Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a laser radar pod device for an UAV. Background Art

[0002] LiDAR is a radar system that emits laser beams to detect the position, speed and other characteristic quantities of a target. It consists of a laser transmitter, an optical receiver, a turntable and an information processing system. The laser converts electrical pulses into light pulses and emits them. The optical receiver then converts the light pulses reflected from the target into electrical pulses and sends them to the display. LiDAR equipment is usually connected to the bottom of the drone body through a simple mounting device or directly connected and fixed. The drone pod is the main structural device for installing equipment and instruments.

[0003] Most existing drone lidar pods are equipped with a rotating mechanism, allowing the lidar to rotate 306° for multi-angle detection. However, when a drone is operating in complex outdoor environments, dust, moisture, stains, and other impurities may adhere to the outer surface of the glass window, affecting the lidar's signal transmission and reception. For example, dust can scatter laser light, reducing its intensity and accuracy; moisture can form a film, changing the laser's refraction angle. Failure to clean the glass window promptly can affect the lidar's measurement accuracy. Most related technologies only allow the glass window to be cleaned before launching or landing the drone. To address these issues, a lidar pod device for drones is proposed. Utility Model Content
