The service server 110 stores the image in the data storage unit 120 and then requests the tracking information acquisition unit 130 to generate a tracking log. The service server 110 may be configured to independently store a plurality of images and appearance log data for the images by being connected to a separate file server.

The data storage unit 120 includes an image of a person to be learned, a dataset obtained by processing the image of the person to be learned, a learning model generated by deep learning the dataset, an image file, and an appearance log obtained by analyzing the image file. Save the data. The data storage unit 120 includes at least one storage, a DB server, or a file server.

The tracking information acquisition unit 130 decomposes the image downloaded from the data storage unit 120 into frames to extract the image of the character, and then downloads the image of the person who appears in each frame from the data storage unit 120 . It compares with the learning model to determine who it is, and according to the judgment, edits the character data for each playback section of the video to generate appearance log data.

The tracking information acquisition unit 130 is provided with a plurality of AI servers to enable parallel processing of data, and is configured so that at least one AI server can be selected according to the amount of data to be processed.

In addition, a plurality of AI servers share learning images and learning model files to learn new images for already learned people or learning images for new people, as well as to generate appearance log data through analysis of uploaded images. .

Each of these multiple AI servers processes the image to be learned according to the designed layer model, creates a dataset in a form that can be processed by the deep learning framework, and uses the deep learning framework to learn the dataset. An artificial intelligence learning daemon 131 that generates a learning model by performing the decomposition of the image downloaded from the data storage unit 120 into frame units to extract an image of a character, and the extracted image is stored in the data storage unit ( 120) by comparing with the downloaded learning model, and composing to include a tracking log extraction daemon 132 that generates the appearance log data by editing the result of the determination into data and then editing by section.

The network configuration of the service server 110, the data storage unit 120, and the tracking information acquisition unit 130 is a wired or wireless communication method as well as a direct connection method using an internal communication network or a remote connection method using an external communication network. It is possible to select at least one communication method necessary for network construction and configure it to provide an API (Application Programming Interface) suitable for the communication method so that data to be learned, processed data, or learned data can be shared. to improve accessibility between components.

In the embodiment of the present invention configured as described above, a person tracking task and a corresponding image service process will be briefly described with reference to FIG. 2 as follows. Here, the tracking task refers to the task of querying the AI engine for who is the person who appears in the image and converting it into data, that is, the image person matching task.

First, the tracking information acquisition unit 130 has an AI server, and pre-learns images of people.

After that, when the tracking information acquisition unit 130 registers an image while requesting generation of a tracking log from the service server 110, it extracts an image in units of frames through a tracking operation from the registered image to determine who the characters are by section and the results are converted into data to generate appearance log data.

The appearance log data format can be freely specified. In an embodiment of the present invention, the appearance log data includes a person identification ID, name, appearance point start time, appearance point end time, and appearance log number, for example, FIG. As shown in , it can be written in json format.

Thereafter, the tracking information acquisition unit 130 downloads and stores the appearance log data of the uploaded image in the data storage unit 120 , and transmits the completion of the tracking operation to the service server 110 .

Thereafter, the service server 110 transmits the corresponding image and appearance log data of the image to the client 140 when the client 140 requests image reproduction.

Accordingly, the client 140 displays the appearance time graph for each character and the information of each character in an area that does not interfere with video viewing while playing the image, thereby playing the image from the time of appearance of the character desired by the viewer, as well as playing the image. It allows you to check the information of the characters in real time.

In an embodiment of the present invention that operates as described above, an operation for providing detailed information of a tracking task, an appearance time graph, and a cast member will be described with reference to FIGS. 4 to 11 .

4 is a flowchart of a tracking operation process for extracting the appearance time of a character in an image in an embodiment of the present invention. As shown in this figure, when a tracking log generation is requested, downloading the corresponding image (S401) (S402) And, decomposing the downloaded image into frame units to extract a face image (S403), and comparing the extracted face image with a learning model to identify characters for each section of the image, and according to the identification result, the characters are identified. It includes a step (S406) of creating a star tracking log and a step (S407) of generating an appearance log data of an image based on the created tracking log, which will be described as follows.

