[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0049] The embodiments of the present application provide a method, device, computer device and storage medium for intelligent rotation of a multimedia playback device. Specifically, the embodiments of the present application provide an intelligent rotation device for a multimedia playback device suitable for a computer device. The computer device may be a terminal or a server or other device, and the server may be an independent physical server, or a server cluster or distributed system composed of multiple physical servers. The terminal may be a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart speaker, a smart watch, etc., but is not limited thereto. The terminal and the server may be directly or indirectly connected via wired or wireless communication, which is not limited in the present application.

[0050] refer to Figure 1 Taking a computer device as a server as an example, the server can determine the first eye position information of the target user corresponding to the current multimedia playback device; when it is detected that the target user moves, the second eye position information of the target user after the movement is determined; based on the first eye position information and the second eye position information, the multimedia playback device is rotated.

[0051] From the above, it can be seen that the embodiments of the present application can rotate the multimedia playback device accordingly by determining the viewing position information of the user after movement, that is, the eye position information of the user after movement. For example, the rotation angle of the multimedia playback device that needs to be rotated accordingly can be determined based on the eye position information after movement, and then the multimedia playback device can be flexibly rotated according to the rotation angle, so that the user can have a better viewing angle and the user's viewing experience can be improved.

[0052] The present embodiments may be described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0053] The embodiment of the present application provides a method for intelligently rotating a multimedia player, which can be executed by a terminal or a server, or by both the terminal and the server. The embodiment of the present application takes the method for intelligently rotating a multimedia player as an example, and specifically, the method is executed by an intelligent rotating device of the multimedia player integrated in the server. Figure 2a As shown, the specific process of the intelligent rotation method of the multimedia playback device can be as follows:

[0054] 201. Determine first eye position information of a target user corresponding to a current multimedia playback device.

[0055] The multimedia playback device is a playback device that plays various videos, images, audios and other contents. For example, the multimedia playback device can be a television, a computer, a projector and other devices.

[0056] Among them, the first eye position information includes information about the position of the target user's eyes. For example, a camera can be installed on the top of the display of the multimedia playback device. The target user opposite the current multimedia playback device is photographed by the camera to obtain a first image, and then face recognition is performed on the image to determine the position of the target user's eyes, thereby obtaining the first eye position information of the target user.

[0057] In one embodiment, in order to determine the eye position information of the target user, face recognition may be performed on an image containing the target user. Specifically, the step of “determining the first eye position information of the target user corresponding to the current multimedia playback device” includes:

[0058] Acquire a first image of a preset area opposite to the current multimedia playback device;

[0059] Identify the face information of the target user in the first image and determine the first eye position information of the target user.

[0060] The preset area may be an area opposite to the current multimedia playback device, for example, an area captured by a camera in the multimedia playback device, and the area may include a user image of a user watching a video.

[0061] In one example, a television is used as an example of a multimedia playback device. Nowadays, televisions are placed at fixed angles, but the sofas in the living room are placed in a wide position. When viewers watch TV at different angles, the TV picture cannot face the viewer, resulting in a poor viewing experience. At this time, a camera can be installed on the top of the TV monitor, and a controllable horizontally rotating platform is added to the base of the TV. An image processor is added to connect the camera and the rotating platform. The image processor processes the collected real-time images, performs face detection, analyzes the location information of the viewer (e.g., target user), and then calculates the rotation angle of the platform and controls the rotation of the platform to put the viewer at the best viewing angle.

[0062] Among them, when a small movement of the viewer is detected, for example, the movement distance is within the preset allowable movement range, it is not necessary to calculate the rotation angle of the platform and control the rotation of the platform. When a large movement of the viewer is detected, for example, the movement distance is not within the preset allowable movement range, the rotation angle of the platform must be calculated and the rotation of the platform must be controlled.

