摘要

本文针对传统地面炸点测试系统受地形及机动条件约束无法满足试验火力压制科目中落点脱靶量测量的问题，提出研制一套在无人机上安装自动指向摄像系统的高空拍摄装置。利用地面设置的外定标完成摄像系统内部参数修正，通过像面修正和目标位置提取，实现弹丸地面落点的高精度测试坐标的获取。实验结果表明，利用本文建立的系统，相机的成像大小为727.9 m×352.7 m，成像精度能够满足弹丸散布范围纵向100 m及横向300 m的测试需求；在探测器像元数为4 096×2 048的情况下，相机的成像精度较高，满足测试精度的试验要求。本文方法具有重要的理论意义及应用价值。

Abstract

Aiming to the problem of miss distance measurement in the suppression

which generates by the restriction of topographies and movements in the traditional burst points test system

a set of pointing system in air is established

and it is installed on an unmanned plane. By utilizing the external calibration

the internal parameters of the image pickup system are corrected. And then by correction of image plane and target position extraction

the ground points of the projectiles are obtained exactly. The experiment result shows that the imaging size of camera is 727.9 m×352.7 m

which meets the test requirement within 100 m in horizontal and 300 m in vertical. In addition

the precision of camera is 0.1 m when the pixel number is 4 096×2 048

which meets the requirement that the test precision is less than 0.3 m. The proposed method has the theoretical value and the practical significance.
