens and a CMOS camera is designed to be used for the deformation detection of missile launch vehicle launch frame.The imaging system is built on the vehicle body, so the change of the body deformation in the vertical plane is obtained by monitoring the change of the imaging position of the LED target on the CMOS. The measured results are real-time output to the higher-level software. The experimental results show that the system, with the advantages of high precision and good real-time performance, can accurately measure the variation of the target point with respect to the image system.
