Identification and pre-warning method of hazardous article conveying vehicle appearing in front of coach bus

Abstract

The invention relates to an identification and pre-warning method of a hazardous article conveying vehicle appearing in front of a coach bus and belongs to the technical field of automobile driving safety equipment. The method includes: building a small database of hazardous article tanks on the basis of the quasi-circular contour features of the hazardous article conveying vehicle in the vision field of a rear vehicle and the special character sign of the hazardous article conveying vehicle, wherein the database comprises a character part and an image part, and the image part is an image with the quasi-circular contour features; using a least square method to fit the shape contour and feature character of a front vehicle, and judging that the front vehicle is the hazardous article conveying vehicle and giving out a warning if the fit result is matched with the data in the database. The method has the advantages that the contour and special characters of the front vehicle are identified to judge whether the front vehicle is the hazardous article conveying vehicle or not so as to warn a driver, rear-end collision, caused by fatigue or inattention of the driver, with the hazardous article conveying vehicle is prevented, occurrence rate of traffic accidents is reduced greatly, and safety of people's lives and properties is guaranteed effectively.

Description

technical field [0001] The invention belongs to the technical field of automobile driving safety equipment, in particular to a method for hazard identification and early warning. Background technique [0002] With the continuous and rapid development of my country's economy and the increasing number of road transport vehicles, road transport vehicle accidents have shown an upward trend in recent years, especially reports on expressway accidents are common in various media. Most of the major vicious incidents were rear-end collisions between long-distance buses and vehicles transporting dangerous goods. Due to the fast speed of long-distance buses, the speed of dangerous goods transport vehicles is relatively slow, which may easily cause rear-end collision accidents. Judging from the similar accidents that have occurred, the occurrence of such accidents will cause vehicles to be scrapped, or even crashed, resulting in huge economic losses, heavy casualties, and serious pollu...
