Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of vehicles, and particularly relates to a display method and device, a vehicle, a storage medium and a program product. BACKGROUND

[0002] A HUD (Head-Up Display) is a display device that can project vehicle-related information in a transparent manner into the line of sight of a driver, so that the driver does not need to lower his head to check the instrument panel, thereby improving driving safety. The HUD display needs to be reflected on the windshield to display information. If the light outside the vehicle is too strong or too weak, it may interfere with the display effect of the HUD, and problems such as blurred text and color distortion are likely to occur, affecting the driver's accurate understanding of the displayed information. SUMMARY

[0003] To overcome the problems in the related art, the present disclosure provides a display method and device, a vehicle, a storage medium and a program product.

[0004] According to a first aspect of an embodiment of the present disclosure, a display method is provided, the method comprising:

[0005] In a case where the driving speed of the vehicle is less than a preset speed threshold and the steering angle is less than a preset angle threshold, a target image is obtained, the target image comprising a first sub-image and a second sub-image, the first sub-image comprising an image displayed on a display screen of the vehicle, and the second sub-image being determined according to images of an external environment of the vehicle collected within a preset time length;

[0006] The contrast of the target image is determined.

[0007] In a case where the contrast is less than a preset contrast threshold corresponding to a user account of the vehicle, a display parameter of the first sub-image is adjusted according to a color parameter of the second sub-image to increase the contrast of the target image, the display parameter comprising a display content parameter and / or a background parameter.

[0008] In this way, the display information on the display screen can be ensured to be clearly displayed in a case where the external environment of the vehicle interferes with the display information, thereby improving the user experience.

[0009] In some possible implementations, the adjusting of the display parameter of the first sub-image according to the color parameter of the second sub-image comprises:

[0010] In a case where the second sub-image is a single color, the display content parameter of the first sub-image is adjusted; or

[0011] In a case where the second sub-image comprises a plurality of colors, the display content parameter and / or the background parameter of the first sub-image is adjusted.

[0012] In this way, the first sub-image is adjusted in different adjustment manners according to the colors of the second sub-image, so that the contrast of the target image can be quickly and effectively increased.

[0013] In some possible implementation manners, the display content parameter comprises a color parameter of the display content; and the adjusting the display content parameter of the first sub-image comprises:

[0014] The display content in the first sub-image is subjected to color mixing processing to adjust the color parameter of the display content.

[0015] In this way, the contrast between the external environment and the display content on the display screen can be increased by subjecting the display content in the target region to color mixing processing, so that the display information on the display screen can be clearly displayed.

[0016] In some possible implementation manners, the display content parameter comprises a display position of the display content; and the adjusting the display content parameter of the first sub-image comprises:

[0017] The display position of the display content is adjusted according to the color parameter of the second sub-image and the color parameter of the display content in the first sub-image.

[0018] In this way, the display content can be adjusted to a position with a relatively large contrast with the environment by adjusting the display position of the display content, so that the display information on the display screen can be clearly displayed.

[0019] In some possible implementation manners, the display content parameter comprises a color parameter of the display content; and the adjusting the display content parameter and / or the background parameter of the first sub-image comprises:

[0020] The display content parameter is adjusted to increase the contrast of the target image to obtain a target contrast;

[0021] In a case where the target contrast is less than the preset contrast threshold, the background parameter of the first sub-image is adjusted.

[0022] In this way, the display content parameter is adjusted first and then the background parameter is adjusted, so that the contrast of the target image can be increased while the display content is adjusted in the smallest possible area.

[0023] In some possible implementation manners, the adjusting the display content parameter and / or the background parameter of the first sub-image comprises:

[0024] The background parameter of the first sub-image is adjusted.

[0025] In this way, the contrast of the target image can be increased quickly and effectively by adjusting the background parameter.

[0026] In some possible implementation manners, the background parameter comprises a background blur parameter; and the adjusting the background parameter of the first sub-image comprises:

[0027] The background blur parameter of the first sub-image is adjusted to perform a blur processing on the background of the target region.

