Embodiment 1

[0050] The bracket device of this embodiment, such as Figure 1 to Figure 7 As shown, it includes a displacement assembly 1, a turning mechanism 3 and a lifting mechanism 4, wherein the displacement assembly 1 is arranged on the roof (not shown), and includes at least one mounting base 2 that can move relative to the roof surface; the turning mechanism 3 is provided On the installation base 2, it can turn over and rotate relative to the roof surface; the lifting mechanism 4 is fixed on the turning mechanism 3, and has a moving end that can move up and down relative to the roof surface.

[0051] The support device of the above structure is composed of a displacement assembly 1, an overturning mechanism 3 and a lifting mechanism 4. The displacement assembly 1 is set to move in a straight line in a direction parallel to the roof surface, and the overturning mechanism 3 is set to realize relative to the roof. The flipping and turning of the surface makes the vertical movement of t...

Embodiment 2

[0062] The laser radar calibration device provided in this embodiment includes at least one laser radar calibration structure 5 and the bracket device of embodiment 1, and the laser radar calibration structures are fixed on the mobile terminal in one-to-one correspondence.

[0063] Since the laser radar calibration structure 5 is arranged on the above-mentioned support device, the laser radar calibration structure 5 can move along the X-axis direction, the linear movement along the Y-axis direction, the linear movement along the Z-axis direction, and the vertical movement along the Z-axis direction along with the support device. The rotation movement in the X-axis direction and the rotation movement around the Y-axis direction enable the lidar calibration structure to move in five degrees of freedom, with more degrees of freedom, a wider range of calibration, more comprehensive image data, and less development. The installation and debugging of personnel can quickly realize the...

Abstract

The invention belongs to the technical field of laser radar mounting brackets, and in particular relates to a bracket device and a laser radar calibration device, wherein the bracket device includes a displacement component, is arranged on the roof of the vehicle, and includes at least one installation base that can move relative to the roof surface of the vehicle; a turning mechanism The lifting mechanism is fixed on the turning mechanism and has a movable end that can move up and down relative to the roof surface. The setting of the displacement component realizes the linear movement in the direction parallel to the roof surface, the overturning rotation relative to the roof surface is realized by the setting of the turning mechanism, and the vertical movement relative to the roof surface is performed by the lifting mechanism, and the freedom of movement is It is higher and has a larger adjustment range; at the same time, the cooperation of the displacement component, the turning mechanism and the lifting mechanism is realized through the installation base, and the integration degree is higher, so as to solve the problems of limited freedom and small adjustment range of the existing bracket device in the background technology.

Description

technical field [0001] The invention belongs to the technical field of laser radar mounting brackets, and in particular relates to a bracket device and a laser radar calibration device. Background technique [0002] Lidar has been widely used in various fields due to its measurement advantages such as high precision and high resolution. For example, in the field of self-driving car testing, the roof lidar of the vehicle to be tested is used to calibrate the roof of the vehicle to be tested to obtain image data with the roof of the measured vehicle, so that developers can complete the test of the roof. [0003] At present, the existing roof lidar equipment is fixedly installed on the roof after being calibrated and calibrated. Usually, the roof lidar equipment mainly includes a bracket device and a lidar calibration structure set on the bracket device. Due to different car series There are differences in the size of the roof between different vehicles of the same car series ...
