利用坐标变换计算光电转台误差的方法

Calculation method of optoelectronic turntable error through coordinate conversion

红外搜索跟踪系统是一种被动式的探测系统,能够实现对红外目标的检测、识别以及跟踪工作。同时,红外搜索跟踪设备在多传感器融合方面也起着重要的作用。多传感器融合的前提是实现多传感器的空间统一。然而,光电转台的指向精度在很大程度上会影响多传感器空间统一的准确性。利用坐标变换的方法分析了光电转台的主要误差,并设计相关的试验,为实现多传感器空间统一提供一种有效的误差计算方法。

Infrared searching and tracking system is a passive detection system,which can realize the detection, recog- nition and tracking of infrared target. Meanwhile ,infrared searching and tracking system also plays an important role in multi-sensor fusion. The multi-sensor spatial unity is the premise of multi-sensor fusion. However, the measurement er- ror of optoelectronic turntable will affect the accuracy of the multi-sensor spatial unity. The main errors of optoelectron- ic turntable are analyzed by coordinate conversion method, and the related experiments are designed. An effective way of error calculation method is provided for the multi-sensor spatial unity.