[0028] In this way, by performing the blur processing on the background of the target region, the contrast between the external environment and the display content on the display screen can be increased, so that the display information on the display screen can be displayed clearly.

[0029] In some possible implementation manners, the background parameter comprises a background color parameter; and the adjusting the background parameter of the first sub-image comprises:

[0030] The background color parameter of the first sub-image is adjusted according to the color parameter of the second sub-image and the color parameter of the display content in the first sub-image.

[0031] In this way, by adjusting the color parameter of the background in the target region, the contrast between the external environment and the display content on the display screen can be increased, so that the display information on the display screen can be displayed clearly.

[0032] In some possible implementation manners, the adjusting the display parameter of the first sub-image according to the color parameter of the second sub-image in the case where the contrast is less than the preset contrast threshold corresponding to the user account of the vehicle comprises:

[0033] If the duration in which the contrast is less than the preset contrast threshold is greater than or equal to a preset time threshold, the display parameter of the first sub-image is adjusted according to the color parameter of the second sub-image.

[0034] In this way, the problem that the display content frequently changes due to frequent adjustment of the display parameter can be avoided.

[0035] In some possible implementation manners, the adjusting the display parameter of the first sub-image according to the color parameter of the second sub-image comprises:

[0036] The display parameter of the first sub-image is adjusted according to the color parameter of the second sub-image at a preset adjustment rate, so that the display parameter gradually changes.

[0037] In this way, by slowly adjusting the display parameter of the first sub-image, the display content on the display screen changes slowly, so that the adjustment of the display parameter is more natural, and the user cannot easily perceive it, thereby avoiding the problem that the adjustment of the display parameter is too abrupt and jarring.

[0038] In some possible implementation manners, the determining the contrast of the target image comprises:

[0039] dividing the target image into a plurality of regions to obtain a plurality of target sub-images;

[0040] determining the contrast of each of the target sub-images.

[0041] In this way, by dividing the target image into a plurality of target sub-images, the display of each sub-image can be adjusted according to the contrast of the sub-image, and the accuracy of image compensation is improved.

[0042] In some possible implementation manners, in a case where the contrast is less than a preset contrast threshold corresponding to a user account of the vehicle, the adjusting the display parameter of the first sub-image according to the color parameter of the second sub-image comprises:

[0043] for each of the target sub-images, in a case where the contrast is less than the preset contrast threshold, adjusting the display parameter of a target region in the first sub-image according to the color parameter of the second sub-image, the target region being a region corresponding to the target sub-image in the first sub-image.

[0044] In this way, in a case where the contrast is less than the preset contrast threshold, the display of the first sub-image on the display screen is adjusted to compensate for the first sub-image, and the display information on the display screen can be displayed clearly.

[0045] In some possible implementation manners, the obtaining the target image comprises:

[0050] obtaining the second sub-image by using an image acquisition device arranged outside the vehicle;

[0051] generating the target image according to the first sub-image and the second sub-image.

[0052] In this way, the target image in which the first sub-image and the second sub-image are overlapped can be generated according to the first sub-image displayed on the display screen and the second sub-image acquired by the image acquisition device arranged outside the vehicle without arranging the image acquisition device in the vehicle.

[0053] In some possible implementation manners, the acquiring the second sub-image by the image acquisition device arranged outside the vehicle includes:

[0055] determining a candidate image with a luminance in a preset luminance range from the environment image;

[0056] generating the second sub-image according to the candidate image.

[0062] In this way, different display content parameters can be used to display the first sub-image according to physiological features of different users, so as to meet individualized needs of different users.

[0063] In some possible implementation manners, the display content parameter includes a display position of display content, and the physiological feature information includes height information; and the determining the display content parameter of the first sub-image according to the physiological feature information includes:

[0064] determining the display position according to the height information and a first preset correspondence relationship, the first preset correspondence relationship including a correspondence relationship between the height and the display position.

[0065] In this way, the first sub-image can be displayed at different display positions according to height information of different users, so as to adapt to display position needs of different users and bring higher visual experience to the users.

