Problems solved by technology
The disadvantage of this solution is that although several sensors are installed, the problem of false seat belt fastening is still not solved. For example, the "seat belt fitting sensor" detects the pressure on the seat belt buckle. If you sit on the seat belt , pulling by other actions will distort the sensor detection, and it is impossible to confirm whether the seat belt is fake

The invention discloses a device for preventing a seat belt from being tied spuriously and aims to solve the problem of identification in spurious tying of a seat belt in the prior art. The device comprises the seat belt, a seat belt lock catch, a lock catch sensor used for detecting that whether the lock catch is fastened or not, an image pick-up device used for shooting the wearing position of the seat belt on a driver or a passenger, an image pretreatment module used for carrying out denoising and contrast-enhancement on image frames, a seat belt identification module used for identifying that whether the passenger wears the seat belt correctly or not, and a processor used for data processing and input / output control; the lock catch sensor and the image pick-up device are connected with the processor; and the image pretreatment module and the seat belt identification module are arranged in the processor. The device can be extensively applied to occasions where seat belts are used.
Description
technical field [0001] The invention relates to an automobile auxiliary technology, in particular to a device for preventing false fastening of safety belts for automobiles. Background technique [0002] In order to prevent the car from causing serious injury to the occupants in the car due to emergency braking or collision accidents during driving, the car is equipped with a seat belt device. But in real life, many drivers and passengers are not aware of the important role of seat belts, and there are many phenomena of not wearing seat belts. For this reason, if you don’t fasten your seat belt, there will be a seat belt warning light and a voice prompt system on many cars to remind the front seat occupants to fasten their seat belts, but some people will buckle their seat belts but they don’t actually Put on the seat belt, so that the system will mistakenly think that the seat belt is fastened and no longer sound and light alarm, reminding the system to lose its effect, an...
