摘要
基于透视投影变换和空间解析几何理论,提出了一种新的激光自准直测角模型建立方法,通过对像点的椭圆轨迹中心与系统基准零位的分析,建立了基准零位畸变误差模型,并进行了仿真研究,获得了该误差的变化规律,为激光自准直测角系统标定、基准零位的确定等问题的有效解决提供了一个有效的理论依据,具有一定的理论意义和工程实际应用价值。
Based on the theory of perspective projection and the theory of spatial analytic geometry a new modeling method of laser auto-collimation angle measurement is proposed. Through analyzing on the center of ellipse track of spot and reference zero of system, a mathematical model of this distortion error of the reference zero is established. Meanwhile, the simulation is done and some conclusions about the distortion error are drawn. An available theoretical reference for the system calibration of laser auto-collimation angle measurement or the obtainment of the reference zero is proved. Thus it is really significant in theory and is valuable in engineering applications.