First, the service server 110 requests the tracking information acquisition unit 130 to generate a tracking log in order to obtain the appearance log data of the registered image (S401).

At this time, the tracking information acquisition unit 130 provides the content registration API to the service server 110 to receive the information of the image for which the appearance log data is to be generated, and the information of the image is stored in the data storage unit 120 . stored and managed.

The form of the content registration API is exemplified as follows, and accordingly, content ID, content name, and the like are provided as parameters from the service server 110 .

http://api.co.kr:5401/tracking/insertContents

Here, the content ID is a content identification number managed by the service server 110 , and in an embodiment of the present invention, the content is an image.

Afterwards, the tracking information acquisition unit 130 determines at least one AI server to perform a tracking operation among a plurality of AI servers and instructs the generation of a tracking log, and the tracking log extraction daemon 132 of the selected AI server generates a tracking log Recognizing the job, the service server 110 downloads the image uploaded to the data storage unit 120 (S402).

To describe the image download process (S402) in detail, the tracking log extraction daemon 132 checks the content identification number of the image to be downloaded from the data storage unit 120 and requests the image storage location to the service server 110, Accordingly, the service server 110 provides the file location acquisition API of the form below, and this API is provided to the tracking log extraction daemon 132 after registration and is redirected.

http://URL/FileServerInfo?&contentID='contentID'

At this time, the service server 110 provides the image file location and port information in the form below through the contentID.

Result: {"server_ip":"111.96.29.47","server_port":8504}

Thereafter, the tracking log extraction daemon 132 uses the provided file location information to access the server where the image file is stored, and in an embodiment of the present invention, the data storage unit 120 to download the corresponding image file. The server 110 provides the following content download API, and this API is provided to the tracking log extraction daemon 132 after registration and is redirected.

http://IP:Port/FileDown?contentID='contentID'

When the image file for generating the tracking log is downloaded through the above steps (S401) and (S402), the tracking log extraction daemon 132 extracts one frame per second from the image file, and sets the frame extraction time as the file name to create a frame image. save as

At this time, the tracking log extraction daemon 132 extracts a face image from the extracted frame image (S403).

After that, the tracking log extraction daemon 132 compares the face image extracted above with a learning model obtained by deep learning the faces of people, and repeatedly performs the process of determining the character according to the comparison result for the entire image, , obtain the appearance time for each character using the person identification information and the frame number for the determined character, and record this in the tracking log file (S404 ~ S406). The tracking log file is a meta information log file in which the identification ID, name, appearance time, appearance log number, etc. of the character are recorded, and may further include thumbnail information and detailed information of the character.

Accordingly, the tracking log extraction daemon 132 performs the above process to generate the appearance log data as shown in FIG. 3 , and stores it in the data storage unit 120 while simultaneously generating the tracking log to the service server 110 is completed. A notification is made (S407).

Accordingly, the service server 110 transmits the corresponding image and appearance log data of the image when the image reproduction is requested from the client, and plays the image from the appearance point of the desired character while the client watches the image or appears in the current playback section. It allows you to check the details of the person.

On the other hand, in the embodiment of the present disclosure, the time graph display process for changing the playback position of the video being viewed includes the steps of reproducing the video according to the request of the client (S501), as shown in the flowchart of FIG. Checking whether the time graph icon displayed at the bottom of the viewing screen is clicked while streaming service (S502), and when the time graph icon is clicked, the person time graph for the character in the current playback section is displayed on the viewing screen (S503), Step (S504) of confirming whether a certain point on the time graph of a specific person is clicked, and if an arbitrary point on the time graph is clicked to view from the part where the specific person appears, the playback position is moved to the clicked point Playing an image in which the person appears (S505), checking whether a predetermined time has elapsed without clicking on the time graph in the above (S506), and moving the playback point to play the image or time When a certain period of time has elapsed without clicking the graph, a step (S507) of turning off the time graph displayed on the viewing screen is included, which will be described as follows.

First, the service server 110 provides the appearance log data of the video while streaming the corresponding video when there is a client's request for reproduction (S501).

