The embedded processor 300 can be, for example, an android XU4, an android XU4 is an embedded processor manufactured by Hardkernel corporation of korea, and a core device of the embedded processor is a Samsung Exynos5422 eight-core processor, and the dominant frequency is as high as 2.1 GHz; the XU4 processor has two USB3.0 interfaces, one USB2.0 interface, and a standard network interface and an HDMI interface for display; the dimension is only 82 multiplied by 58 multiplied by 22, the unit is mm, and 5V power is supplied; the utility model discloses in, it is as the core processing device for the discernment and the task management of image.

The embedded processor of the utility model is supposed to be provided with a Linux operating system, Ubuntu 14.04; since the software work involves a lot of content, only the corresponding functional modules are listed here.

1) Task management, the system does not need to process high-speed images, but a safety belt wearing identification APP needs to remotely log in a plurality of vehicle-mounted cameras, process images from different cameras and need to carry out reasonable time sequence arrangement;

2) image recognition and processing, namely installing an OpenCV image processing software package based on an operating system, and performing work such as edge detection, feature matching and the like; designing a related recognition algorithm, and intelligently recognizing the seat state, whether a person sits or a safety belt is fastened or not;

3) the graphic display, in order to display the seat state, a GUI program (graphic display interface) needs to be compiled, and whether a person is in the seat or not and whether a safety belt is fastened or not are respectively displayed;

4) voice broadcasting, wherein a voice broadcasting function is required to be designed for voice prompt in cooperation with the wearing condition of the safety belt;

5) the information uploading is mainly data transmission based on network communication.

If the vehicle-mounted Wi-Fi exists, the network connection can be realized by inserting a USB wireless network card into the embedded processor; if the data uploading requires the use of a special network, an independent 4G internet module can be adopted and connected with the embedded processor through a network cable, and meanwhile, the hot spot function is closed, so that the external interference is reduced.

The embedded processor 300 is connected to the digital-to-analog module 400 through an HDMI interface, the digital-to-analog module 400 is connected to the audio device 501 and the driving recorder 502, on one hand, audio is output to the audio device 501 for sound alarm, on the other hand, video is output to the driving recorder 502, and a state image of a passenger wearing a seat belt is presented and stored; wherein,

the utility model discloses a rear-view mirror display screen (not shown) that is equipped with mainstream in the safety belt wearing identification system for vehicle seat, it supports two routes of video input, connects vehicle event data recorder all the way, and the image of backing a car is connected to another way, and the image of backing a car realizes priority through a control line and shows; under the normal state, the display screen of the rearview mirror is not connected with the automobile data recorder, and the display screen is not bright and is equivalent to the rearview mirror; by the level control of the control line, the driver operates the selection switch 503, and the switching between the seat state display and the mirror state can be realized.

It should be noted that: the video output interface of the embedded processor selected by the utility model is HDMI, which can not be directly connected with the rearview mirror display screen and needs the conversion of video images, so the digital-to-analog module 400 is adopted;

in addition, the mainstream rearview mirror display screen is generally provided with an android system, and development of safety belt wearing identification APP can be carried out; under the normal state, the display screen is not bright and is equivalent to a rearview mirror; under the power-on state, open APP, can realize the dynamic real-time demonstration of seat state.

The core of the seat belt wearing identification APP is an image processing algorithm, including identification of whether a person sits or not and whether a seat belt is worn or not when the person sits, and the algorithm can be simply described as follows:

people sitting and recognizing: mainly through judging the pixel change of the seat area, when no person sits, an empty seat image can be obtained in advance, when a person sits, the seat area can be obviously changed, and according to the characteristic, algorithm design is carried out to judge whether the person sits or not;

safety belt wearing identification: the method comprises the steps of sticking light-colored strips (obviously different from the color of the safety belt) to the area of the safety belt, selecting a seat area, carrying out contour recognition, and judging the direction slope of the contour in a plurality of contours, wherein the outlet and the inlet of the safety belt are fixed, and the trend of the safety belt is basically fixed, so that the method can effectively filter the interference of other contours; meanwhile, the pasted strip-shaped objects and the safety belts adopt contrast colors, so that the outlines are easy to find, the influence of wearing of passengers is not easy, and the recognition rate is high.

The HDMI interface of the embedded processor 300 includes video and audio outputs, and after passing through the digital-to-analog module 400, there are both video and audio outputs; the audio interface is connected with a proper conversion line, can be directly connected with the vehicle-mounted AUX port, and plays sound through the vehicle-mounted loudspeaker.

The seat image display and sound alarm functions can be realized through the processor and the sound module of the automobile data recorder.

If the image transmission adopts a wireless local area network mode, the image transmission can be realized by two modes:

1) the automobile data recorder serves as a hotspot, and the multiple cameras are connected to a hotspot network to form a local area network; the method has low cost and few used devices; the automobile data recorder can be inserted into a mobile phone SIM card of a mobile operator, and is accessed to the Internet to realize the cloud uploading of data in the future;

2) a vehicle-mounted wireless router is added, and the automobile data recorder and the camera are used as terminals to be accessed into a wireless network to form a local area network; the method increases equipment and cost, but is convenient for providing a stable network for passengers on the vehicle to connect with Wi-Fi to surf the internet.

Further, the seat belt wearing recognition system for a vehicle seat is further provided with a 5V power supply module for supplying power.

Therefore, the safety belt wearing and recognizing system for the vehicle seat of the utility model firstly judges whether a person sits on the seat through human shape matching; on the basis of sitting by a person, whether the passenger correctly wears the safety belt is judged by identifying the identification belt on the safety belt woven belt; for the person who is not wearing the seat belt, the voice prompt is performed, and the state image of the seat belt worn by the passenger is output and stored in the automobile data recorder.

In addition, the safety belt wearing identification system for the vehicle seat of the utility model can shoot the head portrait of the passenger and upload the shot head portrait of the passenger to the traffic management department; therefore, the passenger condition can be mastered in detail by the traffic management department, and better and safer social service is provided.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
