摘　　要：针对无人机搭载的非量测数码相机存在的像片数量多、像幅小、基线短、像片像主点位置精度差等问题,以实际项目为例,通过无人机搭载GPS接收机得到高精度的像片像主点位置信息,从而有效减少地面像控点数量,达到大比例尺地形图测绘要求,并得到满足不同比例尺及精度要求的像控点布点方式,为相关作业提供借鉴。In view of a series of problems,such as large number of photos,small image size,short baseline and poor positional accuracy of the main point of the photo image in the non-measurement digital camera carried by UAV,the study takes the actual project as an example,and obtains the high-precision photo image main point position information through the UAV equipped with a GPS receiver,to effectively reduce the number of ground image control points,meet the requirements of large-scale topographic map mapping,and obtain the layout methods of image control points under different scales so as to provide reference for the related work.
