Problems solved by technology

The existing car audio-visual entertainment system monitors are all fixed between the main driver and the co-driver, and the position is high or low. This arrangement is simple, but it does not take into account the impact of different angles of sight and light on the use, and it does not take into account the impact of the co-driver. Ease of operation on the display

Embodiment 1

[0045] When the light outside the car is relatively strong and shines on the display device, the working process of a multi-degree-of-freedom car audio-visual entertainment automatic adjustment system based on light and line of sight is as follows: figure 2 shown, including the following steps:

[0046] S1: The photosensitive element 2 collects the information of the light irradiated on the display screen 3, and calculates the angle of the reflected light according to the light reflection theory to form Figure 4 light input;

[0047] S2: The camera 1 collects the eye position of the target person, and transmits it to the control unit to calculate the line of sight angle, forming Figure 4 line of sight input;

[0048] S3: Calculate the theoretical optimal position of the display screen 3 through the function fcn, judge whether the display screen 3 is in the optimal position, output 0 to indicate that the current position is within the optimal range, and no movement is allo...

Embodiment 2

[0051] When the driver and passengers feel that the operation is inconvenient and need to move away from or draw closer to the display device, a multi-degree-of-freedom car audio-visual entertainment automatic adjustment system based on light and line of sight works as follows: image 3 shown, including the following steps:

[0052] S1: The co-pilot gives a voice command to command the display device to move to the side of the co-pilot to form a Figure 4 voice input;

[0053] S2: Calculate the moving distance through the function fcn(u, v), and send it to the moving motor 11 after passing through the control module. If the moving distance reaches the command requirement or the passenger on the co-pilot side receives a stop instruction, stop moving and go to step 3, otherwise continue to move until the rightmost side and go to step 3;

[0054] S3: The camera 1 collects the line of sight angle of the co-pilot observing the display screen 3 as Figure 4 line of sight input, p...

Abstract

The invention provides a method and a device for adjusting a multi-degree-of-freedom vehicle-mounted audio-video system based on light rays and sight lines. Aiming at the influence of light on observation of a display of an audio-video system by a driver and inconvenience of man-machine interaction, automatic adjustment including up-and-down rotation, left-and-right rotation and left-and-right movement is carried out on the display by detecting the angle relation between the light and the sight line; therefore, the man-machine interaction convenience of an existing product, especially a co-driver position and a display screen is improved. According to the invention, the influence of light on the sight line of a driver is solved, unclear object vision caused by the light is prevented, and clearer interface content is provided for the driver. The method and device is simple in structure and low in cost.

Description

technical field [0001] The invention belongs to the field of vehicle audio-visual technology, and in particular relates to a method and device for adjusting a multi-degree-of-freedom vehicle audio-visual system based on light and line of sight. Background technique [0002] With the introduction of the smart cockpit concept, the car audio-visual entertainment system is no longer limited to simple functions such as radios. Its functions are more abundant, and human-computer interaction is more frequent, which puts forward higher requirements for car audio-visual systems and equipment. The existing car audio-visual entertainment system monitors are all fixed between the main driver and the co-driver, and the position is high or low. This arrangement is simple, but it does not take into account the impact of different angles of sight and light on the use, and it does not take into account the impact of the co-driver. Ease of operation on the display. Contents of the invention...
