The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
With reference to the system architecture of the image display system, the following will describe an image display method in the present disclosure in detail, please refer to fig. 2, and fig. 2 is a schematic flow chart of the image display method provided by the present disclosure, where the image display method at least includes the following steps:
step 201: detecting a first position parameter of a focus of attention of a target user in a display plane; a still image is shown in the display plane.
The static image displayed in the display plane is obtained by uploading a video/picture to a cloud server for storage through an application program on the display device/control terminal by a user, and then preprocessing the video/picture by the cloud server, or directly processing the stored video/picture by the display device/control terminal.
Specifically, since the picture itself is static, it does not need to be correspondingly statically processed, but can be simply adjusted in contrast, brightness, color temperature, etc. according to the user's preference or the current environment, and static stickers are added on the basis of the original picture; for the video, because the video is composed of images of one frame and one frame, a proper frame can be extracted as a static cover to be displayed in the display plane according to the preference of the user, and meanwhile, the simple adjustment of contrast, brightness, color temperature and the like can be performed according to the preference of the user or the current environment, and a static sticker is added on the basis of the original image.
In one embodiment, each static image may be presented in the form of an electronic album. Specifically, a preset album display template acquired from the cloud server and each static image are fused to obtain a first display picture, and the first display picture is displayed on a display plane. The preset album display template is a template provided by the cloud server and used for displaying each display object (including pictures or videos), and the template may include a plurality of different display frames, and each display frame is used for displaying one display object. As shown in fig. 3, which is a schematic region view of an album display template according to an embodiment of the present disclosure, the album display template shown in fig. 3 includes 6 display frames, and the backgrounds (i.e., regions other than the display frames) of different album display templates are different, and in the album display template shown in fig. 3, the background is pure gray. The preset album display template can be a basic display template preset by a system or an album display template arranged by a user in a user-defined manner according to personal preferences. Whether the system is preset or the user-defined, the data can be uploaded to the cloud server to be stored, and then the data can be called from the cloud server through the display device when the data needs to be used. For example, each static image is filled into each display frame of the album display template shown in fig. 3, so as to obtain the first display picture shown in fig. 4, where the first display picture is composed of a display object a, a display object B, a display object C, a display object D, a display object E, a display object F, and the background of the album display template, each display frame correspondingly displays one display object, and the final first display picture is displayed in a display plane in a projection manner.
The display device can detect the current display environment through a built-in or external sensor (a camera, a TOF sensor, an infrared sensor, a UWB (ultra wideband) wireless distance measurement sensor, a millimeter wave sensor and the like), judge whether a user appears in the current display environment, and if no user is in the current display environment, all images in a current display plane are in a static state; when a user appears in the current display environment, the attention focus of the user is judged through the sensor, and then a first position parameter of the attention focus in the display plane is obtained. The method for judging the attention focus comprises angle/face orientation estimation of a user based on the body posture of the user, sight line estimation, pointing direction estimation of a finger of the user and the like.
In one embodiment, the specific step of estimating the attention focus of the user through the line of sight includes: acquiring the position information of both eyes and the head posture information of a target user; inputting the binocular position information and the head posture information into a sight evaluation model to obtain binocular sights of the target user; determining the attention focus of the target user according to the binocular vision and the display plane; determining a first position parameter of the attention focus point in the display plane according to a display plane coordinate system and the attention focus point. The binocular position information is a user binocular picture shot by the camera, and the head posture information is a user head picture shot by the camera; the binocular vision is a ray which is extracted from the eyes according to the vision direction.
Specifically, a picture of the eyes and the head of the user can be captured by a camera of the display device and then input into the sight line evaluation model for sight line estimation to obtain the binocular sight line of the target user. General gaze estimation can be divided into geometry-based methods, which are reading some features of the eyes (e.g., key points such as the corners of the eyes, the positions of the pupils, etc.) through photographs of the eyes, and appearance-based methods, which calculate binocular gaze in combination with the features of the eyes and the head pose, since the direction of gaze depends not only on the state of the eyes (eyeball position, degree of opening and closing of the eyes, etc.) but also on the head pose; the appearance-based method is to directly learn a model for mapping the appearances of eyes and heads to sight lines, and the sight lines of the eyes can be directly obtained through the model; the intersection point of the two eye sight lines falling on the display plane is the attention focus of the target user; finally, a first position parameter of the focus of attention in the coordinate system of the display plane may be determined based on the relative position of the focus of attention in the display plane, as will be described below.
