数字式靶道阴影照相系统

Digital Ballistic Range Shadowgraph System

介绍了一种基于脉冲激光光源和高分辨率CCD摄像技术的数字式靶道阴影照相系统,论述了该系统的组成和工作原理.给出了根据图像数据处理弹丸俯仰角和偏航角及质心坐标的方法,实现了二次短脉冲闪光的数字式靶道阴影照相系统,经过靶道射击试验取得了弹丸姿态和速度信息.实验结果表明,本数字化系统可以有效替代传统的火花胶片式靶道阴影照相系统.

Based on the technology of pulses laser source and high resolution CCD cameras, a digital ballistic range shadowgraph system was introduced. The working process and constitution of the system were described. Based on digital graph, the method of attitude calculation （pitch, yaw of the bullets） and bullets mass point identification were presented. The digital range shadow- graph system with double short-pulse flash was realized. By experiment, the bullet attitude and velocity were obtained. The test results indicate that the traditional ballistic shadowgraph system consisting of spark source can be replaced by digital system effectively.
