System for detecting whether automobile safety belt is worn correctly and detection method of system

Abstract

The invention discloses a system for detecting whether an automobile safety belt is worn correctly. The system for detecting whether the automobile safety belt is worn correctly is characterized in that the detection system comprises an image acquisition unit, an image processing unit and an alarm unit. The image acquisition unit is used for acquiring and then sending the image of the safety belt on a driver to the image processing unit; the image processing unit is used for judging the image of the safety belt; the alarm unit is controlled to perform sound-light alarming. As the structure is adopted, through detecting the angle of the line segment at the area of the driver and searching the line segment feature of the safety belt meeting wearing conditions, a judgment is made according to the type of the feature line segment, the wearing method of the safety belt can be effectively identified, and detection errors caused by incorrect wearing of the safety belt by the driver are overcome.

Description

technical field [0001] The invention relates to the use detection of automobile safety belts, in particular to a detection system and detection method for correct wearing of automobile safety belts. Background technique [0002] As the most effective safety protection device in the car, the seat belt binds the driver on the seat when the car brakes suddenly, preventing or reducing the driver's injury from secondary collision. When a dangerous situation occurs, the correct wearing of seat belts can greatly reduce the casualty rate. However, for various reasons, drivers do not wear seat belts or do not wear seat belts correctly from time to time. [0003] At present, the main way of detecting seat belt wearing is to install a buckle sensor at the seat belt slot. After the car is started, the seat belt is not buckled into the slot, and the detection system will issue a prompt. However, the driver still has incorrect wearing behaviors that make the detection invalid during dri...

AI Technical Summary

Problems solved by technology

However, the driver still has incorrect wearing behaviors that make the detection invalid during driving. There are three main types: 1. Do not wear a seat belt, and use an independent buckle to replace the seat belt buckle and insert it into the slot; 2. When the seat is empty Fasten the seat belt on the back of the seat, and lean against the back when getting on the bus; 3.
