Design and Calculation Method of GIS High Precision Target Point Collector

摘要: 针对不能使用卫星定位或人员难以到达目标点采集坐标信息的问题,提出利用差分定位模块接收连续运行参数站(CORS)网络差分信息可获得高精度参考点坐标,使用可见光激光测距模块、电子罗盘分别获得目标点距离、方位角和仰角,通过计算获得目标点的高精度坐标,仅需要一次测量即可获得目标点坐标,降低了室外地理信息系统(GIS)信息采集难度,并且可以拍摄目标点现场情况并进行上传,实现照片与目标坐标的自动记录与匹配。设备具有成本低、定位精度高、体积小、功耗低、携带方便、二次开发简单,兼容数据采集等优点。Abstract: Not for the use of satellite positioning or personnel is difficult to reach a collection of coordinate information of the target, this paper uses differential positioning module receives CORS network difference information can be obtained with high precision reference point coordinates, using a visible laser ranging module, electronic compass respectively target distance, azimuth and elevation, obtain high precision coordinates of target through calculation, only one measurement can obtain the coordinate of the target, reducing the difficulty of collecting outdoor GIS information, and can shoot the target site to upload, and automatically records the photos with the target coordinates and matching. The equipment has the advantages of low cost, high positioning accuracy, small size, low power consumption, easy to carry, simple development of the two time, compatible with data acquisition, etc.
