Description

Automatic adjustment control method and system for reading lamp and electronic equipment Technical Field The invention relates to the technical field of automobiles, in particular to a reading lamp automatic adjusting and controlling method, a reading lamp automatic adjusting and controlling system and electronic equipment. Background The reading lamp is usually fixedly arranged on the roof above the two rows of seats, and the irradiation angle is manually adjusted through a mechanical knob/deflector rod, so that the reading lamp does not have a front-rear position adjusting function. When the seat moves forwards and backwards, a proper angle can be found by repeatedly trying the knob/the deflector rod, and particularly, aiming at the scene of holding objects (such as books and computers) by old people, children passengers or both hands, the operation convenience is seriously insufficient, and when the position of part of the seat is still shielded by only adjusting the angle, taking a certain MPV as an example, the installation position of an aviation reading lamp corresponds to the initial adjustment position (the forefront position) of two rows of seats, and when the passenger adjusts the seat backwards to the position that the X direction (the front and rear directions of a vehicle) is overlapped with the installation position of the reading lamp, the angle of the reading lamp cannot be manually rotated to avoid the shielding. When the two rows of seats are adjusted to coincide with the mounting position X of the reading lamp, the head area of the passenger is directly positioned on the irradiation path of the reading lamp, and even if the angle of the reading lamp is adjusted to be the maximum (downward or forward), the head still can shield 30% -50% of light, so that the illuminance of the reading area above the knee (the core area under the main stream reading posture) is insufficient; In addition, the existing scheme can not identify the sitting posture difference of passengers (such as forward leaning reading and leaning sitting reading), the fixed angle adjustment can only cover a single sitting posture, and for passengers with different heights and sitting postures, the illumination coverage of 'no shielding and high accuracy' is difficult to realize. The key reason for the problems is that the existing reading lamp design does not form linkage adaptation with the seat adjusting function, and the problem that the seat X-position change and the passenger sitting posture difference cannot be dynamically matched only through a single mode of fixed installation position and manual angle adjustment, so that the adjustment flexibility and the illumination effectiveness are contradicted. Based on the above, the invention provides a reading lamp automatic adjustment control method, a reading lamp automatic adjustment control system and electronic equipment. Disclosure of Invention The invention aims to provide an automatic adjustment control method, an automatic adjustment control system and electronic equipment for a reading lamp, wherein manual operation is replaced by automatic identification and automatic adjustment, a user can complete position and angle adaptation without any manual intervention after opening the reading lamp, the problem of insufficient illumination caused by head shielding is thoroughly solved through front-back position adjustment (matching with the X-direction change of a seat) and automatic angle adaptation (avoiding a head area) of the reading lamp, the sitting posture (leaning forward/leaning sitting) and the space position of a passenger are identified through a camera, illumination parameters are dynamically adjusted, and the reading requirements of passengers with different heights and sitting postures are adapted. The invention provides the following scheme: In a first aspect, the present application describes a method for automatically adjusting and controlling a reading lamp, including the steps of: acquiring three-dimensional space matrix information of a passenger, wherein the three-dimensional space matrix information at least comprises seat X-position data and passenger space posture data; calculating the distance of the reading lamp to move back and forth according to the X-position data of the seat, outputting the information of the position of the reading lamp in front and back, calculating the irradiation angle according to the space posture data of the passenger, and outputting the information of the irradiation angle; The front-back position adjusting mechanism controls the reading lamp to move to the target position according to the front-back position information of the reading lamp, and the reading lamp adjusts the irradiation direction according to the irradiation angle information. Preferably, the seat X-position data is specific coordinates of the seat in the front-rear direction of the vehicle, which are determined by identifying seat slide graduations