At this time, a time graph icon and a character icon are displayed outside the image display area at the bottom of the viewing screen.

Therefore, when the client clicks the time graph icon with a remote device such as a remote control while viewing the video, the time graph for each character in the current playback section is displayed at the bottom of the viewing screen (S502) (S503). Although it has been described above that the time graph is displayed for the characters in the current playback section, it may be implemented to display the time graph of all the people appearing in the image.

At this time, as shown in the appearance log file of FIG. 3, the appearance section information of the character of the video streaming service from the service server 110 is a time unit, and the appearance start point and appearance end point are time units, in the embodiment of the present invention, ' It is expressed in 'seconds'.

However, in order to properly express the time unit indicating the appearance point on the user's screen, it is intuitive and easy to understand for the user to express where the appearance point (appearance start/end point) of the character is in the entire playback time of the video. .

Therefore, in an embodiment of the present invention, in order to express the time graph of the person appearing on the viewing screen in UI/UX, the time unit is converted into a % unit to show the appearance point of the character as illustrated in FIG. 6 , the appearance point block expresses it as

That is, in the appearance log data, the appearance start time and appearance end time of a character are calculated as a percentage (%) of the total playback time of the video, which is the appearance start time and end time in the total area of the time graph layer of the video playback screen. It is to find the corresponding point that matches the ratio (%) value of and to express the appearance section in the form of a block.

7 is an exemplary diagram of a time graph display screen for each person displayed on the viewing screen in the above manner in an embodiment of the present invention. The time graph for each person is basically in a hidden form so as not to interfere with video viewing, and when the time graph icon displayed on the lower control panel is clicked while watching the video, the person appearance time graph is displayed on the screen and exposed to the client.

Accordingly, when the client places the mouse on the appearing point block of the time graph displayed on the screen, a thumbnail of the character at the corresponding point is displayed, and when the client clicks the appearing point block, it moves to the corresponding appearing point and plays the video (S504) (S505) , is hidden from the screen by turning off the time graph display for each person displayed on the screen above (S507).

On the other hand, when the time graph for each person is displayed in the above, when a certain period of time has elapsed in a state where there is no click at the person appearing point of the time graph, the time graph display for each person displayed above is turned off and hidden from the screen (S506) ( S507).

On the other hand, when an arbitrary block in the time graph of a specific person is clicked in the above to change the playback position (S505) or when the playback section is changed due to video streaming, the previously searched appearance section data is deleted and a new appearance section is created. The search operation is repeatedly performed, which will be described as follows.

In general, when watching a video, the video is played in one direction unless there is a special action by the viewer. Therefore, since there is no reuse of information on the previously played section unless there is a special action by the viewer, it is better to exclude it from the search for the appearing section.

In an embodiment of the present invention, the service server 110 copies the appearance log data to a log search variable, and uses this log data to search for the appearance section of the character. By deleting the appearance log data of the previous appearance section, which is not the appearing section, and excluding it from the next search, unnecessary search is minimized in the real-time appearance section search to improve search performance.

That is, whenever the playback location is changed by activating a specific action such as skip or back by the viewer, the original appearance log data is copied back to the log search variable, and the video is played from the point the viewer moved while playing the video as described above. It repeats the search process for the appearance section.

When the above process is described with reference to FIG. 8, if the current video playback point is 37 seconds, when the service server 110 searches for a person appearing at the corresponding playback point, the appearance start time and appearance at the current playback point of 37 seconds are present. By reading the appearance log data corresponding to the appearance section between the end times, the character in the appearance log data is identified.

At this time, the search condition of the appearance section is to find the log data corresponding to the current playback point between the appearance start time and the appearance end time, and it is inefficient to search from the beginning to the end of the appearance section log data every time the appearance section is searched. If the appearance end time of the log data is data past the current playback point, it is excluded from the search target, and if the appearance start time is later than the current playback point time, the search is terminated, thereby minimizing the log search process.

That is, in the embodiment of the present invention, since the appearance log data for each character is arranged in chronological order, log data of the previous and subsequent appearance sections, not the log data of the current playback section, are excluded from the search target.

