Safety belt detection method and device

Abstract

The invention provides a safety belt detection method and device. The method comprises the following steps: acquiring a driving image within a preset time period; acquiring a safety belt mask based on each frame of driving image, and judging whether two boundaries of the safety belt are parallel or not based on the safety belt mask to obtain a parallel judgment result; segmenting the safety belt mask to obtain a first safety belt and a second safety belt corresponding to each frame of driving image; judging whether the first safety belt and the second safety belt are coherent to obtain a coherent judgment result; according to the parallel judgment result and the coherence judgment result, obtaining a safety belt wearing judgment result of each frame of driving image; and generating and sending alarm information when the sum of the safety belt wearing judgment results of the driving images is greater than a first preset threshold value. Whether the effective safety belt exists in the corresponding driving image or not is determined by judging the boundary parallelism of the safety belt in the driving image and judging the coherence of the first safety belt and the second safety belt, so that the safety belt detection precision is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a safety belt detection method and device. 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 and rapid growth of automobiles has brought a huge burden to the urban traffic system. Illegal driving and bad driving behaviors still exist. Drivers who do not wear seat belts are directly related to the safety of themselves and others. Seat belt detection is an important part of vehicle violation detection in the field of intelligent transportation, which can effectively help traffic law enforcement officers to supervise the behavior of drivers wearing seat belts. [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. Wh...

[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