[0063] In another example, taking the multimedia playback device as a television as an example, the first image of the preset area opposite to the current multimedia playback device can be obtained as follows: Figure 2b As shown, the rectangle in the figure represents the range of the image captured by the camera device in the multimedia playback device, the target user in the middle represents the user within the field of view of the camera device, the distance a and the distance b represent the distance from the target user to the edge, the first image includes the target user, and face recognition is performed on the first image, and the first eye position information of the target user can be determined based on the recognition result.

[0064] Among them, face recognition is performed on the first image to identify the face in the first image, and then the eye area of ​​the face is initially located, noise is removed, and the eyes are accurately located, so as to obtain the first eye position information of the target user in the first image.

[0065] 202. When it is detected that the target user moves, determine second eye position information after the target user moves.

[0066] Among them, the second eye position information includes information about the position of the target user's eyes after the target user moves. For example, a camera can be installed on the top of the display of the multimedia playback device, and a second image of the target user after the target user moves is captured by the camera. Then, face recognition is performed on the second image to determine the position of the target user's eyes after the target user moves, thereby obtaining the second eye position information of the target user.

[0067] The target user can move in any direction, for example Figure 2cAs shown, the target user can move toward the direction of C1, can move toward the direction of C2, can also move toward the direction between C1 and C2, and so on.

[0068] In one embodiment, in order to avoid frequent rotation of the multimedia playback device caused by face shaking error, when the distance moved by the target user is within the allowable error range, the multimedia playback device may not be rotated. Specifically, the intelligent rotation method of the multimedia playback device may further include:

[0069] Determine the ratio of the distance between the position of the target user after the user moves and the two sides of the first image, the position after the user moves being the position corresponding to the second eye position information;

[0070] When the distance ratio is within a preset distance ratio range, the playback angle of the multimedia playback device is kept unchanged, and the multimedia playback device is not rotated.

[0071] Among them, the distance ratio is the ratio of the distance to one side of the first image and the distance to the other side of the first image after the target user moves. When the distance ratio is within the preset distance ratio range, it means that the distance moved by the target user is within the allowable error range, so the multimedia playback device will not rotate at this time, and frequent movement of the multimedia playback device caused by the error of slight movement of the target user can be avoided.

[0072] In one example, a multimedia playback device is taken as a television set for example. Figure 2d As shown, the target user has moved from the position before the movement to the later position as shown in the figure. If, after the target user moves to the later position, the ratio of the distance of the target user to the left side of the first image to the distance to the right side of the first image, that is, the ratio of distance a to distance b, is within a preset distance ratio range (for example, the preset distance ratio range can be 0.9 to 1.1, that is, the ratio of distance a to distance b is between 0.9 and 1.1), then the playback angle of the multimedia playback device can be kept unchanged, and the multimedia playback device will not be rotated.

[0073] Among them, if after the target user moves to the moved position, the ratio of the distance from the target user to the left side of the first image to the distance to the right side of the first image, that is, the ratio between distance a and distance b, is not within the preset distance ratio range, the rotation angle of the multimedia playback device can be adjusted so that the distance between the two sides of the image reached by the target user after the moved position captured by the camera device in the multimedia playback device is within the preset distance ratio range.

[0074] 203. Rotate the multimedia playback device based on the first eye position information and the second eye position information.

[0075] Rotation refers to rotating the multimedia playback device according to the position of the target user's eyes, so that the target user has a good angle to watch the content played by the multimedia playback device, which can improve the user's viewing experience.

[0076] In one embodiment, in order to optimize the viewing angle of the content played by the multimedia playback device for the user, the multimedia playback device may be rotated accordingly by determining the position information of the user. The step of “rotating the multimedia playback device based on the first eye position information and the second eye position information” may include:

[0077] Determining a rotation angle of the multimedia playback device based on the first eye position information and the second eye position information;

[0078] Rotate the multimedia player according to the desired rotation angle.

[0079] In one example, the longitude and latitude information of the target user before moving and the longitude and latitude information of the target user after moving can also be determined based on the first eye position information and the second eye position information. The rotation angle of the multimedia playback device to be rotated is calculated based on these two longitude and latitude information and the current longitude and latitude information of the multimedia playback device. Finally, the multimedia playback device is rotated according to the calculated rotation angle, so that the target user can have a good visual angle to watch the content played by the multimedia playback device.