Accordingly, the service server 110 provides a time graph of the characters in the corresponding appearance section when the viewer clicks the time graph icon by searching only the character information of the current playback section while providing the video streaming service to be displayed on the viewer screen. That information can be provided immediately to the action of the viewer.

In addition, according to an embodiment of the present invention, information about a character in the current playback section may be provided in real time while a video streaming service is being provided.

9 is a flowchart of a character information display process in an embodiment of the present invention, and as shown therein, checking whether a character icon is clicked while providing a video streaming service according to a request of a client (S901) (S902) and , when the character icon is clicked, displaying thumbnails of the characters in the current playback section on one side of the viewing screen and confirming whether the thumbnails of the specific person are clicked (S903) (S904), and the characters even after a certain period of time has elapsed Steps (S905) (S906) of turning off the thumbnail display of the characters if their thumbnails are not clicked, and the steps of displaying information of the specific person when the thumbnail of the specific person is clicked (S907), and the thumbnails of the specific person When the display is displayed for a certain time or the playback section of the characters ends, the step of turning off the detailed information display of the specific character and the character thumbnail display (S908 ~ S910), which will be described as follows.

First, the service server 110 provides the appearance log data of the video while streaming the corresponding video when there is a client's request for playback (S901).

At this time, the time graph icon and the character icon are displayed in the control area located outside the image display area at the bottom of the viewing screen.

Accordingly, when the client clicks the character icon with a remote device such as a remote control while viewing the video, a thumbnail for each character of the current playback section is displayed on one side of the viewing screen in real time (S502) (S503).

In the present invention, in the video streaming service, appearance log data is searched every second to determine who appears in the current playback section, and a thumbnail of the determined character is displayed on the right side of the viewing screen as shown in FIG. , indicating that there are 3 characters in the current playback section.

Accordingly, when the viewer clicks the thumbnail of any person among the thumbnails displayed on the screen, the detailed information (profile) of the person is displayed on one side of the screen as shown in FIG. 11, and a progress bar ( progress bar) is displayed, and the appearance point of the character whose detailed information is displayed is displayed (S904) (S907).

11 exemplifies a screen on which a thumbnail of an arbitrary character is clicked and detailed information of the person is displayed in a state in which the time graph icon and the character icon are clicked to display the time graph and the thumbnail of the character in the current playback section. The thumbnail of the person may include location information on detailed information of the person.

If the time graph icon is not clicked above, the time graph is not displayed on the screen of FIG. 11 .

At this time, if the video is played and moved to the next playback section, the character of the previous playback section may not appear in the current playback section. In step S907, after displaying the detailed information of the specific person, the appearance section of the specific person is displayed. It is determined whether or not it ends (S908).

Accordingly, if the person whose detailed information is displayed above appears also in the current playback section and the display of detailed information of the specific person is not selected or a certain period of time has not elapsed after the detailed information is displayed, the detailed information of the person is displayed. to maintain the state of (S908) (S909) (S907).

In addition, if the person whose detailed information is displayed above appears in the current playback section, but the detailed information of the specific person is clicked or a predetermined time elapses after the detailed information is displayed, the person information display is determined to be off, the detailed information of the specific person is turned off (S908 ~ S910).

In addition, if the person whose detailed information is displayed does not appear in the current playback section in the step S907, it is determined that the appearance section of the specific person is over, and the detailed information display of the specific person is turned off (S908) (S910).

On the other hand, if there is no click of a specific person thumbnail even after a certain period of time has elapsed after the character thumbnail is displayed, the character thumbnail displayed on one side of the screen is turned off to hide it from the screen (S905) (S906).

In addition, even when a character icon is clicked while the character thumbnail is displayed or detailed information of a specific person is displayed, the display of the thumbnail or detailed information may be turned off.

Although the embodiment of the present invention has been described with reference to the drawings, this is illustrative and the present invention is not limited thereto, and various modifications and improvements can be made therefrom by those skilled in the art to which the present invention pertains. It should be understood that it is possible.
