Laser radar device-based vehicle appearance measuring method, apparatus and device

Abstract

The invention discloses a laser radar device-based vehicle appearance measuring method, a laser radar device-based vehicle appearance measuring apparatus and a device. The method includes the following steps that: a laser radar device comprises a first bracket, a first laser radar, a second bracket and a second laser radar, wherein the first laser radar, based on a preset scanning radius inside aparking lot, automatically scans the information such as the width and length of a vehicle when the vehicle enters a scanning area corresponding to the scanning radius, so as to measure the width, length and other information of the vehicle, and the second laser radar automatically measures the information such as the wheel diameter and wheelbase of the vehicle when the vehicle enters the scanningarea corresponding to the scanning radius, so as to measure the wheel diameter, the wheelbase and other information of the vehicle. With the laser radar device-based vehicle appearance measuring method, the laser radar device-based vehicle appearance measuring apparatus and the device of the invention adopted, the measurement of the appearance of the vehicle can be realized by the two laser radars; a small area is just occupied, so that the effective utilization area of the parking lot is improved; and procurement costs and maintenance costs are low.

Description

technical field [0001] The present invention relates to the technical field of vehicle appearance measurement, in particular to a method, device and equipment for vehicle appearance measurement based on a laser radar device. Background technique [0002] The lidar handover room is a vehicle pick-and-place room in a large unmanned intelligent parking lot. It is used for automatic pick-and-place of cars by drivers, automatic pick-and-place of cars by parking robots, and automatic measurement of vehicle appearance information. The vehicle handover room between the field and the automatic measurement room for vehicle appearance information. [0003] See figure 1 , figure 1 It is a schematic diagram of using four laser radars to measure the appearance of vehicles in the existing laser radar handover room. Such as figure 1 As shown, the existing laser radar handover room uses four laser radars to measure the appearance of the vehicle, and the existing laser radar handover room...

AI Technical Summary

Problems solved by technology

[0005] The existing scheme of using four laser radars to measure the appearance of the vehicle, the four laser radars are arranged at the four corners of the vehicle placement area, because the distance between the laser radar and the measured vehicle is relatively large, the area occupied by the four laser radars is relatively small. large, which reduces the effective use area of ​​the parking lot. At the same time, the purchase cost of the four laser radars is relatively high, and the maintenance cost is relatively high