Optionally, when the user has an obvious finger pointing direction, the attention focus can be estimated by the pointing direction of the user's finger, and the specific steps include: acquiring gesture information of a target user; recognizing the gesture information according to a gesture recognition model to obtain a first attention guiding line; determining a focus of attention of the target user based on the first attention guideline and the display plane; determining a first position parameter of the attention focus point in the display plane according to a display plane coordinate system and the attention focus point. The gesture information can be a picture of the hand of the user shot by the camera; the first attention guide line is a ray that starts from a finger having a directivity characteristic and is directed in the direction of the finger.
Specifically, a picture of the hand of the user can be taken through a camera of the display device, then the gesture information is input to the gesture recognition model, and the first attention guiding line is obtained through gesture detection, gesture segmentation, gesture analysis and static or dynamic gesture recognition. The most common gesture segmentation method at present mainly comprises gesture segmentation based on monocular vision and gesture segmentation based on stereoscopic vision; the gesture analysis is one of key technologies for completing a gesture recognition system, shape features or motion tracks of gestures can be obtained through the gesture analysis, and the gesture analysis is mainly carried out through an edge contour extraction method, a centroid finger and other multi-feature combination method, a finger joint type tracking method and the like; gesture recognition is a process of classifying tracks (or points) in a model parameter space into a subset of the space, and includes static gesture recognition and dynamic gesture recognition, and the dynamic gesture recognition can be finally converted into static gesture recognition, and the gesture recognition is generally performed by a template matching method, a neural network method and a hidden markov model method. Obtaining the finger pointing direction of a user through gesture recognition, wherein a ray taking the finger pointing direction as a direction with the finger of the user as a starting point is a first attention finger line, and the intersection point of the first attention finger line on a display plane is the attention focus of a target user; finally, a first position parameter of the focus of attention in the coordinate system of the display plane may be determined based on the relative position of the focus of attention in the display plane, as will be described below.
Alternatively, if a picture of the user's eyes cannot be taken and the user does not have a distinct finger pointing, the focus of attention can be estimated by the angle of the user's body posture or the orientation of the user's face, which includes the following specific steps: acquiring orientation information of a target user; determining a second attention guiding line according to an attention distinguishing model and the orientation information; determining an attention focus of the target user according to the second attention guideline and the display plane; determining a first position parameter of the attention focus point in the display plane according to a display plane coordinate system and the attention focus point. Wherein the orientation information of the user comprises the angle of the body posture of the user and the orientation of the face of the user.
Specifically, the body posture of the user or the face of the user can be shot through a camera of the display device, then the orientation of the body or the face of the user is obtained based on the shot image through posture angle recognition or face orientation recognition, the center of the body or the face of the user is regarded as a particle, a ray taking the particle as a starting point and the body orientation or the face orientation of the user as a direction is a second attention guideline, and the intersection point of the second attention guideline falling on the display plane is the attention focus of the target user; finally, a first position parameter of the focus of attention in the coordinate system of the display plane may be determined based on the relative position of the focus of attention in the display plane, as will be described below.
In one embodiment, in addition to the above manner of determining the user's focus of attention according to the sensor, the method may further include predicting a current first location parameter according to a location prediction model, so as to determine the user's focus of attention at a future time, and the specific steps include: predicting a third position parameter according to a position prediction model and the first position parameter; determining a future target static image according to the third position parameter and the second position parameter of each static image in the display plane; and dynamically preprocessing the future target static image to change the future target static image into a future dynamic image or video, and playing and displaying or caching the future dynamic image or video after the current dynamic image or video is played and displayed, so that the response speed can be improved, and the user experience is further improved. Wherein the third position parameter is a position parameter of the focus of attention at a future time in the display plane.
