Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model discloses do not tie the warning to vehicle seat's safety belt among the correlation technique and have mistake and the higher problem of vehicle manufacturing cost, provide a safety belt reminding device and car.
As shown in fig. 1, the utility model provides a safety belt reminding device is applied to the vehicle, safety belt reminding device includes:
a camera disposed inside a vehicle;
an image processor connected to the camera;
a seat belt buckle detector for detecting a fastening state of the seat belt buckle, the seat belt buckle detector being disposed on the seat belt buckle;
a vehicle speed detector for detecting a vehicle running speed;
and the controller is respectively connected with the image processor, the safety belt lock catch detector and the vehicle speed detector.
In an embodiment of the present invention, the camera may be an infrared charge coupled CCD camera. The infrared CCD camera collects image information in the vehicle, and the collected image range comprises at least one monitored seat and is sent to the image processor. The working principle of the infrared CCD camera is based on an active infrared camera technology, namely when a photosensitive sensor in the camera detects that visible light is not enough to meet the requirement of image acquisition, a control module in the camera automatically turns on a semiconductor solid-state light-emitting infrared lamp to perform auxiliary illumination, the spectrum of the infrared lamp is within the range which can be sensed by a common CCD camera, and because human eyes are not sensitive to infrared light, the infrared camera can eliminate the influence of insufficient illumination on video acquisition during night driving and cannot interfere with normal driving of a driver.
In an embodiment of the present invention, the image processor may include:
the face detection unit is used for determining face region information according to the image information;
the seat detection unit is used for determining seat position information according to the image information;
and the matching unit is used for matching the face area information with the seat position information according to the image information and determining whether a passenger exists on the target seat according to a matching result.
In an embodiment of the present invention, the safety belt lock detector may be a sensor, and the safety belt lock detector sends a signal indicating whether the safety belt is fastened to the controller.
In an embodiment of the present invention, if the matching result indicates that there is a passenger in the target seat, the fastening state of the seat belt on the target seat is not fastened, and the vehicle speed is greater than or equal to a preset value, a seat belt fastening reminding signal is sent; otherwise, the safety belt buckle system reminding signal is not sent out.
