Method for measuring outer contour size of static laser scanning vehicle

Abstract

The invention discloses a method for measuring an outer contour size of a static laser scanning vehicle. A back bracket, a back rail group fixed to the back bracket, a back laser ranging scanner installed in a back rail car, a back rail car installed on a back rail group, a front laser ranging scanner installed in a front rail car, a front rail car installed on a front rail group, a front rail group fixed to a front bracket, the front bracket, a right limit block, a front limit block, a network camera, an LED lattice screen and a touch control integrated machine are included, maximum value and minimum value sequences and maximum values and minimum values of the corresponding sequences are obtained through calculation, and thus the height, width and length of the outer contour of a vehicle to be measured are accurately calculated. According to the method, the fully automatic, non-contact and dynamic through type measurement has high efficiency, the data of length, width and height of the vehicle, a gate height and a cargo compartment size can be quickly measured, and the data and vehicle standard data can be subjected to automatic comparison and judgment.

Description

technical field [0001] The invention belongs to the field of a method for measuring the outer contour of a vehicle, in particular to a method for measuring the outer contour size of a vehicle by static laser scanning. Background technique [0002] Motor vehicles have become one of the indispensable means of transportation in the current society. However, in order to obtain greater economic benefits, some vehicle users who are used for cargo / passenger transportation increase the vehicle volume by modifying the size of the vehicle to reach the one-time transportation volume of the vehicle. The purpose is to reduce transportation costs. However, this measure seriously violates the safety standards for vehicle use and exceeds the national standards, especially for vehicles that are longer and wider. . Therefore, in order to ensure the safety of the vehicle and maintain the country's regulations on "trucks, trailers, and passenger cars with a length of more than 6 meters, the ve...

AI Technical Summary

Problems solved by technology

[0004] (1) The side and corner information of the subject cannot be displayed, or the corners of the captured object are inaccurate and there are errors, and the error will be greater when encountering non-right angles and non-straight sides;

[0005] (2) The darkest and brightest parts of the subject are blurred and cannot get a complete image, which is greatly affected by weather and light;

[0006] (3) It cannot be applied to indoor measurement. Small trucks are about 4 meters, general trucks are about 10-16 meters, and large trucks are about 21 meters. If the measurement camera cannot be reasonably configured, all the measured objects will be in the measurement formed by the camera. In the field, it is impossible to completely measure the length, width and height parameters of the vehicle under test;

[0007] (4) Occupies too much space, not suitable for small testing stations
