Description

Technical Field

[0001] This utility model relates to the field of lidar technology, and in particular to a lidar stabilizing gimbal. Background Technology

[0002] With the rapid development of technologies such as autonomous driving, robot navigation, and terrain mapping, LiDAR, as a high-precision environmental perception device, is widely used in various intelligent systems. LiDAR is usually mounted on a pan-tilt unit to achieve multi-angle scanning and data acquisition. However, in practical applications, LiDAR systems often face interference factors from the external environment, such as vibration and impact. Especially when operating on mobile platforms (such as unmanned vehicles and drones), these interferences can seriously affect the measurement accuracy and data stability of the radar.

[0003] Existing lidar gimbal structures are mostly rigidly connected and lack effective shock absorption mechanisms, which makes the lidar prone to displacement or jitter when subjected to vibration, thus affecting the clarity of the scanned image and the accuracy of the data. Therefore, this utility model proposes a lidar stabilizing gimbal to solve the above problems. Utility Model Content
