Problems solved by technology

However, due to the low performance of the selected operating platform and the unreasonable detection algorithm used, the accuracy of non-seat belt detection is not high. It still requires a lot of manual secondary screening, and the detection efficiency is very low.

Embodiment Construction

[0051] Such as figure 1 As shown, a detection method for motor vehicle drivers and occupants not wearing seat belts on the way includes the following steps:

[0052] (1) Read the captured motor vehicle pictures and related information from the existing road video surveillance system; decode and store the read motor vehicle pictures in BMP bitmap file format;

[0053] (2) Select four non-overlapping area images with a size of 100×100 pixels at the four corners of the stored motor vehicle picture, and use the multi-scale edge intensity change and direction statistical distribution algorithm to determine whether the four area images are blurred. If If there are no less than two areas in a picture of a motor vehicle that are blurred, it is determined that the picture of the motor vehicle is blurred, and the blurred picture is selected and eliminated;

[0054] (3) Detect the position of the front glass window of the motor vehicle and the position of the license plate in the clear ...

Abstract

The invention provides a method for detecting whether drivers and passengers of motor vehicles fasten seat belts on the way. The method comprises: reading captured motor vehicle images and decoding the motor vehicle images into BMP bitmaps; eliminating fuzzy images; detecting positions of front glass windows of motor vehicles to determine cab positions, and calculating the cab positions by means of license plate positions; detecting drivers, passengers and seat belts in the cab areas; judging whether the drivers and the passengers fasten the seat belts; carrying out histogram equalization image enhancement processing of the parts where the seat belts are judged as unfastened, and performing storage operation. The invention comprehensively adopts many computer image processing algorithms to improve the detection efficiency and accuracy on the premise of guaranteeing the precision, and also makes it possible to detect at the same time whether drivers and passengers all fasten seat belts.

Description

technical field [0001] The invention relates to a road traffic order monitoring and management system, in particular to a detection method for motor vehicle drivers and passengers not wearing safety belts on the way. Background technique [0002] Road traffic accidents have brought great harm to people's lives and property, causing more than 100,000 deaths per year; when a traffic accident occurs, the time from the collision of the vehicle to the collision between the driver and the occupant and the object in the vehicle is only 0.2 seconds, and the human reaction time is generally more than 0.3 seconds, so drivers and passengers can only rely on safety belts to protect themselves. Statistics show that wearing a seat belt can reduce the death rate by 57% in a frontal collision of a motor vehicle; wearing a seat belt can reduce the death rate by 44% in a side collision; and wearing a seat belt can reduce the death rate by 80% in the event of a rollover %. However, many dr...
