Embodiment Construction
[0017] Compared with the existing coordinate point positioning method, a method using ordinary digital camera method combined with GPS / RTK / CORS photography positioning method in the case of UAV spinning in the sky / high ground / roof has made a greater effort in the operation process and calculation model. Improvements and innovations, specifically:
[0018] (1) if figure 1 As shown, for the three photogrammetry situations of UAV gyration / high ground / roof, first, determine the location of the measurement area, and select the high-level viewing point S 1 , S 2 As the shooting site, the three-dimensional object coordinates (X s1 , Y s1 ,Z s1 ) and (X s2 , Y s2 ,Z s2 );
[0019] (2) Use a fixed-focus ordinary digital camera (with a focal length of f) to take pictures of the target area to be measured, among which, it is necessary to ensure that there are more than 2 control points in each camera photo, and at the same time measure all control points with the help of GPS / RTK / ...
