Driving photographing system and method based on face recognition

Abstract

The driving photographing system comprises a central processing unit, an in-vehicle camera and an out-vehicle camera, the photographing direction of the out-vehicle camera can be rotatably adjusted, the in-vehicle camera is used for collecting face picture data of a driver, and the out-vehicle camera is used for collecting environment picture data around a vehicle. The central processing unit is used for recognizing the facial expression of the driver according to the facial picture data and judging whether the driver needs to rotate the outside camera or not, and is used for calculating the rotating angle of the face of the driver and controlling the outside camera to rotate. Whether the camera outside the automobile needs to rotate along with the head of the driver or not is determined through the facial expression, and the camera is kept consistent with the direction of the driver, compared with judgment through eye movement characteristics, the error-tolerant rate is higher, more accurate and more reliable, and therefore the problems that an existing automobile data recorder is large in view blind area and poor in use flexibility are solved; the effect of improving the reliability of the driving record video and the user experience is achieved.
