Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle reconnaissance image processing, and specifically refers to a ground real-time reconstruction processing system for unmanned aerial vehicle reconnaissance images. Background technique [0002] Reconnaissance is the inherent mission of UAVs. The long-distance non-contact reconnaissance technology based on UAVs has become the main technical means of intelligence collection. Compared with satellite reconnaissance, it has its own advantages, such as low cost and reconnaissance area control. It is flexible, does not have access time and period restrictions, and has high resolution of ground targets. Compared with manned reconnaissance aircraft, it can continue to work day and night without considering factors such as pilot fatigue and casualties. Therefore, in view of the advantages of high resolution, high flexibility, high efficiency and low cost, UAVs are widely used in military and ...

Problems solved by technology

However, in the process of practical application, the UAV reconnaissance images have exposed the following important problems: 1) The UAV is affected by factors such as its own attitude and the instability of the imaging platform, the arbitrariness of the attitude of the imaging platform, and the scattering of atmospheric radiation. 2) Due to the influence of factors such as flying height and camera focal length of the UAV, the geographical range that can be reflected by a single reconnaissance image is relatively small. Small size, it is difficult to use one reconnaissance image to reflect all the information of the area of ​​interest; 3) Due to the limitation of the imaging principle of a single type of sensor, the reconnaissance image captured by a single sensor often cannot reflect all the detailed information of the effective target in the reconnaissance area

Due to the above defects in UAV reconnaissance images, the reconnaissance performance of UAVs is seriously affected.