Because the attention focus is judged and obtained according to the sight line, the body posture/the face orientation or the finger pointing direction of the user, and the dynamic display content of the target display object obtained from the cloud is possibly limited by the reasons of the network speed and the like, the image display has some delay or slowness problems, if the attention focus can be pre-judged in advance, the static image in the attention focus range can be pre-processed in advance, and the delay or slowness problems can be relieved. Specifically, the position prediction model is trained according to a training set composed of a plurality of historical attention focuses, and the position prediction model can predict the attention focus at a future moment according to the attention focus at the current moment, namely predict where the user may look at the next moment. Assuming that the relevant content is scanned every second to acquire the focus of attention, that is, the acquisition period of the focus of attention is 1s, and assuming that the current time is 9: 00, the preset period is 10, then a total of 10 attention focuses can be obtained in the preset period, and the 10 attention focuses are respectively at the time 8: 51. 8: 52. 8: 53. 8: 54. 8: 55. 8: 56. 8: 57. 8: 58. 8: 59. 9: 00, the future time 9 can be predicted from these 10 focus of attention: 01, and finally, determining the location parameter of the attention focus point in the coordinate system of the display plane according to the predicted relative location of the attention focus point in the display plane, as will be described later.
After acquiring the attention focus of the user, the position of the attention focus in the display plane needs to be judged, in order to quantify the position of the attention focus in the display plane, the present disclosure proposes a concept of a position parameter, and the specific step of acquiring the position parameter thereof includes: modeling the display plane to obtain a display plane coordinate system; and determining a first position parameter of the attention focus in the display plane coordinate system according to the relative position of the attention focus in the display plane.
Specifically, as shown in fig. 5, a display plane coordinate system is established with any two sides of the display plane as coordinate axes, and then a position coordinate of the attention focus point, that is, a position parameter of the attention focus point in the display plane coordinate system, may be obtained according to a relative position of the attention focus point in the display plane coordinate system.
202: and determining the current target static image according to the first position parameter and the second position parameter of each static image in the display plane.
In an embodiment, after acquiring a first position parameter of an attention focus in a display plane and a second position parameter of each still image in the display plane, a still image in a user attention range or most relevant to the user attention range may be selected from the still images displayed in the current display plane as a current target still image according to a position relationship between the first position parameter and the second position parameter, and the specific steps include: determining a second position parameter of each static image on the display plane according to the relative position of each static image on the display plane; generating a user attention area according to the first position parameter; judging a second position parameter of each static image on the display plane and an associated parameter of the user attention area; and determining the current target static image from all the static images according to the associated parameters.
Taking the static images shown in the form of the electronic album as an example, since the electronic album is shown in the current display plane, the coordinate information of each static image in the album can be determined according to the display plane coordinate system, because the area occupied by each static image relative to the current display plane is relatively large, and each static image cannot be directly regarded as a particle, as shown in fig. 5, the coordinates of the four corners of each display frame and the coordinates of the center of the display frame can be used as the second position parameter of the display object. The display equipment draws a virtual circular area by taking the first position parameter of the current attention focus as the center of a circle and a preset attention radius R as the radius, wherein the area is the user attention area. After the user attention area is determined, calculating a second position parameter of each display object and an association parameter of the user attention area, namely a distance from four-corner coordinates and center coordinates of each display frame to the user attention area, wherein if the coordinates fall in the user attention area, the display object represented by the coordinates is a target static image, and otherwise, the display object is a non-target static image. As shown in fig. 5, the focus of attention of the user is the focus S in fig. 5, the radius of the user attention area is R, and the second position parameters of the display object a, the display object C, and the display object D fall into the user attention area, so that the display object a, the display object C, and the display object D are target still images, and the display object B, the display object E, and the display object F are non-target still images.
203: and dynamically processing the current target static image to change the current target static image into a current dynamic image or video, and playing and displaying the current dynamic image or video.
