[0002] In the surveying and mapping technical field, the unmanned aerial vehicle aerial photogrammetry technology is used more and more in various production constructions as a new surveying and mapping means. With the increase of the depth and area of the metal mine caving method mining, the ground of the metal mine caving method mining appears obvious subsidence, and the ground has produced many subsidence pits and cracks, so it is urgent to ensure the safety of the metal mine caving method mining and further provide effective and high-precision ground monitoring data support for the caving method mining, and the unmanned aerial vehicle aerial photogrammetry ground subsidence monitoring is needed. When the unmanned aerial vehicle aerial surveying is carried out, a certain number of image control points need to be arranged in the ground subsidence area, and the number and quality of the image control points directly affect the precision of the unmanned aerial vehicle aerial photogrammetry monitoring of the metal mine caving method mining ground subsidence.
[0003] At present, in order to conveniently arrange the unmanned aerial vehicle aerial surveying image control points, the image control points are mostly arranged randomly, a simple ribbon or paper strip is laid on the flat ground to form an image control point identification of a cross structure, and the surrounding stones and soil are used to prevent the image control points from being damaged and lost. However, for the metal mine, the surrounding is surrounded by mountains and gobi, and the caving method mining has caused the ground to appear obvious subsidence, so the unmanned aerial vehicle aerial photogrammetry monitoring image control points are more easily affected by natural factors (mainly wind), human factors (mainly human damage) and ground subsidence, many image control points are easily displaced or damaged, and the quality of the image control points and data processing interpretation are seriously affected. Therefore, a kind of unmanned aerial vehicle aerial surveying image control point identification for metal mine caving method mining ground subsidence monitoring needs to be developed.
