Example Embodiment

[0037] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further explained in conjunction with specific drawings.

[0038] See figure 1 , Which shows the flow chart of the safety belt detection method in the present invention. The detection method is based on image analysis technology and mainly includes the following steps:

[0039] Step 1. First, accurately locate the window area in the obtained image. For precise positioning of the window area, genetic algorithm-based methods and fast window positioning algorithms based on the average color difference can be used. Of course, vehicle type recognition can also be performed first, and the window position can be constrained based on the prior knowledge of the window positions of different models , But not limited to the methods listed.

[0040] After precise positioning of the window area, for the convenience of subsequent operat...

Abstract

The invention discloses a vehicle safety belt detection method and device based on image analysis. The vehicle safety belt detection method and device based on image analysis is applied to the image analysis field of intelligent transportation. Firstly, a vehicle widow area is positioned; the position of a safety belt is detected primarily through a line segment detection method; the safety belt is accurately positioned according to the angle and the length of the line segment. The vehicle safety belt detection method and device based on image analysis can store the information of vehicles with passengers not belted up, and provide sufficient, reliable and strict evidences for detection of the traffic offence of not fastening the safety belt.

Description

Technical field [0001] The present invention relates to the field of image analysis technology, in particular to image analysis technology in intelligent transportation. Background technique [0002] Safety is the most basic requirement for people to travel. Some people also pay great attention to the safety performance of the vehicle when buying a car, but they do not pay enough attention to the safety belt that protects the lives of drivers and passengers. When a high-speed car collides or encounters an unexpected emergency braking, a huge inertial force will be generated. This inertial force may exceed 20 times the weight of the driver, causing the driver and passengers to interact with the steering wheel, windshield, and The collision of seat backs, doors and other objects can easily cause injuries to the drivers and passengers, and even throw the drivers off the seat or out of the car. [0003] The role of car seat belts is that when a vehicle collides or uses emergency brak...
