摘要
为了实现对大靶面、高速飞行的小目标进行精密测量,研究了采用多台CCD像机组成条带式弹道像的实现方法和交汇测量的原理,导出了交汇测量坐标的计算公式,利用误差理论对本系统的测量精度进行了详细的分析。研究结果表明,条带式弹道像机能够提高对目标的捕获几率,能够有效的提高坐标测量精度。
In order to engage a precise measurement on small target highly flying in large range, adopting many CCD cameras to compose trajectory camera with long narrow photosensitive surface is studied. Based on intersection measuring principle, it leads out computing formula of intersection measuring coordinate. The measurement accuracy is carefully analyzed by the error theory. The results prove that the capture probability as well as the coordinate measuring accuracy can be highly improved using trajectory camera with long narrow photosensitive surface.
