[0027] Please refer to Figure 1, is a flow chart of a vehicle-based adaptive image playback method provided in an embodiment of the present application. This embodiment is applied to a vehicle, wherein the vehicle includes a plurality of rotatable display screens, each of which is disposed at a different position in the vehicle. The method includes the following steps:

[0028] Step 101: Obtain the location information of each display screen.

[0029] In some embodiments, each display screen is matched with a driving hardware, and the setting parameters of the display screen are stored in the driving hardware; the position information of the display screen can be obtained by inputting the setting parameters into a preset AI model so that the AI ​​model outputs the position information.

[0030] It is worth noting that by inputting the setting parameters into the preset AI model to obtain the position information of the display screen, there is no need to manually calibrate the position of each display screen, which reduces the calibration workload and improves the degree of automation of the vehicle-based adaptive image playback method.

[0031] In some embodiments, the number and location of the display screens are not specifically limited and can be set according to actual needs. For example, the display screens can be multiple curved display screens arranged around the cockpit.

[0032] In some embodiments, the shape of the display screen is not specifically limited and can be set according to actual needs.

[0033] Step 102: Acquire head feature information of the person in the vehicle at every preset period, wherein the head feature information is used to characterize the visual angle of the person.

[0034] In some embodiments, the size of the preset period is not specifically limited and can be set according to actual needs. For example, the preset period can be 1 minute, 2 minutes, etc., or the value of the preset period can be set to 0, that is, the head feature information of the person in the vehicle is obtained in real time.

[0035] In some embodiments, the head feature information includes head movement features and eye movement features, which can be obtained through a head and eye tracking system.

[0036] It is understandable that this embodiment does not specifically limit the method for obtaining head feature information, and it can be set according to actual needs.

[0037] Step 103: selecting a target display screen from multiple display screens according to the most recently acquired head feature information at every preset period, wherein the position information of the target display screen matches the most recently acquired head feature information.

[0038] In some embodiments, the target display screen is selected according to the latest acquired head movement feature at every preset period. Specifically, according to the deviation angle of the person's head, the display screen facing the head is used as the target display screen.

[0039] Step 104: Control the target display screen to rotate to an angle that matches the head feature information, and control the rotated target display screen to play images.

[0040] In some embodiments, the target display screen is controlled to rotate to an angle that matches the eye movement characteristics, and then the rotated target display screen is controlled to play the image.

[0041] In some embodiments, through the rotation angle adaptation technology, the target display screen is adjusted to the most appropriate position for display according to the position of the person's head and eyes.

[0042] In some embodiments, before controlling the rotated target display screen to play the image, the image is also input into the AI ​​model so that the AI ​​model can understand the image content and automatically adjust the display focus to ensure that key information is always at the best viewing angle.

[0043] In some embodiments, based on the different rotation angles of the target display screen, the image displayed in the target display screen will also be adjusted according to the change in the rotation angle. For example, if the tilt angle of the target display screen is 45° and the displayed image is the sky, the displayed image will be adjusted to the image of the sky seen by the human eye when looking up at the sky at 45°, thereby creating an immersive feeling for the user and further improving the user's viewing experience.

[0044] In some embodiments, when there are multiple people in the vehicle, the vehicle will also obtain the position of each person and automatically adjust the surround center point position of the sound when playing the image according to the distribution position of the people, thereby further improving the user's viewing experience.

[0045] In some embodiments, the image includes sub-images of multiple focal lengths, and controlling the rotated target display screen to play the image includes: determining the visual focal length corresponding to the person's perspective based on eye movement characteristics; selecting a target focal length that is the same as the visual focal length from multiple focal lengths, and controlling the rotated target display screen to play the sub-image corresponding to the target focal length.

[0046] For ease of understanding, the following is a detailed description of how to control the target display screen to play images in this embodiment:

[0047] Assume that there are ten display screens, namely display screen 1 to display screen 10, which are respectively arranged at positions 1 to 10 in the vehicle. After acquiring the head feature information 1 of the person in the vehicle in the first preset cycle, the position in the vehicle that the person's head is facing is determined to be position 5 based on the head feature information 1, and the target display screen is determined to be display screen 5. Then, the rotation angle of display screen 5 is determined based on the eye movement characteristics of the person. After rotating display screen 5 according to the rotation angle, display screen 5 is controlled to play the image. During the image playback process, the current person's line of sight focus is determined according to the person's eye movement characteristics, so as to know which focal length of the image the person is currently watching. For example, the image includes sub-images of the three focal lengths of foreground, middle ground and background. If it is detected that the person's line of sight focus is in the middle ground, display screen 5 is controlled to play the sub-image of the middle ground.

[0048] Compared with the related art, the embodiment of the present application has at least the following advantages: by acquiring the head feature information of the person in the vehicle, since the head feature information is used to characterize the visual angle of the person, the target display screen is selected from multiple display screens according to the head feature information, which can ensure that the user has the best viewing angle; and since the display screen is rotatable, by controlling the target display screen to rotate to an angle that matches the head feature information, it is further ensured that the user is in the best viewing angle when the target display screen plays the image. In addition, since the head feature information is re-acquired at every preset period, the position and rotation angle of the target display screen will change with the change of the person's perspective, and high-quality, immersive image playback can be provided under different perspectives of the people in the car, thereby improving the user's experience.

