Description
Technical Field
The invention relates to the field of automobile face recognition, in particular to a method and a device for adjusting vehicle equipment parameters based on the automobile face recognition.
Background
At present, a face recognition technology is applied to a vehicle to improve driving experience, and parameters of vehicle equipment can be adjusted based on the face recognition technology, such as: different driver seat heights, etc. Because a driver does not always look ahead or a camera at every moment, the current algorithm cannot track the facial features of the driver all the time, whether the driver leaves or not cannot be judged, the face recognition starting condition cannot be used as a judgment condition by tracking the face, the face recognition result is wrong, and further equipment parameter adjustment errors are caused.
In the prior art, the opening and closing of a vehicle door is usually used as a face recognition function to be opened or closed, for example, ① opens the vehicle door to switch passengers by default, the face recognition function is always opened, ② closes the vehicle door, the current ID is kept unchanged after the face is recognized once, ③ the head characteristics of a driver leave a recognition area, and the ID is continuously sent when the face cannot be tracked.
Under some scenes, the scheme of further adjusting the parameters of the vehicle equipment based on the opening and closing of the vehicle door and the opening or closing of the face recognition function can bring poor driving experience. Such as:
(1) a driver has a rest on a driving position, and for the identified user, the driver opens the door to turn the head outwards, leaves the identification range, and just the head of the back-row passenger B faces forwards, enters the identification range of the camera, and is identified as B. At this time, the associated system is called according to the personalized setting of B, which brings trouble to the user and may even bring danger to the adjustment of the seat.
(2) No driver is on the driving seat, and the head of the passenger B in the back row just moves forward, enters the identification range of the camera and is identified as B. At this time, the associated system is called according to the personalized setting of B, which brings trouble to the user and may even bring danger to the adjustment of the seat.
(3) A driver opens the door of the vehicle at the driving position, and the human face recognition state is always kept at the moment. If A changes the face appearance gesture, it may be identified as other registered users or unregistered users. Although the probability of such problems is low, it still causes trouble to the user.
(4) The driver a changes the driver B wearing the mask for the identified user at the driving position, and at this time, the face recognition cannot judge that the driver has been changed. An error is displayed on the IPK.
(5) When the driver leaves the seat, the green head of a little person is still displayed on the IPK because the ID is continuously sent out, and the driver is identified.
Therefore, it is urgently needed to provide a technical scheme, which can solve the problem of vehicle equipment parameter adjustment errors caused by inaccurate face recognition results due to the existing limitations of the face recognition system.
