And the age information is obtained through the ECU of the DMS, the shape information and the global texture information of the human face are fully extracted, and the age is determined through an age identification algorithm. The age results were divided into three grades: under 40 years old, 40-60 years old, and over 60 years old. For example, 1 or less facial depression, 1 or less forehead wrinkles, 2 or less canthus lines, 1 or less cheek wrinkles, 0-2 spots of a peacock are judged to be under 40 years old; 2-4 facial depressions, 2-5 forehead wrinkles, 2-5 canthus crow wrinkles and 1-3 cheek wrinkles, and 3-6 spots of peacock are judged as age group 40-60 years old; for example, 5 or more facial depressions, 5 or more forehead wrinkles, 6 or more canthus lines, 4 or more cheek wrinkles, and 7 or more peacock are judged as over 60 years old.
Further, in the second step: the sign information includes a vision grade. And the step of acquiring the vision grade information comprises tracking the eyeball rotation frequency condition and the eyelid opening and closing condition in the specific time of the user through an infrared camera, and judging the vision grade of the user through an algorithm.
The DMS system obtains the behavior characteristics of a user watching the display of the multimedia system, and the level of poor eyesight is divided into three levels: weak, very weak. The eyeball keeps staring at the screen and does not move within 3S, and the opening distance of the eyelid is continuously reduced to 2/3 of the initial distance, so that the person with weak vision is judged; the eyeballs always stare at the screen within 5S and do not move, and meanwhile, the opening distance of the eyelids is continuously reduced to 1/2 of the initial distance, and the person with weak vision is judged; the eyeball keeps staring at the screen and does not move for more than 5S, the eyelid opening distance is continuously reduced to 1/3 of the initial distance, and even the repeated change of the eyelid opening size occurs for many times, thereby being judged as a person with very weak vision.
Step three: and determining an adjusting method for a display interface and/or display parameters of the vehicle-mounted display system according to a decision rule, wherein the decision rule comprises the corresponding relation between the sign information and the size of the display interface and/or the display parameters.
