Photographing device-based vehicle appearance measuring method and device and equipment

Abstract

The invention discloses a photographing device-based vehicle appearance measuring method and device and equipment. The method comprises steps: a first camera calibrates a photographing position; a second camera calibrates the photographing position; first photographing information is obtained when the first camera photographs the vehicle; second photographing information is obtained when the second camera photographs the vehicle; the first camera calculates and obtains the size information of the side of the vehicle, the front outer side of the vehicle and the rear outer side of the vehicle based on the first obtained photographing information; and the second camera calculates and obtains the size information of the side of the vehicle, front and rear wheel diameters and the vehicle wheelbase based on the second obtained photographing information. Through the above mode, measurement on the vehicle appearance can be realized through two cameras, the occupied area is small, the effectiveutilization area of a parking lot is improved, the purchasing cost and the use and maintenance cost are low.

Description

technical field [0001] The invention relates to the technical field of vehicle appearance measurement, in particular to a camera-based vehicle appearance measurement method, device and equipment. Background technique [0002] The handover room 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] See figure 1 , figure 1 It is a schematic diagram of the existing handover room using four laser radars to measure the appearance of the vehicle. like figure 1 As shown, the existing handover room uses four laser radars to measure the appearance of the vehicle, and the existing handover room uses four laser rada...

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
