Technical Field
The invention belongs to the technical field of vehicles, and particularly relates to a safety belt monitoring system, a vehicle, a safety belt monitoring method and a storage medium.
Background
The vehicles are more and more popularized, an average family has at least one vehicle, even a plurality of vehicles, the road traffic environment in each large and medium-sized city is gradually complicated, traffic accidents frequently occur, according to incomplete statistics, when accidents occur during riding, the death rate is reduced by more than 50%, and the disability rate caused by injuries is reduced by more than 70%. The safety belt is a device for preventing the body movement of a driver and a passenger from secondary collision in an emergency so as to reduce the damage result of the collision, in recent years, traffic regulations have increased the penalty of not fastening the safety belt in a bus, and some regions pay more attention to whether a passenger in the rear row of the operating vehicle fastens the safety belt or not, and the passenger is also penalized if the safety belt is not fastened.
In some related technologies, a seat weight detection device obtains a weight signal of a seated passenger, a seat belt length detection device detects a seat belt pull-out length displacement signal, a seat belt buckle detection device detects whether a seat belt buckle is buckled into a seat belt clamp seat, and finally, the seat belt pull-out length displacement range corresponds to different seat belts according to different weights so as to judge whether a passenger fastens the seat belt or not.
However, most of the existing vehicles only monitor and warn whether the front row driver and passenger seat belts are fastened well, the drivers are used to remind the rear row passenger to fasten the seat belts, many drivers do not really notice that the rear row passenger seat belts are not fastened, especially private drivers, it is unknown that the seat belts are equally important for the rear row passenger, even if the seat belt monitoring scheme disclosed above defines the length displacement ranges of different weights corresponding to different seat belt pulls, and then the seat weight detecting device, the seat belt length detecting device and the seat belt latch detecting device are used to detect the corresponding conditions in a matching manner to determine whether the passenger fastens the seat belts, certain errors still exist in the case of defining the passenger seat by weight, for example, the sizes of men and women with the same weight may have great differences, and the length displacement of the seat belt pulls may not be the same, if the judgment is carried out according to the same standard, the situation of misjudgment can occur, and for example, when an article with the weight similar to that of a human body is placed on a seat, the safety belt needs to be fastened according to the weight judgment, so that the situation is unreasonable. Therefore, further refinement is required for the monitoring of the seat belt.

Among them, the types of seat belts for vehicles are classified into a pretensioned type, a three-point type, a rear type, and a seat belt on a child seat, among which the three-point type is most widely used. When the same passenger uses different types of safety belts, the length of the drawn safety belts is different, therefore, the standard stretching length of different safety belt types corresponding to various character models needs to be predefined, therefore, an information base of the relation of the safety belt types-the character models-the standard stretching length can be prestored, in order to avoid different sizes of the passenger body types, a certain safety belt stretching length judgment error range is allowed to exist, the information base is stored in the
In the case of a seat belt of a child seat, since the child seat is installed on the rear-mounted seat, this special type requires the driver to set himself/herself which seat of the vehicle uses the child seat, and in the embodiment of the present invention, as shown in fig. 3, the seat

As shown in fig. 3, the safety
Particularly, for monitoring whether drivers and passengers fasten safety belts on vehicles, at present, most of the monitoring cameras on the roads are high-definition cameras by means of capturing pictures and carrying out technical analysis when the drivers and passengers patrol on the roads or pass through the snapshot cameras in the driving process of the vehicles, and whether the drivers and passengers fasten the safety belts or not can be quickly and accurately identified through a mature image identification algorithm, or monitoring equipment is additionally arranged on each vehicle, but the image identification technology is also used for judging whether the drivers and passengers fasten the safety belts or not. However, the current legislation only requires the see-through clarity of the front windshield, the front windshield of the vehicle cannot be pasted with a glass protective film with characteristics of dark color, light reflection and the like, but does not require other vehicle windows, and many vehicle owners can paste glass protective films with characteristics of dark color, light reflection and the like for improving the sun-shading effect, so that even though high-definition cameras can only capture images of front row drivers and passengers, certain blind areas exist for monitoring rear row passengers, the recognition rate is reduced, if traffic image monitoring equipment is additionally arranged on each vehicle, personal privacy is invisibly invaded to a certain extent, especially private vehicles, and therefore the feasibility of pushing is not high.
In view of the above problem, the embodiment of the present invention can more intuitively and clearly understand which position the seat belt is not fastened at present by projecting the seat belt monitoring information to a Display surface such as a windshield through the
