Embodiment 1

[0027] 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 ground in the middle of the parking space; the device includes a track 4 parallel to the long side of the parking space, on which a laser radar 1 and a displacement sensor 2 that can slide simultaneously are provided, the described The laser radar 1 is mounted on a slide block 3 that can slide along the track; the testing direction of the laser radar 1 is perpendicular to the track 4 .

[0028] 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:

[0029] S1: Raise or turn on the lidar and displacement sensor, make the lidar protrude from the ground, slide the slider to one end of the track, and record it as the zero point of displacement;

[0030] S2: Start the lidar and displacement sensor...

Abstract

The invention relates to the technical field of vehicle appearance measurement, and in particular relates to a device and a method for measuring a vehicle axle distance based on a laser radar. The device is installed on the ground in the middle of a parking space. The device comprises a rail parallel to the long side of the parking space, a laser radar and a displacement sensor which can slide simultaneously are arranged on the rail, and the laser radar and the displacement sensor are installed on a sliding block capable of sliding along the rail in a liftable or foldable mode. The test direction of the laser radar is perpendicular to the rail. The device is simple in structure and convenient to manufacture, does not need to be installed on stand columns or ceilings or roller shutter doorsor other external structures, and does not hinder the periphery of the parking space. The hidden structure is arranged, the whole device can be hidden under the ground, and vehicles, users and parking robots are not hindered; the axle distance is calculated through the Pythagorean theorem, parking spaces are not required to be parallel to parking spaces, the precision is high, and errors are small.

Description

technical field [0001] The invention relates to the technical field of vehicle appearance measurement, in particular to a laser radar-based device and method for measuring vehicle wheelbase. 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 who use smart parking lots, the ...