[0066] In some possible implementation manners, the display content parameter comprises a contrast of the display content, and the physiological feature information comprises vision information; and the determining the display content parameter of the first sub-image according to the physiological feature information comprises:

[0067] determining the contrast according to the vision information and a second preset correspondence relationship, the second preset correspondence relationship comprising a correspondence relationship between the vision information and the contrast.

[0068] In this way, for different vision information of different users, the first sub-image can be displayed according to different contrasts, so as to adapt to the visual needs of different users and bring better visual experience to the users.

[0069] In some possible implementation manners, the method further comprises:

[0070] obtaining physiological feedback information of the user, the physiological feedback information comprising a blink frequency and / or a pupil size of the user;

[0071] updating the second preset correspondence relationship according to the physiological feedback information.

[0072] In this way, the correspondence relationship between the contrast and the vision information is adjusted in a timely manner according to the physiological feedback state of the user, so that the contrast of the display content is more adapted to the vision state of the user, and the visual experience of the user can be improved.

[0073] In some possible implementation manners, the method further comprises:

[0074] obtaining a target display parameter corresponding to a user account of the vehicle at present;

[0075] displaying the first sub-image on the display screen according to the target display parameter.

[0076] In this way, the first sub-image is displayed according to the corresponding display parameter for different user accounts, which can intelligently adapt to the driving habits of different users and improve the driving experience of the users.

[0077] In some possible implementation manners, the method further comprises:

[0078] obtaining an adjusted display parameter in response to the adjustment of the display parameter of the first sub-image;

[0079] updating the target display parameter according to the adjusted display parameter.

[0080] In this way, the target display parameter corresponding to the user account can be updated after the display parameter is adjusted each time by the user, so as to adapt to the actual driving habits of the user.

[0081] In some possible implementation manners, after the display parameter of the first sub-image is adjusted according to the color parameter of the second sub-image, the method further includes:

[0082] determining a contrast of the target image;

[0083] displaying the first sub-image on a screen of a vehicle in a case where the contrast is less than the preset contrast threshold.

[0084] In this way, by enforcing the display of the first sub-image on the screen of the vehicle, the clear display of the first sub-image can be ensured, and therefore the safety of driving is further improved.

[0085] In some possible implementation manners, in a case where the vehicle is in a preset scene, an adjustment range of the display parameter is less than a preset range threshold; the preset scene includes at least one of a sharp turning scene, an overtaking scene, an obstacle avoidance scene, a sharp braking scene, and a lane changing scene.

[0086] In this way, in a case where the vehicle is in a preset scene, the adjustment range of the display parameter is less than the preset range threshold, and therefore the variation of the display parameter in an extreme driving scene can be avoided from interfering with the driver.

[0126] The example embodiments will be described in detail herein with reference to the attached drawings. In the following description, unless otherwise indicated, like numbers in the attached drawings refer to the same or similar elements. The following detailed description of the embodiments does not represent all embodiments consistent with the present disclosure. Instead, they are merely examples in accordance with some aspects of the present disclosure as detailed in the appended claims.

[0127] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the corresponding data protection regulations and policies of the country where the device is located, and with the authorization of the owner of the corresponding device.

[0128] Before introducing the display method, device, vehicle, storage medium and program product according to the embodiments of the present disclosure, the application scenarios related to the embodiments of the present disclosure are introduced first.

[0129] The embodiments of the present disclosure can be applied to the HUD system, and can also be applied to other display screen systems inside the vehicle, etc.

[0130] Taking the HUD system as an example, the HUD system can project vehicle-related information in a transparent manner into the driver's line of sight, so that the driver does not need to lower his head to check the instrument panel, thereby improving driving safety. The functions of the HUD system can include: 1) driving navigation: project navigation information into the driver's line of sight, so that the driver can more conveniently understand information such as route, road conditions, etc.; 2) vehicle speed, speed, fuel quantity, etc. Information display: display the basic information of the vehicle in the driver's line of sight, so that the driver can more conveniently understand the vehicle state; 3) early warning: project safety warning information, lane departure warning, front vehicle collision warning, etc. Information directly into the driver's line of sight, so that the driver can react faster and take appropriate measures; 4) entertainment function: project music, video and other entertainment information in a transparent manner into the driver's line of sight, so that the driver can enjoy driving and entertainment at the same time. In summary, the HUD system improves driving safety and driving convenience.

