Problems solved by technology

For example, although structured light obstacle avoidance technology and light wave time-of-flight obstacle avoidance technology are used at night, they are easily interfered by strong light during the day, which affects their sensing effect
Although the ultrasonic time-of-flight obstacle avoidance technology is compatible with day and night, sound wave sensing is easily affected by environmental noise and sound-absorbing behavior of objects, and the speed of sound wave transmission is slow, which easily affects the movement speed of drones, so it is not applicable in unmanned aerial system

Abstract

The invention discloses an unmanned aerial vehicle obstacle avoidance system and a control method thereof. The unmanned aerial vehicle obstacle avoidance system comprises a cover body, at least two obstacle avoidance lens modules and an infrared light source. The infrared light source is located between the at least two obstacle avoidance lens modules. Each obstacle avoidance lens module comprisesa sensing unit and an infrared shutter. The sensing unit comprises a filter layer and a sensing element. The filtering layer is located between the cover body and the sensing element, the filtering layer is provided with at least one filtering area, and one filtering area is an infrared filtering area. The infrared shutter is located between the cover body and the sensing unit and used for switching the infrared cut-off piece to be in an open state or a closed state. The unmanned aerial vehicle obstacle avoidance system and the control method thereof provided by the invention can be applied to daytime and night environments.

Description

technical field [0001] The present invention relates to an obstacle avoidance system and its control method, and in particular to an unmanned aerial vehicle obstacle avoidance system and its control method. Background technique [0002] In recent years, UAV products have gradually developed from consumer products to industrial application products. At the same time, in order to improve the efficiency of industrial applications, various manufacturers are trying to introduce fully autonomous operation functions into UAV systems. In the fully autonomous operation mode, since there is no manual remote control assistance, the drone must judge the objects in front of it by itself and dodge in time to maintain normal and stable work. Therefore, obstacle avoidance is the most important and necessary function for unmanned aerial vehicles with industrial application products. [0003] The obstacle avoidance technology currently used in drones is dual-lens obstacle avoidance technolo...
