The base 100, the supporting piece 200 and the mounting seat 400 enclose a protection space for protecting the laser radar 500, the laser radar 500 is positioned between the base 100 and the mounting seat 400, one side of the laser radar 500 is the supporting piece 200, and the other side of the laser radar 500 is free from shielding, can emit laser beams and receive echo signals, and achieves a distance measurement function.
In some embodiments, the rotary drive 300 is a motor, rotary cylinder, or rotary cylinder.
Alternatively, the rotary drive 300 is a servo bi-directional motor.
In one embodiment, referring to fig. 3, the end of the supporting member 200 remote from the base 100 has a mounting groove 210, the rotary driving member 300 is mounted in the mounting groove 210, and the output end of the rotary driving member 300 protrudes from the mounting groove 210 and is connected to the mounting seat 400. The design of the mounting groove 210 plays a role in positioning and mounting the rotary driving member 300, ensures that the position of the rotary driving member 300 is stable, and further ensures that the rotary driving member 300 can stably control the mounting angles of the mounting seat 400 and the laser radar 500, and is used for accommodating the rotary driving member 300, so that the registration device is miniaturized.
In some embodiments, referring to fig. 3 and 4, the registration device further includes a controller 610 electrically connected to the rotary driving member 300 to control a rotation angle of the output shaft 310 of the rotary driving member 300. The controller 610 can control the rotation driving unit 300 to automatically adjust the mounting angles of the mounting base 400 and the lidar 500, thereby improving the automation level and the mounting efficiency of the lidar 500.
Specifically, the controller 610 is a single-chip microcomputer. The singlechip (Micro controller Unit; MCU) has small volume and light weight, and is convenient for the registration device to be installed outdoors.
Specifically, the controller 610 is detachably mounted on the base 100, so that on one hand, the controller 610 can be electrically connected with the rotary driving member 300 in a near place, which is convenient for wiring, and on the other hand, the position of the base 100 is relatively stable, which is beneficial for the controller 610 to operate stably.

In the illustrated embodiment, the recess is located on a side of the base 100 facing the mount 400. It will be appreciated that in other embodiments, the recess may be located on a side of the base 100 remote from the mount 400, or the recess may be located on one of the left and right sides of the base 100.
In particular, in connection with fig. 3 and 4, the registration device further comprises a gyroscope 620. The gyroscope 620 is used for detecting the horizontal angle of the mounting base 400, and the gyroscope 620 is electrically connected with the controller 610. In this way, the controller 610 obtains the current horizontal angles of the mounting seat 400 and the laser radar 500 through the gyroscope 620, and if the current horizontal angle of the mounting seat 400 does not conform to the preset mounting angle, the rotary driving piece 300 is controlled to rotate, and the mounting seat 400 is driven to rotate until the horizontal angles of the mounting seat 400 and the laser radar 500 conform to the preset mounting angle, so that automatic and efficient adjustment is realized.
For example, the lidar 500 is mounted on the mounting base 400, and the predetermined mounting angle of the lidar 500 is 0. At this time, if the gyroscope 620 measures that the horizontal angle of the mount 400 is +5°, the controller 610 controls the rotation driving member 300 to reversely rotate by 5 °, so that the mount angles of the mount 400 and the lidar 500 are adjusted to 0.
For another example, the lidar 500 is mounted on the mounting base 400, and the predetermined mounting angle of the lidar 500 is 0. At this time, if the gyroscope 620 measures that the horizontal angle of the mount 400 is-5 °, the controller 610 controls the rotation driving member 300 to rotate forward by 5 °, so that the mounting angles of the mount 400 and the lidar 500 are adjusted to 0.
For another example, the lidar 500 is mounted to the mount 400, and the predetermined mounting angle of the lidar 500 is-10 °. At this time, if the gyroscope 620 measures that the horizontal angle of the mount 400 is-5 °, the controller 610 controls the rotation driving member 300 to reversely rotate by 5 °, so that the mounting angles of the mount 400 and the lidar 500 are adjusted to-10 °.
Optionally, a gyroscope 620 is mounted to the base 100 such that the gyroscope 620 can be electrically connected to the controller 610. In the illustrated embodiment, gyroscope 620 is located on a side of base 100 facing mount 400 to facilitate angle detection of mount 400 by gyroscope 620.
