摘要

针对传统光学成像测量方法对高速运动目标成像帧频低、像质模糊, 难以满足对目标形变高精度测量的缺点, 提出一种基于线阵CCD像素数提取的高速运动目标形变测量方法。该方法利用线阵CCD高分辨率、高帧频等优势, 通过提取线阵CCD输出目标强度——像素曲线斜率变化率最大点来获取目标所占像素数N的像素数提取方法, 同时采用DMD模拟高速运动目标形变过程, 配合基于线阵CCD像素数提取的高速运动目标形变测量方法进行形变测量实验验证。实验结果显示采用该方法对V=450 km/h的高速运动目标进行形变量测量时, 可以满足目标形变测量偏差小于0.3 mm, 标准差小于0.5 mm, 相对误差最低0.01%。实现了高速运动目标形变量的准确测量, 为高速磨损测试、高温形变测试、高压形态测试等奠定了基础。

Abstract

Aiming at the shortcomings of traditional optical imaging measurement methods, such as low frame frequency, blurred image quality and difficulty in meeting the requirements of high-precision measurement of target deformation, a new method of high-speed target deformation measurement based on linear CCD pixel number extraction was proposed.This method takes advantages of the linear charge-coupled device (CCD), such as high resolution and high frame frequency. The pixel extraction method for obtaining the target number N of pixels was used by extracting the line array CCD output target intensity-the maximum point of the slope change rate of the pixel curve. At the same time ,the digital micromirror device(DMD) was utilized to simulate the high-speed moving target deformation process , combined with the linear CCD pixel number extraction based high-speed moving target deformation measurement method to conduct experimental verification. The experimental results show that the deformation of the high-speed moving target with V=450 km/h can be measured by the method proposed, which can meet the requirements for the target deformation measurement deviation less than 0.3 mm, the standard deviation less than 0.5 mm, and the lowest relative error of 0.01%. The accurate measurement of the high-speed moving target shape variable is realized, which lays a foundation for high-speed wear test, high-temperature deformation test and high-pressure shape test.
