Truck side guard rail mounting size measurement system and method based on machine vision technology

Abstract

The invention relates to a truck side guard rail mounting size measurement system and a method based on a machine vision technology, so as to solve problems that as the truck guard rail is detected manually in the prior art, random errors such as a reading error and an environment error exist, the measurement result is influenced, and the measurement efficiency is low. The system comprises a ranging module, a graph acquisition module and a graph processing module, wherein the graph acquisition module comprises a camera unit, the ranging module is connected with the camera unit, the graph processing module comprises an image information processing unit, and the camera unit is connected with the image information processing unit. The system acquires two-dimensional image information of the side surface of the truck via the image acquisition module, the image is analyzed and processed via the image processing module, and mounting size information of the truck side guard rail is obtained. The system and the method of the invention have the advantages that a truck side guard device does not need to be touched, the mounting size of the truck side guard device can be quickly and effectively measured, and the detection efficiency is higher.

Description

technical field [0001] The invention relates to a detection technology for a truck guardrail, in particular to a system and method for measuring the installation size of a truck side guardrail based on machine vision technology. Background technique [0002] The truck body is long, and the driver in the cab has a blind spot. If a traffic accident occurs during driving, it is easy to cause cars, battery cars, motorcycles, etc. to get into the bottom of the truck or pedestrians are scratched and involved in the bottom of the car, causing injuries. even death. The truck has a high rigidity and a large mass. When other objects, including battery cars and motorcycles, hit it, the truck itself and its driver will suffer minor injuries, but the other party will suffer more serious injuries. As a preventive measure, the state issued the national standard (GB7258-2004) of "Technical Conditions for Motor Vehicle Operation Safety" in 2004. For trucks and trailers with a total mass gre...
