High-Precision and Light-Small Oblique Photogrammetry UAV Landscape Restoration Monitoring

In recent years, the state has carried out landscape restoration for the Da Bijia Mountain many times. In order to master the effect of landscape restoration, 3D image data of the Da Bijia Mountain were obtained by UAV with high-precision and light-small oblique photogrammetry, and a series of data processing method as multi-vision image joint adjustment and Dense matching of multi-vision images was carried out to enable the 3D image production. Using the 3D image of the Da Bijia Mountain, plus with the evaluation of its renovation and repair effect, and through the method of surface area measurement to calculate the amount of renovation and repair quantities, the results showed that the amount of engineering quantities calculated by this method was similar to the actual amount, which provided an effective technical method for landscape restoration and monitoring in the future.
