 Automatic matching of low-altitude remote sensing images and high-precision aerial triangulation (see Figure 1):
 1. Use the low-altitude remote sensing platform to obtain single or multi-airband images of the target in the survey area according to the following image shooting methods, and import the images into the computer:
 During the flight of the low-altitude platform, it is impossible to strictly follow the preset route to fly in a straight line, and the attitude angle of the digital camera cannot be kept fixed. Therefore, when designing the route, it is generally necessary to design the route according to the range of the survey area, the camera parameters and the preset ground resolution. In-band overlap 80%, between air belt 40% overlap Design route and low-altitude remote sensing platform flight height, to ensure that the obtained low-altitude remote sensing images fully meet the minimum overlap requirements; low-altitude remote sensing platforms c...
