Study of high-resolution helicopter cable obstacle avoidance LIDAR

A high-resolution helicopter cable obstacle avoidance LIDAR is designed by the laser parallel scanning method, combined with the 3 × 2 rectangular detector array, which greatly reduces the conventional laser radar in the detection of the cable blind area. By simulating the actual detection state of...

Beschreibung
Zusammenfassung:	A high-resolution helicopter cable obstacle avoidance LIDAR is designed by the laser parallel scanning method, combined with the 3 × 2 rectangular detector array, which greatly reduces the conventional laser radar in the detection of the cable blind area. By simulating the actual detection state of helicopter through the UAV hanging-off test, the cable at 150 m is clearly detected at the data refresh rate of 2 Hz. Through the range detection test, it is verified that the detection distance of the system for φ 20 cable is more than 283 m.