[0131] Since the HUD display needs to be reflected on the windshield to display information, with reference to Figure 1 If the light outside the vehicle is too strong or too weak, it may interfere with the display effect of the HUD, and easy to appear fuzzy, color distortion and other problems, affecting the driver's accurate understanding of the display information, affecting the user's experience. The front camera sensor can be used to collect real-time graphics of the HUD display area in front of the human eye, and the domain control processor can be used to process the display content of the HUD according to the information collected by the camera, and compensate the display content of the HUD.

[0132] Figure 2 It is a schematic diagram of a HUD system and a car machine system according to an exemplary embodiment, with reference to Figure 2 The HUD system shown in the embodiment of the present disclosure can include: a HUD light device, an image collection device for the HUD display area, and a domain control processor. Wherein, the image collection device can be used to collect real-time graphics of the HUD display area in front of the human eye, and the domain control processor can be used to process the display content of the HUD according to the information collected by the image collection device, and compensate the display content of the HUD. And for different user accounts, the position of the HUD display area can be compensated and calibrated by the domain control processor, and the calibration information corresponding to the user account is stored in the memory.

[0133] The display method provided by the embodiments of the present disclosure can obtain a target image and determine the contrast of the target image when the driving speed of the vehicle is less than a preset vehicle speed threshold and the steering angle is less than a preset angle threshold. The target image includes a first sub-image and a second sub-image. The first sub-image includes an image displayed on the display screen of the vehicle, and the second sub-image is determined according to an image of the external environment of the vehicle collected within a preset time length. When the contrast is less than a preset contrast threshold corresponding to the user account of the vehicle, the display content parameter and / or the background parameter of the first sub-image are adjusted according to the color parameter of the second sub-image to increase the contrast of the target image. In this way, the display information on the display screen can be clearly displayed in the case that the external environment of the vehicle interferes with the display information, and the use experience of the user is improved.

[0134] Figure 3 FIG. 1 is a flowchart of a display method according to an example embodiment, as shown in FIG. 1, the method includes the following steps. Figure 3

[0135] In step S101, a target image is obtained when the driving speed of the vehicle is less than a preset vehicle speed threshold and the steering angle is less than a preset angle threshold. The target image includes a first sub-image and a second sub-image. The first sub-image can be an image displayed on the display screen of the vehicle, and the second sub-image is determined according to an image of the external environment of the vehicle collected within a preset time length. The target image can be a coincident image of the first sub-image and the second sub-image.

[0136] In examples, the display screen in the present disclosure can include a HUD, a transparent display screen projected on the windshield or the window, or a transparent display screen (such as a transparent center control screen) arranged in the vehicle, and the type of the display screen is not limited in the present disclosure.

[0137] In some embodiments, in order to avoid the change of the display parameter of the display screen in the extreme case of vehicle driving, the driving speed and the steering angle of the vehicle can be obtained first. If the driving speed is less than the preset vehicle speed threshold and the steering angle is less than the preset angle threshold, it indicates that the current driving state of the vehicle is relatively stable, and the display parameter of the display screen can be adjusted. If the driving speed is greater than or equal to the preset vehicle speed threshold, or the steering angle is greater than or equal to the preset angle threshold, it indicates that the current driving state of the vehicle is unstable, and the vehicle can be in a high-speed driving, sharp turning or other scene. In order to avoid affecting the safe driving of the user, the display parameter of the display screen can not be adjusted.

[0138] In other embodiments, the target image can include a background and display content. The display content can be, for example, navigation information, driving information, multimedia information, etc., and the background can be transparent, a specified color, a specified pattern or a specified texture, etc. ​

[0139] In some embodiments, the target image is obtained by an image acquisition device arranged inside the vehicle. For example, the image acquisition device can be a camera arranged at a designated position, such as a position close to the driver's eyes. The camera can directly obtain the image displayed on the display screen of the vehicle and the image of the environment outside the vehicle, i.e., the superimposed image of the first sub-image and the second sub-image, i.e., the target image.

