AI Technical Summary

Problems solved by technology

[0005] 3. The power supply provided by the UAV is limited, and it cannot provide high-power power supply like the ground equipment. Therefore, the airborne task load is required to have low power consumption

Visible light sensors can obtain rich and delicate visible light images, but their imaging quality is seriously affected when the lighting conditions are poor; infrared detectors have better target detection capabilities at night and other poor lighting conditions, but their infrared Image detail performance is poor

Especially for low-resolution infrared imaging equipment, the number of detector pixels is limited, and the edges of the output infrared image are blurred, which limits the development of infrared imaging equipment in the direction of high performance and lightweight

In addition, if the UAV loses stars during the flight, the attitude is easy to diverge, which will directly lead to the failure of the mission or even the crash of the aircraft.
