A New Design of the Vehicle Detection System for Measuring Outline Size

Abstract

Vehicle dimensions parameters is an important part of vehicle trafficability parameters and vehicle operation safety testing. In order to measure the dimension parameters accurately, a new vehicle dimensions detection system which based on laser screen, ultrasonic sensor, and upper-computer control software is designed. It designs and debugs the system's hardware and software, and sets up test line, and the developed system is verified. Experimental results show that the system can detect the different models of vehicle dimensions with high accuracy, non-contact, automated testing, have the characteristic of stabilization, credibility, and error of calculation is lower than 1%.It solves the problem of high intensity of labor, inefficiency, and human error, which caused by China's vehicle testing institution to test vehicle outline dimension manually.
