    Abstract
  • Aiming at the problem of large number of field control points and heavy workload in the spatial triangular processing of unmanned aerial vehicle , the BeiDou Navigation Satellite System (BDS) assisted unmanned aerial vehicle large-scale image control free accuracy verification method is proposed in this paper. The unmanned aerial vehicle photogrammetry platform equipped with dual frequency Global Navigation Satellite System (GNSS) receiver is used to receive BDS data. The key technologies of high-precision BDS camera station coordinate solution and joint adjustment of BDS data and unmanned aerial vehicle image data are discussed and analyzed. Finally, an engineering example is given to verify the effectiveness of the method. The experimental results show that the method can meet the accuracy requirements of 1∶500 large scale mapping without the participation of image control points.