[0140] In some embodiments, the first sub-image displayed on the display screen can be obtained, and the second sub-image can be obtained by an image acquisition device arranged outside the vehicle. Then, the target image can be generated according to the first sub-image and the second sub-image. For example, the first sub-image and the second sub-image can be superimposed to obtain the target image, which can represent the image obtained by superimposing the first sub-image displayed on the display screen and the environment outside the vehicle. The first sub-image and the second sub-image can be completely superimposed to obtain the target image. The first sub-image and the second sub-image can also be partially superimposed to obtain the target image. The present disclosure does not limit the superimposition manner of the first sub-image and the second sub-image.

[0141] In some embodiments, the environment image of the environment outside the vehicle within a preset time period can be obtained by the image acquisition device, thereby obtaining a plurality of environment images. The plurality of environment images obtained within the preset time period can include interfering light, such as a flashlight, tree shadow, strong or weak light at the entrance or exit of a tunnel, etc., which can cause overexposure or underexposure of the environment image. Therefore, a candidate image with a brightness within a preset brightness interval can be determined from the environment image to filter out the overexposed or underexposed environment image. Then, the second sub-image can be generated according to the candidate image. For example, a randomly selected image from the candidate image can be used as the second sub-image, or an image with a brightness closest to the preset brightness from the candidate image can be used as the second sub-image.

[0142] In step S102, the contrast of the target image is determined.

[0143] In some embodiments, the target image can be divided into a plurality of regions to obtain a plurality of target sub-images, and the contrast of each target sub-image can be determined to obtain the contrast of the plurality of regions. In some embodiments, the contrast of the target image can be periodically determined to obtain the contrast at a plurality of time points.

[0144] In step S103, in the case where the contrast is less than a preset contrast threshold corresponding to the user account of the vehicle, the display parameter of the first sub-image is adjusted according to the color parameter of the second sub-image to increase the contrast of the target image.

[0145] In some embodiments, the user can customize different preset contrast threshold values for different user accounts. If the contrast of the target image is less than the preset contrast threshold value, it indicates that the current contrast is too small, and the environmental background affects the clarity of the displayed content on the display screen, and therefore the display parameters of the first sub-image can be adjusted according to the color parameters of the second sub-image to increase the contrast of the target image. The display parameters can include display content parameters and / or background parameters. The display content parameters can be understood as the parameters of the specific content displayed on the display screen, such as the color parameters of the navigation information. The background parameters can be understood as the parameters of the background of the specific content displayed on the display screen, such as the color parameters and blurring parameters of the background area of the navigation information.

[0146] In other embodiments, in the case of a single color of the second sub-image, the display content parameters of the first sub-image can be adjusted. For example, in the case of a single green color of the second sub-image, the display content of the first sub-image can be adjusted to a color with a larger contrast with green. In the case of the second sub-image including multiple colors, the display content parameters and / or background parameters of the first sub-image can be adjusted.

[0147] For example, the display content parameters can include color parameters of the display content, and the display content in the target area can be subjected to color mixing processing to adjust the color parameters of the display content. The color parameters can include at least one of luminance, saturation, hue, color temperature, etc. For example, the hue can be adjusted by adjusting the H channel of the display content of the first sub-image in the HSV (Hue-Saturation-Value) space, the saturation can be adjusted by adjusting the S channel, and the luminance can be adjusted by adjusting the V channel.

[0148] For another example, the display content can be subjected to color mixing processing by additive color mixing or subtractive color mixing. Additive color mixing is to create other colors by mixing red, green and blue light, and multiple independent RGB (Red-Green-Blue) light sources can be used to achieve additive color mixing by focusing light beams of different colors to the same display area through an optical system. Subtractive color mixing is to create other colors by mixing yellow, magenta, cyan and black pigments, and filters can be used to achieve subtractive color mixing by sequentially absorbing light of specific wavelengths.

