Vehicle appearance measurement method based on laser radar device, laser radar device and equipment

Abstract

The invention discloses a vehicle appearance measurement method and device based on a laser radar device, the laser radar device and equipment. The method comprises that the laser radar device comprises a single laser radar, a linear motion mechanism and a swinging mechanism; the single laser radar achieves measurement on the side part of a vehicle and the front and rear treads and the wheel baseof the vehicle through moving on the linear motion mechanism, wherein the side part of the vehicle indicates the length of the vehicle; the singe laser radar achieves measurement on the outer side ofthe front part of the vehicle and the outer side of the rear part of the vehicle via swinging of the swinging mechanism, wherein the outer side of the front part of the vehicle indicates the width ofthe front part of the vehicle, and the outer side of the rear part of the vehicle indicates the width of the rear part of the vehicle. According to the abovementioned mode, the vehicle appearance canbe measured via the single laser radar, the occupied area is small, the effective utilization area of the parking lot is improved, and meanwhile the purchase cost and operational maintenance cost arerelatively 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
