摘　　要：无人机载光电吊舱在执行地面目标的搜索与跟踪任务时,需对锁定的地面目标位置进行精确定位解算。文中阐述了无人机载光电吊舱的光电探测器锁定地面目标后,无人机将机载GPS信息、姿态信息、航向角及光电吊舱的方位角俯仰角等直接测量的物理数据发送给地面站;地面站通过对光电吊舱球面坐标系到WGS-84坐标系等一系列坐标转换,解算出光电探测器视轴与地面交点的位置信息;同时结合实际应用对定位精度进行了简要分析。When the unmanned-helicopter airborne electro-optic pod administers the mission of tracking and searching,it needs to precision calculate the location of the locked target.The article researches a target localization method that the electro-optic detector of the unmanned-helicopter airborne electro-optic pod locked target,unmanned-helicopter sends the date of the relatively sensors information to the ground station.By using a series of coordinate transformation from spherical coordinates of the electro-optic pod to WGS-84 coordinates,the ground station can calculate the nodical information of the photodetector oculometric axis and ground.In addition,the precision of location is briefly analysed with practical application.