[0149] For another example, the display content parameter can comprise a display position of the display content, and the display position of the display content can be adjusted according to the color parameter of the second sub-image and the color parameter of the display content in the first sub-image. For example, the color parameter of the second sub-image indicates that the second sub-image comprises a blue region and a red region, and the color parameter of the display content indicates that the display content is blue. In this case, the display position of the display content can be adjusted to the red region to increase the contrast, so as to more clearly display the display content.

[0150] For another example, the display content parameter can comprise a color parameter of the display content. In the case where the second sub-image comprises a plurality of colors, the color parameter of the display content can be adjusted first to increase the contrast of the target image to obtain a target contrast. If the target contrast obtained after adjusting the display content parameter is less than a preset contrast threshold, the background parameter of the first sub-image can be adjusted to further increase the contrast of the target image.

[0151] For another example, in the case where the second sub-image comprises a plurality of colors, the background parameter of the first sub-image can be directly adjusted.

[0152] For another example, the background parameter can comprise a background blurring parameter. Adjusting the background parameter of the first sub-image can comprise adjusting the background blurring parameter of the first sub-image to perform blurring processing on the background of the target region. The background blurring parameter can be used to represent the blurring degree of the background. For example, the greater the value of the background blurring parameter, the higher the blurring degree of the background. The contrast can be negatively correlated with the background blurring parameter, that is, the greater the contrast, the lower the blurring degree of the background, and the smaller the contrast, the higher the blurring degree of the background.

[0153] For another example, the background parameter can comprise a background color parameter. Adjusting the background parameter of the first sub-image can comprise adjusting the background color parameter of the first sub-image according to the color parameter of the second sub-image and the color parameter of the display content in the first sub-image. For example, a color different from the color parameter of the second sub-image and the color parameter of the display content in the first sub-image can be selected as the background color of the first sub-image to increase the contrast of the target image.

[0154] For another example, the background parameter can comprise a background blurring parameter and a background color parameter. Adjusting the background parameter of the first sub-image can comprise adjusting the background blurring parameter of the first sub-image to perform blurring processing on the background of the target region, and adjusting the background color parameter of the first sub-image according to the color parameter of the second sub-image and the color parameter of the display content in the first sub-image.

[0155] In some embodiments, when the contrast is less than the preset contrast threshold, a duration of the contrast being less than the preset contrast threshold continuously can be recorded, and if the duration is greater than or equal to a preset time threshold, the display parameter of the first sub-image is adjusted according to the color parameter of the second sub-image, thereby avoiding the problem that the frequent changes of the display content or the background affect the user experience.

[0156] In some embodiments, the display parameter of the first sub-image can be adjusted according to the color parameter of the second sub-image at a preset adjustment rate, so that the display parameter gradually changes, thereby making the adjustment of the display parameter more natural and less noticeable to the user, and avoiding the problem that the change of the display parameter is too abrupt and jarring.

[0157] In some embodiments, the target image can be divided into multiple regions to obtain multiple target sub-images, and the contrast of each target sub-image can be determined. For each target sub-image, when the contrast is less than the preset contrast threshold, the display parameter of the target region in the first sub-image is adjusted according to the color parameter of the second sub-image, and the target region is the region corresponding to the target sub-image in the first sub-image. In this way, by dividing the target image into multiple target sub-images and adjusting the display parameter of each target region, the first sub-image can be adjusted more finely and accurately.

[0158] In some embodiments, after the display parameter of the first sub-image is adjusted according to the color parameter of the second sub-image, the contrast of the target image can be determined again, and if the contrast is still less than the preset contrast threshold, the first sub-image can be displayed on the vehicle infotainment screen. In this way, by forcing the display of the first sub-image on the infotainment screen, the clear display of the first sub-image can be ensured, thereby further improving the safety of driving.

[0159] In summary, the display method provided by the embodiments of the present disclosure can be used to obtain a target image and determine the contrast of the target image when the driving speed of a vehicle is less than a preset speed threshold and the steering angle is less than a preset angle threshold. The target image includes a first sub-image and a second sub-image, the first sub-image includes an image displayed on a display screen of the vehicle, and the second sub-image is determined according to an image of an external environment of the vehicle collected within a preset time duration. When the contrast is less than a preset contrast threshold corresponding to a user account of the vehicle, the display content parameter and / or the background parameter of the first sub-image are adjusted according to the color parameter of the second sub-image to increase the contrast of the target image. In this way, the display information on the display screen can be displayed clearly in the case that the external environment of the vehicle interferes with the display information, thereby improving the user experience.

