[0040] Figure 3 FIG. 4 is a diagram showing the internal structure of a computer device in one embodiment. DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] Light field screen technology is different from the display form of traditional car screens. The car-mounted light field screen is based on the principles of spatial optical technology. It increases the viewing distance by multiple reflections of light, achieves long-distance imaging effects, and carries a large-format display with a small physical screen.

[0043] At present, light field screens are mainly installed on the backrests of the front seats for rear passengers to watch. Under normal circumstances, the window range of the light field screen can cover the eyes of the rear passengers, thereby obtaining a good visual effect. However, the posture of the light field screen itself is affected by the front seats. For example, the angle of the backrest of the front seat will affect the direction of the light field screen. The posture of the rear passengers is uncertain. For example, the rear passengers may be lying on their backs, which will greatly reduce the imaging effect seen by the passengers.

[0044] The present application provides a light field screen imaging control method, which provides an automatic adjustment function of light field screen imaging parameters to match the current seat status.

[0045] The light field screen imaging control method of the present application is applied to a vehicle-mounted light field screen, wherein the vehicle cabin includes a first seat and a second seat arranged front and back, the first seat is in the front, and the second seat is in the back, the light field screen is arranged on the back of the first seat, such as the back of the seat or the back of the headrest, and the light field screen faces the second seat to provide image display for the occupant sitting on the second seat, and when the parameters of the first seat are adjusted, the light field screen also undergoes corresponding changes, for example, the pitch direction of the light field screen changes with the angle adjustment of the seat back, and the height of the light field screen changes with the height adjustment of the seat.

[0046] In one embodiment, the method is as follows Figure 1 As shown, the following steps are included:

[0047] Step 110, obtaining seat state parameters of the first seat and the second seat, including obtaining seat back angles corresponding to the respective seats.

[0048] In a car, the seat back can be adjusted manually or electrically. The seat back angle can be obtained based on a sensing unit such as an angle sensor provided in the seat adjustment structure, or in an electric adjustment mechanism, by recording the operating parameters of the drive motor (such as the number of revolutions of the motor), the operating parameters are mapped and converted into the seat back angle, and the sensing unit or the drive motor feeds back the signal to the MCU (Micro Control Unit).

[0049] It can be understood that, in this embodiment, the seat back angle may be the angle of the seat back relative to the vertical direction of the vehicle floor.

[0050] Since the light field screen is fixed relative to the first seat, the backrest angle of the first seat can reflect the posture of the light field screen itself, affecting the imaging direction of the light field screen and the window range of the eye receiving the image; and the passenger who receives the light field screen image sits on the second seat, and the backrest angle of the second seat can reflect the typical sitting posture of the passenger when sitting. For example, when the backrest angle of the second seat is high, it indicates that the passenger expects to maintain a supine posture and will adopt a supine posture more often. When the backrest angle of the second seat is small, it indicates that the passenger expects the upper body to remain upright and will adopt an upright posture more often. The passenger's posture affects whether the passenger's eyes fall into the window range of the light field screen.

[0051] Step 120: determining a target height of light field screen imaging according to the seat state parameter.

[0052] The backrest angle of the first seat and the backrest angle of the second seat are factors that affect imaging. For example, a mapping relationship between the combination of the backrest angle of the first seat and the backrest angle of the second seat and the imaging height is pre-established. For example, data calibration is performed by adjusting the imaging height so that under each combination of backrest angles, the window range of the light field screen after imaging can cover the headrest of the second seat and a certain range in front of the headrest, so that the person sitting on the second seat can obtain a good visual effect or the imaging distortion is within an acceptable range. The imaging height at this time is associated with the backrest angle combination to establish a mapping relationship between the backrest angle combination and the imaging height, and the mapping relationship is saved in the EEPROM (Electrically Erasable Programmable Read-Only Memory) of the light field screen. In the actual implementation process, the MCU calls the mapping relationship from the EEPROM through the current combination of backrest angles to find the target height.