After the target static image which is in the user attention range or most relevant to the user attention range and the non-target static image outside the user attention range are screened out, the target static image is dynamically processed on the basis of the first display picture, so that the target static image is changed into a dynamic image or a video and is displayed in a playing mode, the non-target static image is still displayed in a static playing mode, a second display picture is obtained, and the second display picture is displayed in a display plane. As shown in fig. 5, in the current display plane, moving images or videos of the display object a, the display object C, and the display object D, and still images of the display object B, the display object E, and the display object F are displayed.
In one embodiment, the dynamic processing of the target still image may be by making a video by finding other images associated therewith, and includes the following specific steps: acquiring attribute information of a current target static image; determining a second image associated with the current target static image according to the attribute information; and generating a dynamic video based on the current target static image and the second image, and playing and displaying the dynamic video. Wherein the attribute information includes position information, person information, time information, and the like of capturing/acquiring the image; association means that at least one of the attribute information is the same or similar.
Specifically, the position information of the current target still image may be obtained, for example, the position information of the current target still image is in city a, so that at least one second image with the position information in city a may be downloaded from the cloud server according to the position information, and then the target still image and all the downloaded second images are made into a video for playing. For another example, the personal information of the current target still image is XX, the time is 5/6/2021 year, and the location is B city, so that at least one second image shot by XX in B city at 5/6/2021 year can be found locally or on the internet according to the cloud server, and then the target still image and all the downloaded second images are made into a video to be played.
In one embodiment, an image similar to the target still image can be found and made into a dynamic image, and the specific steps include: acquiring a third image similar to the current target static image; and generating a dynamic image based on the current target static image and the third image, and playing and displaying the dynamic image. Specifically, a third image similar to the target still image in terms of characteristics, which refer to image characteristics, is obtained, and then a dynamic image of the target still image is obtained through dynamic processing, where the dynamic processing may be to achieve an image dithering effect by jointly processing the target still image and the third image, and the like.
In an embodiment, a dynamic image may be obtained by dynamically transforming target feature points of a target static image, and the specific steps include: acquiring target characteristic points of a current target static image; and dynamically processing the current target static image based on the target characteristic point to generate a dynamic image, and playing and displaying the dynamic image. The target feature points, such as five sense organs (eyebrows, eyes, ears, nose, mouth) in the face, are processed to realize the moving effect of the face, so as to obtain a dynamic image corresponding to the target static image.
In the above process of dynamically processing the picture, a corresponding dynamic transformation parameter may be obtained according to the current environment or the preference of the user, so as to dynamically transform the picture based on the dynamic transformation parameter (for example, adding a dynamic special effect or dynamically rendering based on the dynamic rendering parameter), and finally obtain the picture with a dynamic effect, for example, identifying the content of the picture, and performing a targeted dynamic transformation on the picture (adding a fluttering effect to a static white cloud, adding a ripple scattering effect to a static water surface, and the like), for example, for the picture whose image content is difficult to identify, a layer of dynamic frame may be superimposed around the picture to form the picture with a dynamic effect, and in addition, a dynamic special effect and the like may be added on the picture to form the picture with a dynamic effect. The dynamic transformation parameters can include dynamic special effects (explosion, smoke, liquid, light effect, distortion, color change, blurring, shading, shaking, addition of variegated colors and the like), clockwise rotation of 90 degrees, right deviation of 10 pixels, up-down turning and the like; the dynamic transformation parameters may also be dynamic rendering parameters obtained by algorithms such as Nex (Real-time View Synthesis with Neural Basis Expansion, a novel View Synthesis method based on multi-plane image enhancement), LLFF (Local Light Field Fusion), NeRF (Neural network implicit Field method), and SRN (Spatial reconstruction, scene representation network).
The above contents are all examples of a target still image, i.e., a picture itself, and when the target still image is a certain frame image in a video, a video corresponding to the frame image can be directly pulled through the cloud server, and then the video is played and displayed in a current display plane or a certain section of the video is played and displayed. In addition, in order to increase the interest of video playing, dynamic special effects can be added to the video according to the current environment or the preference of a user (for example, some special effects/layers are inserted between frames to make the dynamic video look smoother, and for example, the brightness/color and the like of each frame of the video are processed to make the video look more uniform), so that a video picture with richer content is obtained.