[0049] Please refer to Figure 2 , which is a flow chart of the vehicle-based adaptive image playback method provided in an embodiment of the present application. This embodiment is a further improvement on the aforementioned embodiment. The main improvement is that: in this embodiment, before the image is played on the target display screen, the image will be blurred and rendered outside the viewing angle, thereby simulating the imaging effect when the human eye observes an object, further improving the user's visual experience.

[0050] This embodiment is applied to a vehicle and includes the following steps:

[0051] Step 201: Obtain the location information of each display screen.

[0052] Step 202: Acquire head feature information of the person in the vehicle at every preset period, wherein the head feature information is used to characterize the visual angle of the person.

[0053] Step 203: selecting a target display screen from multiple display screens according to the most recently acquired head feature information at every preset period, wherein the position information of the target display screen matches the most recently acquired head feature information.

[0054] Step 204: Control the target display screen to rotate to an angle that matches the head feature information.

[0055] Step 205: Determine the viewing angle range of the person according to the head feature information.

[0056] In some embodiments, the head feature information includes head movement features and eye movement features. The orientation of a person's head can be determined based on the head movement features, and the person's line of sight can be determined based on the eye movement features. Thus, the person's viewing angle range can be determined based on the orientation of the person's head and the person's line of sight.

[0057] Step 206: Perform blur rendering on the image outside the viewing angle range according to the viewing angle range.

[0058] In some embodiments, an image processing algorithm is used to render the image blurry outside the viewing angle.

[0059] Step 207: Control the rotated target display screen to play the blurred rendered image.

[0060] Steps 201 to 204 of this embodiment are substantially the same as steps 101 to 104 of the aforementioned embodiment, and are not described again here to avoid repetition.

[0061] Compared with the related art, the embodiment of the present application has at least the following advantages: by acquiring the head feature information of the person in the vehicle, since the head feature information is used to characterize the visual angle of the person, the target display screen is selected from multiple display screens according to the head feature information, which can ensure that the user has the best viewing angle; and since the display screen is rotatable, by controlling the target display screen to rotate to an angle that matches the head feature information, it is further ensured that the user is in the best viewing angle when the target display screen plays the image. In addition, since the head feature information is re-acquired at every preset period, the position and rotation angle of the target display screen will change with the change of the person's perspective, and high-quality, immersive image playback can be provided under different perspectives of the people in the car, thereby improving the user's experience.

[0062] Please refer to Figure 3 , which is a flow chart of a vehicle-based adaptive image playback method provided in an embodiment of the present application. This embodiment is a further improvement on the aforementioned embodiment. The main improvement is that: in this embodiment, the target display screen includes at least two adjacent display screens. Before playing the image, the image is also processed by video, so as to solve the compensation problem when the dynamic effect moves continuously between different display screens, ensure the smoothness of the picture, and further improve the user's visual experience.

[0063] This embodiment is applied to a vehicle and includes the following steps:

[0064] Step 301: Obtain the location information of each display screen.

[0065] Step 302: Acquire head feature information of the person in the vehicle at every preset period, wherein the head feature information is used to characterize the visual angle of the person.

[0066] Step 303: selecting a target display screen from multiple display screens according to the latest acquired head feature information at every preset period, wherein the position information of the target display screen matches the latest acquired head feature information.

[0067] Step 304: Control the target display screen to rotate to an angle that matches the head feature information.

[0068] Step 305: Perform video processing on the image so that the image is played on the target display screen with a continuous picture.

[0069] In some embodiments, the image is processed by a video processing algorithm. Specifically, since there may be gaps between adjacent display screens, when a moving object is displayed on multiple adjacent display screens, the display screen may be discontinuous. By performing video processing on the image, the compensation problem of the dynamic effect when it moves continuously between different display screens can be solved, the smoothness of the picture can be ensured, and the user's visual experience can be further improved.

[0070] Step 306: Control the rotated target display screen to play the image after the video processing.

[0071] In some embodiments, before controlling the target display screen after rotation to play the image after video processing, it also includes: adjusting the display parameters of the target display screen so that the display parameters of each display screen of the target display screen are the same; controlling the target display screen after rotation to play the image after video processing includes: controlling the target display screen after rotation and adjusting the display parameters to play the image after video processing.

[0072] Steps 301 to 304 of this embodiment are substantially the same as steps 101 to 104 of the aforementioned embodiment, and are not described again here to avoid repetition.

[0073] Compared with the related art, the embodiment of the present application has at least the following advantages: by acquiring the head feature information of the person in the vehicle, since the head feature information is used to characterize the visual angle of the person, the target display screen is selected from multiple display screens according to the head feature information, which can ensure that the user has the best viewing angle; and since the display screen is rotatable, by controlling the target display screen to rotate to an angle that matches the head feature information, it is further ensured that the user is in the best viewing angle when the target display screen plays the image. In addition, since the head feature information is re-acquired at every preset period, the position and rotation angle of the target display screen will change with the change of the person's perspective, and high-quality, immersive image playback can be provided under different perspectives of the people in the car, thereby improving the user's experience.