[0053] Step 130: Control imaging of the light field screen according to the target height.

[0054] The imaging parameters of the light field screen, such as imaging height, imaging size, and imaging inclination, are controlled by the light field screen imaging system. After the MCU determines the target height, it sends the target height to the imaging system, and the imaging system adjusts the imaging height according to its own operating instructions.

[0055] The light field screen imaging control method provided in the above embodiment adjusts the imaging height based on the seat back angles of the first seat and the second seat arranged in front and behind, provides an automatic adjustment function of the light field screen in the cabin scene, and dynamically adapts to the adjustment of the front and rear seats in the cabin.

[0056] In another embodiment, the seat state parameters also include more parameters that affect the viewing effect. For example, the seat state parameters also include the relative distance between the first seat and the second seat in the horizontal direction. In the actual implementation process, a position sensing unit is set at the bottom of the first seat and the second seat to obtain the horizontal distance of the seat relative to its own origin and feed it back to the MCU. The MCU calculates the relative distance between the two seats according to the horizontal distance of the first seat relative to its own origin and the horizontal distance of the second seat relative to its own origin. If the origins of the two seats coincide, the relative distance in the horizontal direction is the difference between the horizontal distances of the two seats. If they do not coincide, the relative distance between the two seats needs to be calculated in combination with the horizontal distance between the two origins.

[0057] Then, based on the combination of relative distance and seat back angle, the target height after the light field screen imaging is determined. Similarly, the light field screen EEPROM pre-stores the mapping relationship between the relative distance, the seat back angle of the first seat, the seat back angle of the second seat and the imaging height. During the actual implementation process, the MCU obtains the target height from the mapping relationship.

[0058] In one implementation of the present embodiment, the seat state parameters also include the height difference between the first seat and the second seat. Similarly, the position sensing unit obtains the height of the seat relative to its own origin and feeds it back to the MCU. The MCU calculates the height difference between the two seats based on the height of the first seat relative to its own origin and the height of the second seat relative to its own origin, and determines the target height after imaging by the light field screen based on the combination of the height difference and the seat back angle. For example, the EEPROM pre-stores the mapping relationship between the height difference, the seat back angle of the first seat, the seat back angle of the second seat, and the imaging height. During the actual implementation, the MCU obtains the target height from the mapping relationship.

[0059] In another embodiment, the target height after imaging by the light field screen is determined based on the combination of the relative distance, height difference, and seat back angle. For example, the EEPROM pre-stores a mapping relationship between the relative distance, height difference, the seat back angle of the first seat, the seat back angle of the second seat, and the imaging height. During the actual implementation, the MCU obtains the target height from the mapping relationship.

[0060] The above embodiment adjusts the imaging height of the light field screen based on the seat state parameters. When the front seats or the rear seats are adjusted, the changed values ​​will trigger the automatic adjustment algorithm to automatically adjust the imaging of the light field screen again.

[0061] On the other hand, differences in the body shape of passengers, especially height, will also affect the passengers' viewing of the light field screen imaging. In another embodiment, based on image recognition, the eyes of the passengers are located, and the light field screen is adjusted based on the human eye coordinates. The exemplary process is as follows:

[0062] First, the eye height of the occupant sitting on the second seat is obtained, including obtaining an image of the occupant, wherein the image of the occupant at least includes the eyes of the occupant, and the image is obtained based on a camera in the cabin. For example, a cabin monitoring system is arranged in a smart vehicle to obtain images in the cabin from the front and process the image containing the occupant on the second seat; alternatively, a camera is set on the back of the first seat, which is dedicated to obtaining the image of the occupant on the second seat.

[0063] Then, based on the occupant image, the eye height of the occupant's eyes relative to a fixed reference point is determined, where the fixed reference point is, for example, a fixed point on a car body or a floor, and the fixed reference point is not affected by the adjustment of the seat; the input occupant image is preprocessed, such as grayscale, denoising, binarization, etc., so as to better extract the features of the eyes, and a face recognition algorithm is used to locate the eyes in the occupant image. Once the position of the eyes is determined, the height of the eyes in the image can be calculated by measuring the vertical image distance between the center of the eyes and the fixed reference point, and converted into a real distance based on the relationship between the image ratio and the real ratio.