[0160] Figure 4 is a flowchart of another display method according to an exemplary embodiment, as Figure 4As shown, the method can further include:

[0161] In step S104, physiological feature information corresponding to the current user account of the vehicle is acquired.

[0162] The physiological feature information can be used to represent the physiological state of the user, and the physiological feature information can include, for example, vision information, height information, eye position information, etc. The user can pre-enter the physiological feature information corresponding to the user account, and bind the user account with the physiological feature information.

[0163] In step S105, the display content parameter of the first sub-image is determined according to the physiological feature information.

[0164] In step S106, the first sub-image is displayed on the display screen according to the display content parameter.

[0165] In some embodiments, the display content parameter can include a display position of the display content, and the physiological feature information can include height information. Since the eye level of users of different heights is different, the display position can be determined according to the height information and a first preset correspondence relationship, and then the first sub-image is displayed on the display screen according to the display position, so that the display position of the display content is flexibly adapted to users of different heights. The first preset correspondence relationship can include a correspondence relationship between the height and the display position, and the height can be positively correlated with the display position, that is, the higher the height, the higher the display position on the display screen. The first preset correspondence relationship can be a correspondence relationship table or a correspondence relationship function between the height and the display position, and the specific form of the first preset correspondence relationship is not limited in the embodiments of the present disclosure.

[0166] In other embodiments, the display content parameter can include a contrast of the display content, and the physiological feature information can include vision information, which can include near vision, far vision, astigmatism, environmental light adaptation speed, amblyopia, etc. Since the vision information of different users is different, the contrast can be determined according to the vision information and a second preset correspondence relationship, and then the first sub-image is displayed on the display screen according to the contrast, so that the contrast of the display content is flexibly adapted to users in different vision conditions. The second preset correspondence relationship includes a correspondence relationship between the vision information and the contrast, and the second preset correspondence relationship can be a correspondence relationship table or a correspondence relationship model between the vision information and the contrast, and the specific form of the second preset correspondence relationship is not limited in the embodiments of the present disclosure.

[0167] In some embodiments, the physiological feedback information of the user can be obtained during the driving of the vehicle, wherein the physiological feedback information can include the blink frequency and / or the pupil size of the user. Since the physiological feedback information can represent the visual feedback of the user to the display content, for example, the high blink frequency indicates that the current display content is too high in visual stimulation for the user, and the large pupil diameter indicates that the display content is low in clarity, the second preset corresponding relationship can be updated according to the physiological feedback information, so that the corresponding relationship between the contrast and the vision information is adjusted in time according to the physiological feedback state of the user, so that the contrast of the display content is more adapted to the vision state of the user, and the visual experience of the user can be improved.

[0168] In some embodiments, the user can directly input the display parameters corresponding to different user accounts, and the target display parameters corresponding to the user account of the vehicle can be obtained after the vehicle is started, and the first sub-image can be displayed on the display screen according to the target display parameters, so as to intelligently adapt to the driving habits of different users and improve the driving experience of the user.

[0169] In some embodiments, the user can adjust the display parameters of the first sub-image during the driving of the vehicle according to the actual needs, and the adjusted display parameters can be obtained in response to the adjustment of the display parameters of the first sub-image, and the target display parameters corresponding to the user account can be updated according to the adjusted display parameters. In this way, the target display parameters corresponding to the user account can be updated after the user adjusts the display parameters each time, so as to adapt to the actual driving habits of the user.

[0170] In some embodiments, when the display parameters are adjusted in step S103, the adjustment range of the display parameters can be less than a preset range threshold in the case that the vehicle is in a preset scene, so as to avoid the interference of the change of the display parameters on the driver in the extreme driving scene. Wherein, each display parameter can be pre-set with a preset range threshold, and different display parameters can correspond to different preset range thresholds. For example, in the case that the display parameters include the display position and the display color saturation, the preset range threshold corresponding to the display position can be 1 cm, and the preset range threshold corresponding to the display color saturation can be 20%.

