System and method for measuring length or width or height of vehicles in real time

Abstract

The invention provides a system for measuring the length or the width or the height of vehicles in real time. The system is high in measuring speed, free of manual work, low in cost, high in measuring precision and high in safety performance. The system comprises a first laser scanner 1, a second laser scanner 2, a controller, a server and a vehicle data real-time management system. The first laser scanner 1 is supported through a first support 3, the second laser scanner 2 is supported through a second support 4, and a sentry box of an entrance or an exit of a store is arranged between the two laser scanners. While the vehicles are stopped for making a record and paying, the system can immediately measure the length of the vehicles in real time at the same time. According to the characteristics of different laser scanners, the measuring time of the system is only 0.1 to 1 second, and the measuring precision can reach several millimeters or dozens of millimeters. The invention also provides a measuring method based on the system at the same time.

Description

technical field [0001] The invention relates to a system and method for measuring vehicle length, width or height in real time. Background technique [0002] At present, as food safety issues are getting more and more attention, the wholesale of agricultural products is gradually concentrated in large-scale stores with features such as pesticide residues, trace element detection, and standardized management. However, unlike common materials that are billed by weighing scales, agricultural product transactions have their own special features. For example, watermelons are heavy in weight but low in value, and the traders’ profits are also low. In this case, if according to Billing by weighbridges will gradually give up the trading of heavier and less profitable agricultural products in the store, which is not conducive to the diversification of agricultural products traded in the store. Therefore, in the agricultural product trading market, most of the entry transaction fees ...

Problems solved by technology

There are following disadvantages in this way: 1, the speed is slow

When there are many cars at night, they will wait in line for measurement, and even block the roads outside the store during peak hours, affecting urban road traffic; and drivers need to queue for a long time to enter the store, which consumes a lot of time for the driver, and secondly, it takes a lot of time for the d
