光电经纬仪利用雷达距离数据实现单站定位方法研究

Position Measure Method Researsh for Theodolite Using Radar Distance Data

为了解决经纬仪快速定位问题,提高其使用效率,提出利用在光电经纬仪附近同站位两维雷达距离测量数据,结合光电经纬仪俯仰角测量数据,将雷达测量的相对于目标的距离数据转换到经纬仪相对于目标的距离数据,从而实现单站定位方法。经过误差分析表明,定位精度小于5m,满足对目标定位精度要求。同时经纬仪不需要与其它经纬仪交会即可对目标定位,减小了经纬仪对布站的限制。

In Order to resolve the rapid positroning of the theodocite, improve using efficiency, giving to target position measurement method for theodolite using 2D radar distance data in a same station, combining pitch angle measurement datas of theodolite, conversioning radar measuring data to theodolite distance to target. Position error analysis indicate, when the position measured precision less than 5m, meeting position measured demand to target. The theodolite position measured does not need intersection measurement with other theodolites, which reducing the limit to the theodolites station.