[0080] In one embodiment, in order to optimize the viewing angle of the content played by the multimedia playback device for the user, the multimedia playback device may be rotated accordingly by determining the position information of the user. Specifically, the detailed process of the step of "determining the angle to be rotated of the multimedia playback device based on the first eye position information and the second eye position information" may include:

[0081] Determine a moving distance of the target user based on the first eye position information and the second face position information;

[0082] Obtaining the viewing distance from the multimedia playback device to the target user before the target user moves;

[0083] Based on the moving distance and the viewing distance, the angle to be rotated of the multimedia playback device is calculated.

[0084] In one example, the moving distance of the target user and the distance from the multimedia playback device to the target user before the user moves are determined. There are multiple algorithms to calculate the rotation angle of the multimedia playback device. Here is one example to illustrate. For example, knowing the two distances, the relevant trigonometric functions can be used to calculate the angle value of the rotation angle.

[0085] In one embodiment, in order to improve the viewing experience of users, when there are multiple users watching the content played by the multimedia playback device, the location information of the users at two end points can be determined. When the positions of the users at the two end points move, the multimedia playback device is rotated accordingly. Specifically, the intelligent rotation method of the multimedia playback device can also include:

[0086] When it is detected that a corresponding viewing area of ​​the multimedia playback device includes a plurality of viewing users, acquiring a second image of the viewing area;

[0087] Recognize facial information of multiple movie-watching users in the second image, and determine viewing eye position information of two target movie-watching users at two ends of the second image;

[0088] When it is detected that the viewer's eye position information has changed, the rotation angle of the multimedia playback device is adjusted so that the ratio of the distances between the two target viewers and the two sides of the third image is within a preset distance ratio range, and the third image is an image of the viewing area after the viewer's eye position has changed.

[0089] The viewing area refers to the area opposite to the multimedia playback device, and the range that can be captured by the camera device in the multimedia playback device is the range where the area is located.

[0090] In one example, when there are multiple viewers watching content played by a multimedia player, a second image containing multiple viewers can be obtained, face information in the second image can be identified, and the viewer eye position information of each viewer can be determined. When at least one viewer is detected to move, the viewer eye position information of each viewer after the movement is obtained, such as Figure 2e As shown, Figure 2e The positions of the viewers are the positions after the viewers move, and the distances from the eyes of the viewers at both ends of the viewers to the two sides of the image are determined, that is, Figure 2e The distance c and the distance d in the figure are used to determine whether to adjust the rotation angle of the multimedia playback device according to the ratio between the distance c and the distance d.

[0091] Among them, when the ratio between the distance c and the distance d is within the preset distance ratio range, the playback angle of the multimedia playback device is kept unchanged and the multimedia playback device is not rotated. When the ratio between the distance c and the distance d is not within the preset distance ratio range, the rotation angle of the multimedia playback device is adjusted so that the ratio of the distances between the two sides of the image captured by the camera device from the viewing users at both ends is within the preset distance ratio range.

[0092] In one embodiment, for the user's viewing experience, the user's viewing preference may be determined by analyzing the content watched by the user, and then content recommendation may be performed. Specifically, the intelligent rotation method of the multimedia playback device may also include:

[0093] Obtaining video contents of multiple target videos watched by a target user and the viewing time of each target video, where the target video is a video played by a multimedia playback device;

[0094] Based on video content and viewing time, content recommendations are made to target users through multimedia video playback devices.

[0095] In one example, taking a television as an example of a multimedia playback device, the program content of the TV programs watched by the target user, the viewing time of different TV programs, and the frequency of changing channels can be obtained to determine the viewing preferences of the target user, and then recommend TV programs, items, and other content that may be preferred to the target user.

