摘要：

针对坦克行进间火炮身管弯曲测量缺乏手段,评估其对射击准确度的影响缺乏数据的现状,在综合分析现有身管弯曲测量方法的基础上,提出炮尾安装高分辨率和高帧频线阵CCD、炮口固定指示标靶的基于计算机视觉的测量方案,论述系统组成、测量原理和测量准确度,分析测量距离、CCD成像系统姿态等装配问题对测量准确度的影响。结果表明:该方案在实现实时高准确度身管弯曲测量的同时,解决测量系统在进行高速高准确度测量时数据量大、存储和处理难的问题;实现系统的自标定,降低系统的装配准确度要求,提高系统的实用性,具有一定的创新性和现实意义。

Abstract: There are no appropriate ways to measure the gun barrel bending of a marching tank at present, and thus there are no adequate data to evaluate their impact on the firing accuracy. Based on comprehensive analysis of existing methods for measuring gun barrel bending, a new measuring system with line-scan CCD of high resolution and frame rate installed in the gun breech and a displacement-indicating device fixed on the muzzle is proposed. This paper has discussed the principle and accuracy in measurement and analyzed the error in distance measuring, CCD pose and assemble problems of the system. Results show that the scheme can not only measure the barrel bending in real time and at a high precision, but can solve data storage and processing. In addition, it has, through self-calibration, made the system less demanding for assembling precision and more practical, and have certain innovative significance.
