Embodiment 1

[0043] This embodiment relates to a device for measuring the wheelbase of a vehicle based on laser radar, such as figure 1 As shown, the device is installed on the parking robot; the device includes a track 3 installed on the main body of the parking robot parallel to the ground, and a laser radar 1 and a displacement sensor 2 that can slide simultaneously are arranged on the track 3 , the lidar 1 and the displacement sensor 2 slide on the track 3 through the slider 4; the testing direction of the lidar 1 is perpendicular to the track 3.

[0044] The method of measuring the vehicle wheelbase using the laser radar-based measuring vehicle wheelbase device in this embodiment, such as figure 2 As shown, the method includes:

[0045] S1: Slide the lidar and displacement sensor to one end of the track, and record it as the zero point of displacement;

[0046] S2: Start the lidar and displacement sensor, and drive the lidar and displacement sensor to slide, record the time, distan...

Abstract

The invention relates to the technical field of vehicle appearance measurement and parking robots, and discloses a device and method for measuring the axle distance of a parking robot based on a laserradar. The device is installed on a parking robot. The device comprises a track which is installed on a parking robot body and is parallel to the ground, a laser radar and a displacement sensor whichcan slide at the same time are arranged on the track, and the laser radar and the displacement sensor slide on the track through sliding blocks. The test direction of the laser radar is perpendicularto the track. The device is simple in structure and convenient to manufacture, does not need to be installed on stand columns or ceilings or roller shutter doors or other external structures, and cannot hinder the periphery of the parking space. The device is directly installed on the parking robot, does not interfere with vehicles, users and the parking robot, does not need to build a large structure or equipment, and does not need to greatly modify the ground. The axle distance is calculated through the Pythagorean theorem, the vehicle is not required to be parallel to the parking robot, precision is high, and errors are small.

Description

technical field [0001] The invention relates to the technical field of vehicle appearance measurement and parking robot, in particular to a device and method for measuring wheelbase of a parking robot based on laser radar. Background technique [0002] The parking hall is the vehicle pick-and-place room of a large unmanned intelligent parking lot. It is used for automatic pick-and-place of vehicles by drivers, automatic pick-and-place of vehicles by parking robots, and automatic measurement of vehicle appearance information. It is the link between drivers and intelligent parking lots. The vehicle handover room and the automatic measurement room for vehicle appearance information. [0003] Existing parking halls generally have peripheral structures such as columns, ceilings, and rolling doors. Measuring devices such as laser radar ranging devices and camera ranging devices are installed on these peripheral structures to measure the appearance of vehicles. However, for users ...