It will be appreciated that in other embodiments, gyroscope 620 is mounted to mount 400, and the mounting angle of mount 400 can be measured directly. Of course, gyroscope 620 may alternatively be mounted to support 200, and is not limited in this regard.
In one embodiment, referring to fig. 3, the controller 610 is electrically connected to the lidar 500, and the lidar 500 is capable of acquiring a height difference between two preset reference points. The controller 610 directly uses the point cloud data of the lidar 500 to determine whether the lidar 500 is mounted in place, and if not, adjusts the mounting angle of the lidar 500 by rotating the driving member 300 until the mounting angle meets the preset mounting angle.
For example, the difference in height between the two preset reference points is actually 0. At this time, the laser radar 500 measures that the height difference between the two preset reference points is 10cm and the distance between the two preset reference points is 50cm, and then the controller 610 gradually controls the rotation of the rotation driving member 300 by the dichotomy, and firstly controls the rotation driving member 300 to reversely rotate by 1/2 of arcsin (10/50). After the rotation of the rotation driving part 300 is completed, the laser radar 500 again measures the height difference between the two preset reference points, and if the height difference is within the error range, the installation angle is adjusted. Otherwise, the height difference information is fed back to the controller 610, and the controller 610 records the current state information and again controls the rotation of the rotary driving member 300 until the height difference between the two preset reference points measured by the laser radar 500 is within the error range.
For another example, the difference in height between the two preset reference points is actually 0. At this time, the laser radar 500 measures that the difference in height between the two preset reference points is 10cm and the distance between the two preset reference points is 50cm, and the controller 610 controls the rotation driving member 300 to reversely rotate arcsin (10/50) in one step. After the rotation of the rotation driving part 300 is completed, the laser radar 500 again measures the height difference between the two preset reference points, and if the height difference is within the error range, the installation angle is adjusted. Otherwise, the height difference information is fed back to the controller 610, and the controller 610 records the current state information and again controls the rotation of the rotary driving member 300 until the height difference between the two preset reference points measured by the laser radar 500 is within the error range.
For another example, the difference in height between the two preset reference points is actually 10cm. At this time, the laser radar 500 measures that the difference in height between the two preset reference points is 15cm and the distance between the two preset reference points is 50cm, and the controller 610 controls the rotation driving member 300 to reversely rotate arcsin ((15-10)/50). After the rotation of the rotation driving part 300 is completed, the laser radar 500 again measures the height difference between the two preset reference points, and if the height difference is within the error range, the installation angle is adjusted. Otherwise, the height difference information is fed back to the controller 610, and the controller 610 records the current state information and again controls the rotation of the rotary driving member 300 until the height difference between the two preset reference points measured by the laser radar 500 is within the error range.
In one embodiment, in conjunction with fig. 3 and 4, the registration apparatus further includes a positioning module 630. The positioning module 630 is electrically connected to the controller 610, and the positioning module 630 is configured to obtain geographic location information of the lidar 500. The controller 610 can obtain and store current geographic location information of the lidar 500 via the positioning module 630. When the lidar 500 needs maintenance, a worker can accurately reach the position of the registration device for maintenance according to the geographical position information.
Optionally, the positioning module 630 is mounted on the base 100, so that the positioning module 630 is electrically connected to the controller 610.
In the illustrated embodiment, the positioning module 630 is mounted directly on the circuit board of the controller 610.
Optionally, the positioning module 630 is a GPS positioner or a beidou positioner.
In some embodiments, the controller 610 also has a communication module for communication with the outside, so that a worker can control the rotation of the rotary drive 300 remotely through the controller 610.
In some embodiments, the registration device further includes a lift drive (not shown) mounted to the base 100, the output of the lift drive being coupled to the support 200. The elevation driving member adjusts the elevation of the supporting member 200, thereby elevating the mounting base 400 and the laser radar 500, so that the laser radar 500 can meet the preset mounting height.
Alternatively, the elevation driving member is electrically connected to the controller 610, so that the controller 610 can automatically adjust the installation height of the lidar 500.
