Abstract

The invention provides a safety belt detection method based on a monitor image. The method comprises the steps that the monitor image to be detected is acquired; a license plate in the image is identified, and the position area of the driver of a vehicle is determined according to the position of the license plate; the image of the position area of the driver is intercepted; and whether the intercepted image contains a safety belt image is detected. According to the invention, image identifying and analyzing are carried out on the area of the driver of the vehicle in the monitor video image; the scope of image identifying and analyzing is narrowed; the detection efficiency of the wearing state of a safety belt can be effectively improved; after grey processing is carried out on the video monitor image, a line corresponding to a safety belt edge image is detected; the image quality requirement of the monitor video image is reduced; monitor images of different pixel sizes and definition can be accurately detected; and the general applicability of the scheme is enhanced.

Description

technical field [0001] The invention relates to the technical field of image recognition and pattern recognition, in particular to a safety belt detection method based on a monitoring image. Background technique [0002] With the rapid development of society and economy, people's material living standards have been continuously improved. At the same time, the automobile industry has grown rapidly. More and more families choose cars as a means of transportation and travel. While providing people with comfortable and convenient travel options, There are also accidents and potential safety hazards caused by drivers or passengers violating road traffic regulations. [0003] Whether to wear seat belts during vehicle driving is directly related to the safety of the driver and passengers. When a collision occurs, the seat belt can fix the driver and passengers within a certain space around the vehicle seat, so as to avoid accidents caused by loss of control of the body and the safe...
