摘要
Disclosed is an orthophoto map generation method based on a panoramic map, the method comprising: overlapping and fusing a panoramic map and panoramic field depth data when the panoramic map is photographed, such that each pixel of the panoramic map has a corresponding field depth value; acquiring a pitch angle and azimuth angle of a reference pixel relative to a photographing device, and in conjunction with a 360 degree feature of a panorama, calculating an azimuth angle and pitch angle, relative to a camera, of an object represented by each pixel; in conjunction with calculation results and geographic coordinates, determined by a positioning device when the panoramic map is photographed, of the camera, calculating a geographic position corresponding to the object represented by each pixel to form point cloud data; and according to a certain rule, eliminating and fusing point cloud data generated by adjacent panoramas, and projecting a result onto a plane to obtain an orthophoto map. The orthophoto map obtained based on the method has the advantages of high precision, high resolution, etc., and compared with traditional orthophoto maps obtained by means of satellites and aerial photography, the orthophoto map acquired based on the method will not be impacted by obstacles such as a tree canopy.
