Description

Technical Field

[0001] The utility model relates to the technical field of laser radar, and in particular to a 360-degree rotating laser radar three-dimensional scanning device. Background Art

[0002] With the rapid development of laser technology, the application of laser radar is becoming more and more extensive. In particular, laser radar has the advantages of high resolution, good stability, strong anti-interference ability, no light influence, small size, light weight, etc., and more and more applications in various industries rely on laser radar. In addition to many two-dimensional applications, there are also many demands for three-dimensional applications of laser radar. The internal structure of the three-dimensional laser radar itself is relatively complex, and the program development is also relatively cumbersome, which leads to an increase in R&D costs and a longer R&D cycle; the three-dimensional application of two-dimensional laser radar solves the above problems very well, and the structure is very stable, which quickly turns the two-dimensional data collected by the two-dimensional laser radar into three-dimensional data, greatly reducing the development cycle of the three-dimensional radar. At present, there are some similar three-dimensional applications of two-dimensional laser radar on the market, but they all have shortcomings, mainly caused by the instability of the structure, which makes the collected data have a large deviation, and the rotation angle is limited, and it cannot rotate 360° for scanning, and the collected data is not comprehensive enough and has poor accuracy. Utility Model Content

[0003] In view of the above problems, the utility model provides a 360° rotating laser radar three-dimensional scanning device. The innovative structural improvement enables it to have the function of 360° rotating space scanning, and the data collection is more comprehensive. It has the advantages of low environmental conditions and high recognition accuracy.

[0004] A 360° rotating laser radar three-dimensional scanning device, comprising: a laser radar, a servo drive motor, a control unit, a slip ring structure and a housing support structure, wherein:

[0005] The cube-shaped shell support structure is composed of a lower base, an upper cover and a bracket connected by screws, and the laser radar, servo drive motor, control unit and slip ring structure are integrated and installed on the shell support structure; the servo drive motor and control unit are built into the closed cavity of the shell support structure; the laser radar and the slip ring structure are installed on the bracket of the shell support structure through the transmission shaft; the control unit controls the start, stop and rotation of the servo drive motor, and the laser radar is connected to the servo drive motor through the bracket and the transmission shaft so that the servo drive motor drives the laser radar to rotate; the control unit is connected to the laser radar through cables to transmit data and power supply, so that the laser radar can scan the outside and collect data; the slip ring structure plays a role in connecting and converting the cables of the laser radar and the control unit so that the connecting cables will not be entangled and locked when the laser radar rotates 360°.

[0006] The servo drive motor is a high-precision servo motor. Through the instructions issued by the control unit, the connection shaft can be controlled to rotate 360° forward and backward, and can be stopped and started at any position; and the rotation angle and speed can be controlled to realize the laser radar scanning at any position. The control unit mainly supplies power and data to the servo drive motor and the laser radar through cables, controls the start and stop rotation of the servo motor by sending instructions, controls the rotation angle and speed; and receives the scanning data from the laser radar and uploads it to the host computer for analysis. The slip ring structure is nested on the connecting shaft, and its main function is to convert the connecting cable between the control unit and the laser radar; when the servo motor drives the laser radar to rotate through the connecting shaft and the bracket, it will drive the connected cable to rotate, thereby generating entanglement, causing the cable to be strangled and broken. The slip ring structure ensures that the cable can rotate normally when the laser radar rotates through the structure of its own stator and rotor, and the cable will not be entangled and broken, ensuring the smooth flow of power supply and data. The laser radar can achieve 360° rotational spatial scanning through the drive of the servo drive motor; the laser radar itself is a two-dimensional scanning plane, and three-dimensional space scanning is achieved by driving the overall rotation of the laser radar, so that the volume data of some spaces can be measured and transmitted to the control unit and host computer through cables for analysis.
