摘要
以无人机作为低空遥感平台,将选择的轻小型量测相机与定制的小型双频高动态GPS进行搭载集成,并自主研制了一种三轴稳定云台装置,可保持无人机航摄时相机姿态的稳定,使获得的航空影像满足大比例尺测图的规范要求。将该系统应用于1∶500大比例尺地形图测绘项目,结果表明该系统的成图精度完全可以满足国家航测内业成图规范及城市测量规范要求。
In this paper, unmanned aerial vehicle （UAV） is used as a low altitude remote sensing platform. On the basis of integration of small light measurement camera with dual frequency high dynamic GPS, a three axis stabilized platform device can stably keep the camera attitude angle of UAV, make digital image shooting can meet the requirements of large scale mapping. The system is successfully applied in the 1：500 large-scale topographic mapping project. The experimental results show that the accuracy of the system can be well suited to the requirements of the national photogrammetric mapping standards and the urban surveying standards.
