无人机电视图像定位技术,由于采用的单站测角测距方法,存在一些无法克服的不足;空间两点交会定位方法,虽然在一定程度上提高了目标定位精度,但还不能达到高定位精度要求。通过空间三点,建立了空间三点交会定位模型;并且与现有的共线定位算法相结合,通过差分定位原理,达到快速与准确获得任意点坐标的目的。
UAV television image positioning technology, due to the use of single-station goniometry ranging methods, there are some insurmountable deficiencies; spatial two-point intersection positioning method, although to some extent, improve the target positioning accuracy, but still can not achieve high positioning Accuracy requirements. Through three points in space, a three-point model of space intersection is established. Combined with the existing collinear positioning algorithm, the principle of differential positioning can achieve the goal of obtaining the coordinates of any point rapidly and accurately.
