  • Patent number: 11972507
    Abstract: 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.