[0064] It should be pointed out that if the camera is set on the back of the first seat, it will be affected by the state of the first seat and the image recognition result can be corrected by the seat state parameters of the first seat, such as height and backrest angle, so as to obtain a more accurate recognition result.

[0065] Finally, the target height after the light field screen imaging is determined according to the seat state parameters and the eye height.

[0066] In the actual implementation process, a mapping relationship between the seat state parameters, the combination of eye height and the imaging height is established in advance and stored in the EEPROM of the light field screen.

[0067] In particular, in the present application, the imaging height is adjusted according to the gear position, thereby simplifying the adjustment logic, reducing the requirements for real-time response of the system, and simplifying the system design and control algorithm. In addition, in the cabin scene, there is driving jitter, and the real-time adjustment of the light field screen will bring negative effects. Therefore, adjusting the imaging parameters according to the gear position is conducive to maintaining the stability of the picture presentation.

[0068] Exemplarily, the seat position is determined based on the range of the seat state parameter value. On the other hand, the eye height position is determined based on the range of the eye height value. Then, based on the seat position and the eye height position, the target height is determined by searching from a preset mapping relationship.

[0069] For example, seat gears are divided into angle gears, distance gears, and height gears according to their types. Each type is subdivided into multiple gears. The sensing unit obtains the seat back angle, horizontal distance, and height of the seat and sends them to the MCU. The MCU analyzes the angle gear (including the angle gear of the first seat and the angle gear of the second seat), distance gear, and height gear at this time based on the range of the seat back angle, the range of the relative distance, and the range of the height difference. On the other hand, the MCU also obtains the eye height gear based on the range of the eye height. Finally, the target height is found from the mapping relationship according to the angle gear, distance gear, height gear, and eye height gear of the seat.

[0070] It can be understood that the preset mapping relationship at this time is the corresponding relationship between each gear position and the imaging height.

[0071] The imaging effect of the light field screen is affected not only by the imaging height, but also by the imaging inclination, display size, etc. The following is an example of how to further improve the imaging effect:

[0072] In one embodiment, the left-right eye inclination of the occupant's eyes is determined based on the occupant image; and the imaging inclination of the light field screen is determined based on the range of the left-right eye inclination.

[0073] The left and right eye tilt angles need to be located using image processing technology. This can be achieved through various image recognition algorithms, such as template matching, feature point detection, etc. After the eye positions are determined, the eye tilt angles can be determined by calculating the coordinates of the two eyes.

[0074] Similar to the above-mentioned gear adjustment method, multiple tilt gears are pre-configured. Different tilt gears are for different tilt ranges. The current tilt gear is determined according to the range of the left and right eye tilts, so as to adjust the imaging of the light field screen to the imaging tilt corresponding to the current tilt gear.

[0075] In the back seat of the vehicle, passengers have a high degree of freedom and often lie on their backs or lean to the side. By monitoring the inclination of the left and right eyes and automatically adjusting the inclination angle of the image played on the light field screen, it can effectively prevent passengers from suffering eye fatigue due to changes in body posture that cause differences in the viewing angle and the imaging picture.

[0076] In yet another embodiment, the display size of the light field screen imaging is determined according to the seat state parameter; and the imaging instruction of the light field screen is executed according to the display size.

[0077] Exemplarily, the seat state parameters are as described above, including a combination of at least one or more of the seat back angles corresponding to the first seat and the second seat, the relative distance between the first seat and the second seat in the horizontal direction, and the height difference between the first seat and the second seat. The EEPROM pre-stores a mapping relationship between the seat state parameters or their combination and the display size. During the actual implementation process, the MCU searches the mapping relationship to obtain the final executed display size.

[0078] It should be understood that although Figure 1 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders.

The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.
