A laser radar stabilization device

Abstract

The invention discloses a laser radar stabilizing apparatus, which comprises a stabilizing platform. The stabilizing platform comprises an intermediate shaft, the intermediate shaft is sleeved with aninner magnetic ring group. The outer side of the inner magnetic ring group is provided with a coil group, and a gap is formed between the inner magnetic ring group and the coil group. The outer sideof the coil group is provided with a retainer, and the lower end of the coil group is arranged on a step of the retainer. The upper end of the retainer is connected with an upper leaf spring, and thelower end of the retainer is connected with a lower leaf spring. The retainer is connected to outer rings of the upper leaf spring and the lower leaf spring by bolts, and inner rings of the upper leafspring and the lower leaf spring are connected to the intermediate shaft. The outside of the retainer is provided with a chassis, and the chassis is used for supporting the retainer. According to thelaser radar stabilizing apparatus, the electromagnetic force is controlled to cancel the restoring force of the upper leaf spring and the lower leaf spring in the vertical direction by arranging theinner magnetic ring group and the coil group, thereby achieving stabilizing control in the vertical direction.

Description

technical field [0001] The invention relates to the technical field of laser radar, in particular to a laser radar stabilization device. Background technique [0002] LiDAR uses laser to scan the surrounding environment in 3D, which plays an irreplaceable role in the fields of automatic driving and high-definition maps. The traditional laser radar is installed on the carrier platform through a fixed bracket. The vibration of the carrier platform directly causes the pose of the radar to change, reducing the resolution and accuracy of the laser radar, which makes the data measured by the laser radar a lot of noise. Contents of the invention [0003] The object of the present invention is to provide a laser radar stabilization device to solve the above-mentioned problems in the prior art, so as to enable the laser radar to achieve vertical stability control and reduce measurement data noise. [0004] To achieve the above object, the present invention provides the following s...