[0171] Wherein, the preset scene can include at least one of the sharp turning scene, the overtaking scene, the obstacle avoidance scene, the sharp braking scene and the lane changing scene, and each preset scene can be determined by pre-setting the corresponding conditions. For example, when the steering wheel angle is greater than 90 degrees, the steering rate is 60 degrees per second, and the lateral acceleration is greater than 0.4g, it can be determined that the vehicle is currently in the sharp turning scene. When the vehicle deviates from the original lane center line for more than two seconds, and the vehicle speed is greater than the speed of the front vehicle, it can be determined that the vehicle is currently in the overtaking scene.

[0172] Figure 5is a flowchart of another display method according to an example embodiment, as Figure 5 As shown in the method can further include:

[0173] In step S107, a display position parameter corresponding to the current user account of the vehicle is obtained. The display position parameter represents the display position of the display content on the display screen.

[0174] In step S108, the first sub-image is displayed on the display screen according to the display position parameter.

[0175] For example, if the second sub-image is obtained by the camera arranged outside the vehicle, and the target image is generated according to the first sub-image and the second sub-image, a problem will be faced that different users may see different overlapping parts of the display content on the display screen and the environment outside the vehicle due to the differences in individual height, sitting posture, etc. Therefore, different display position parameters need to be determined for different users so that the generated target image is consistent with the actual overlapping image seen by the user.

[0176] In some embodiments, for different users, the display position parameter can be calibrated by displaying a first test pattern and a second test pattern on the display screen. The first test pattern is a preset pattern, and the second test pattern is a pattern generated according to an environment image obtained by the image acquisition device of the vehicle. In response to an adjustment instruction, the display information of the display screen is adjusted to make the first test pattern and the second test pattern coincide.

[0177] For example, the first test image can be a circle or a square displayed at the center of the display screen, the camera can obtain an environment image outside the vehicle and generate a second test image according to the environment image, and then display the second test image on the display screen. Generally, the first test pattern and the second test pattern coincide by default, but due to the differences in height, front and back of the user, they may not coincide. If the first test pattern and the second test pattern do not coincide, the user can adjust the specified calibration key to control the first test pattern and the second test pattern to coincide. In the case where the first test pattern and the second test pattern coincide, a calibration success prompt information can be issued, and the calibrated display position parameter can be stored. In this way, the display position parameter of the display screen is calibrated for different users, avoiding the problem that the overlapping part of the display content on the display screen and the environment outside the vehicle seen by the user is different due to the differences in height, front and back of the user.

[0178] In other embodiments, the display position parameter can be bound to the current user account. In this way, each user can log in to the corresponding user account and obtain the display position parameter corresponding to the user account through the calibration operation.

[0179] In some embodiments, after the vehicle is powered on, the display position parameter corresponding to the current user account of the vehicle can be acquired, and the first sub-image can be displayed on the display screen according to the display position parameter. In this way, for different user accounts, the display position of the first sub-image is controlled according to the corresponding display position parameter, so that the target image generated according to the first sub-image and the second sub-image can be consistent with the actual image seen by the user, thereby more accurately compensating the first sub-image on the display screen for different users.

[0180] In summary, the display method provided by the embodiments of the present disclosure can acquire a target image and determine the contrast of the target image when the driving speed of the vehicle is less than a preset vehicle speed threshold and the steering angle is less than a preset angle threshold. The target image includes a first sub-image and a second sub-image. The first sub-image includes an image displayed on the display screen of the vehicle, and the second sub-image is determined according to an image of the external environment of the vehicle collected within a preset time length. When the contrast is less than a preset contrast threshold corresponding to the user account of the vehicle, the display content parameter and / or the background parameter of the first sub-image are adjusted according to the color parameter of the second sub-image to increase the contrast of the target image. In this way, the display information on the display screen can be clearly displayed in the case that the external environment of the vehicle interferes with the display information, thereby improving the user experience.