[0096] In one embodiment, in order to more intelligently control the multimedia playback device, the control authority of the multimedia playback device may be set. Specifically, the intelligent rotation method of the multimedia playback device may further include:

[0097] When multiple users have control authority over the multimedia playback device, receiving a control instruction from the current user;

[0098] Collect the user information of the current user, including the user's face information and the user's voice information;

[0099] When the user face information and the user voice information match the preset face information and the preset voice in the user authority database, the multimedia playback device is controlled based on the control instruction.

[0100] In one example, users who have control authority over the multimedia playback device can be set in advance, and facial image information and voice information of these users can be collected and stored in a user authority database. Only users with control authority can control the multimedia playback device. For example, these users with control authority can switch the content played by the multimedia playback device through voice commands (for example, if the content is "play current news", the content currently played by the multimedia playback device can be switched to current news), and can rotate the angle of the multimedia playback device through voice commands, etc.

[0101] From the above, it can be seen that the embodiments of the present application can rotate the multimedia playback device accordingly by determining the viewing position information of the user after movement, that is, the eye position information of the user after movement. For example, the rotation angle of the multimedia playback device that needs to be rotated accordingly can be determined based on the eye position information after movement, and then the multimedia playback device can be flexibly rotated according to the rotation angle, so that the user can have a better viewing angle and the user's viewing experience can be improved.

[0102] In order to better implement the above method, accordingly, the embodiment of the present application also provides an intelligent rotation device for a multimedia playback device, wherein the intelligent rotation device for the multimedia playback device can be specifically integrated in a server, referring to Figure 3a , the intelligent rotation device of the multimedia playback device may include a first information determination unit 301, a second information determination unit 302 and a rotation unit 303, as follows:

[0110] (3) Rotation unit 303;

[0111] The rotation unit 303 is used to rotate the multimedia playback device based on the first eye position information and the second eye position information.

[0116] In one embodiment, the intelligent rotating device of the multimedia playback device further includes:

[0117] A position determination unit 304 is used to determine the ratio of the distance between the target user's position after the target user moves and the two sides of the first image, wherein the position after the target user moves is the position corresponding to the second eye position information;

[0118] The angle maintaining unit 305 is used to maintain the playing angle of the multimedia playing device unchanged and not to rotate the multimedia playing device when the distance ratio is within a preset distance ratio range.

[0119] In one embodiment, the intelligent rotating device of the multimedia playback device further includes:

[0120] A first acquisition unit 306 is configured to acquire a second image of the viewing area when it is detected that the viewing area corresponding to the multimedia playback device includes a plurality of viewing users;

[0121] The information recognition unit 307 is used to recognize the facial information of multiple movie-watching users in the second image, and determine the viewing eye position information of two target movie-watching users at two ends of the second image;

[0122] The adjustment unit 308 is used to adjust the rotation angle of the multimedia playback device when it is detected that the viewer's eye position information has changed, so that the ratio of the distances between the two target viewers and the two sides of the third image is within a preset distance ratio range, and the third image is an image of the viewing area after the viewer's eye position has changed.

[0123] In one embodiment, the intelligent rotating device of the multimedia playback device further includes:

[0124] A second acquisition unit 309 is used to acquire video contents of multiple target videos watched by a target user and a viewing time of each target video, where the target video is a video played by a multimedia playback device;

[0125] The content recommendation unit 310 is used to recommend content to target users through a multimedia video playback device based on video content and viewing time.

[0126] In one embodiment, the intelligent rotating device of the multimedia playback device further includes:

[0129] The control unit 313 is used to control the multimedia playback device based on the control instruction when the user face information and the user voice information match the preset face information and the preset voice in the user authority database.

[0130] As can be seen from the above, the first information determination unit 301 of the intelligent rotation device of the multimedia playback device of the embodiment of the present application determines the first eye position information of the target user corresponding to the current multimedia playback device; then, when the target user is detected to have moved, the second information determination unit 302 determines the second eye position information of the target user after the movement; and the rotation unit 303 rotates the multimedia playback device based on the first eye position information and the second eye position information.
