[0002] Lidar is an active detection technology that can accurately and quickly obtain the three-dimensional spatial information of a target. It has unique technical advantages in target recognition, classification, high-precision three-dimensional imaging and measurement, and has a very broad application scope and development prospect. At present, the application of lidar has developed from the ground to the air, from the air to space, from land to the sea surface, from the sea surface to underwater, and involves multiple disciplinary fields.

[0003] Imaging lidar is a new technological product integrating multiple technologies such as laser technology, radar technology, optical scanning, control technology, high-sensitivity detection technology, and high-speed computer processing technology. As an important part of the imaging system, the imaging lidar device requires a compact, light, and convenient installation structure.

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. According to the following description, the purpose, technical solutions and advantages of the present invention will become clearer. It should be noted that the described embodiments are preferred embodiments of the present invention, rather than all embodiments.

[0020] Combination Figure 1 and Figure 2 As shown, an imaging laser radar installation structure includes a base plate 12, a motor fixing frame 5 vertically fixed on the base plate 12, and an L-shaped radar mounting bracket 10. In order to ensure that the motor mounting surface is perpendicular to the fixing frame plane and reduce processing costs, the base plate 12 and the motor fixing frame 5 are integrally processed and formed.

[0021] One side of the motor fixing bracket 5 is provided with a hollow servo motor 6. A conductive slip ring 13 is installed in the hollow position of the servo motor 6. A positioning groove 3 is formed in the middle of the bottom plate 12, and a navigation gyroscope 4 is installed in the positioning groove 3. The top end of the motor fixing bracket 5 is fixedly connected with a motor control mounting plate 8, and a motor control board 9 is installed on the motor control mounting plate 8. A positioning card slot 2 is formed in the horizontal section of the radar mounting bracket 10, and the lidar 1 is installed in the positioning card slot 2. The vertical section of the radar mounting bracket 10 is coaxially installed on the end face of the servo motor 6. The servo motor 6 is provided with a wire outlet 7 on one side of the tail end for outputting motor control cables.

[0022] A cable hole 10a is formed in the vertical section of the radar mounting bracket 10, and the cable 11 of the lidar 1 passes through the central hole 6a of the servo motor and is connected to the outer ring of the conductive slip ring 13. The radar mounting bracket is installed on the end face of the servo motor. When the servo motor works, it rotates together with the outer ring of the conductive slip ring. The cable of the lidar, the lidar and the radar mounting bracket rotate together without entanglement, and the conduction and signal transmission are stable.
