A vision-based safety belt detection method and system

Abstract

The invention discloses a vision-based safety belt detection method and system. The vision-based safety belt detection method comprises the following steps: acquiring primary driver / co-driver picture data; performing human body key point detection on the main driving / co-driving picture data, determining the positions of human body key points, and the human body key points being the shoulders and the waist; carrying out expansion matting on the key point positions of the human body to obtain a matted picture; and inputting the matted picture into a pre-trained deep neural network to classify whether the safety belt is fastened or not, if the classification is that the safety belt is not fastened, giving an alarm, otherwise, not giving an alarm. The invention has the advantages that the human body key point detection technology is used for detecting key points of the upper limbs, the shoulders and the waist of the human body, then the deep learning classification network is used for classifying the matted image areas to judge whether the safety belt is fastened or not, and the technical scheme of the invention enables the safety belt detection to be obviously improved in detection precision and recall.

Description

technical field [0001] The invention relates to a vision-based safety belt detection method and system, belonging to the technical field of vision detection. Background technique [0002] With the development of the economy, the speed of urban construction is accelerating, and the number of cars is increasing year by year. The continuous increase in the number of cars has brought a huge burden to the urban traffic system. The existence of illegal driving and bad driving behaviors makes traffic safety particularly important. Drivers who do not wear seat belts are directly related to the safety of themselves and others. [0003] The traditional seat belt detection is triggered by the contact switch inside the buckle. When the driver enters the cab and turns on the ignition key, the controller starts to work. When the seat belt is not inserted into the buckle, the circuit of the car seat belt sound prompt device is turned on to remind the driver After wearing the seat belt, th...

[0004] However, since the detection system is only aimed at the inside of the buckle, there are certain limitations. The driver can shield the seat belt prompt by using the seat belt buckle, or directly inserting the seat belt into the buckle from the back, so that the driver can block the seat belt prompt when the safety belt is not fastened. driving with
