It will be described in detail below.

The wired/wireless communication network 100 is a communication network that provides wired or wireless communication between the member terminal 200, the instructor terminal 300, and the online education server 400. When the wired/wireless communication network 100 is implemented as a wireless communication network, a wireless mobile communication network consisting of a base transceiver station (BTS), a mobile switching center (MSC), and a home location register (HLR) is provided. Can be used to communicate data. In addition, when the wired/wireless communication network 100 is implemented as a wired communication network, it may be implemented as a network communication network, and data communication may be performed according to an Internet protocol such as Transmission Control Protocol/Internet Protocol (TCP/IP).

The online education server 400 is a server that supports online education for non-face-to-face lectures, and has the same configuration as a typical web server in terms of hardware, and in terms of software, C, C++, Java, Visual Basic, Visual C It includes program modules that perform various functions by being implemented through various types of languages such as. In addition, it can be implemented using web server programs that are variously provided according to operating systems such as dos, windows, linux, unix, and macintosh in general server hardware. have.

The online education server 400, as shown in FIG. 2, includes a recruitment unit, a matching unit, a class reservation unit, an online education processing unit, an evaluation unit, and a management unit, and supports online education between instructors and members. . The matching unit receives the member's class request and matches the instructor.

In particular, the education processing unit of the online education server 400 of the present invention performs a function of providing images to the instructor terminal 300 and the member terminal 200, respectively, so that non-face-to-face education is performed online.

To this end, the education processing unit of the online education server 400 receives a member behavior image from the member terminal 200 and also receives an instructor behavior image from the instructor terminal 300. In addition, the shared video used for life sports education is transmitted to the member terminal 200 in real time along with the instructor's action video, and the same shared video transmitted to the member terminal 200 is transmitted to the instructor terminal 300 together with the member action video. Thus, online education can be achieved.

In the above, the term member action video refers to a video of a member taking an action class, such as yoga, taking a yoga posture following a yoga instructor, and the term instructor action video is a video of an instructor's yoga posture during a yoga lecture. This is true.

In addition, the above shared image is a reference image used in life sports education, for example, an image of a model taking a yoga action, which is a standard during yoga education. These shared images are stored and provided differently for each level. Shared videos for each level are stored in the storage of the online education server 400, and the storage unit includes a hard disk drive, a solid state drive, a flash memory, and As a module that can input/output information such as CF card (Compact Flash Card), SD card (Secure Digital Card), SM card (Smart Media Card), MMC card (Multi-Media Card), or Memory Stick, the inside of the device It may be provided in, or may be provided in a separate device.

The member terminal 200 is a terminal used by members who receive life sports training such as yoga training, and the drawing shows a smartphone as an example, but not only a smartphone, but also a desktop PC, a tablet PC, and A slate PC, a notebook computer, and the like may be applicable. Of course, the terminal to which the present invention can be applied is not limited to the above-described types, and it is natural that all terminals capable of online communication with external devices including a camera may be included.

The member terminal 200 transmits, to the online education server 400, an image of a member's behavior, photographed in real time, of a member taking a class. The lecturer's lecture action image and the shared video used as a reference video are received from the online education server 400, and the received shared video and the instructor's action video are simultaneously displayed on one screen as shown in FIG. 3. Therefore, members can take online classes while watching the lecturer's behavior video, which is the lecturer's education behavior, and the related education reference video, which is a shared video, thereby enhancing the educational effect.

Furthermore, the member terminal 200 may simultaneously display the member's own member's behavior image as shown in FIG. 4 in addition to the shared image and the instructor's behavior image. Therefore, the member does not need a separate mirror, and by watching the member's behavior video, it is possible to see in real time whether he is actually in a yoga posture that matches the instructor, and whether he is taking a yoga posture that matches the yoga posture of the model in the shared video. have.

The instructor terminal 300 is a terminal used by an instructor who conducts life sports training such as yoga training, and may be any terminal equipped with a camera such as a smartphone, a laptop computer, a desk PC, etc. and capable of external communication.

The instructor terminal 300 transmits, to the online training server 400, a video of an instructor's action photographed in real time of an instructor giving a lecture. In addition, a member's action image, which is a form of a member's yoga action, and a shared image identical to the shared image displayed on the member terminal 200 are received from the online education server 400, and the received shared image and the member's action image are displayed as shown in FIG. Display simultaneously in one screen. Therefore, the instructor can check the yoga posture of the member by comparing it with the shared video in real time using his instructor terminal 300, thereby increasing the efficiency of the lecture. Further, the instructor terminal 300 may simultaneously display the instructor's own behavior image as shown in FIG. 6 in addition to the shared image and the member behavior image.

Meanwhile, when the online education server 400 provides the same shared video to the member terminal 200 and the instructor terminal 300, it is necessary to extract and provide a shared video matching the current skill of the member.

For this, there can be two extraction methods as follows.

One is a manual extraction method in which an instructor selects a shared video matching a member. That is, the online education server 400 receives a shared video matching the level of a member from among a plurality of pre-stored shared videos for each level, and transmits the selected shared video to the member terminal 200 and the instructor terminal 300. For example, if the instructor judges that the yoga level of a student A is 5th grade, a shared video corresponding to the 5th grade is selected, and the selected 5th grade shared video is provided to both the member and the instructor.

The other is an automatic extraction method in which a shared image matching a member is extracted by a predetermined shared image extraction algorithm. The online education server 400 extracts a shared image matching a member's level from among a plurality of pre-stored shared images for each level, using a preset shared image extraction algorithm, and transmits it to the member terminal 200 and the instructor terminal 300. It is to do.

The shared image extraction algorithm compares and analyzes the member's behavior image and the shared image at the time of the most recent online video lecture for each synchronization point, and extracts a shared image to be used in education based on the result of the image comparison analysis.

Extracting the shared video to be used for education based on the result of image comparison analysis is to compare and analyze the image by synchronizing the shared video provided at the time of the most recent online video lecture and the member's action video, which is the video of the member's actions in the class. And, if the similarity between the member's behavior and the behavior of the shared image, which is compared and analyzed with the synchronized image, is less than the preset similarity standard, the same level as the level made during the most recent online video lecture is extracted as a shared image to be used for education. When the similarity between the synchronized image comparison and analysis of the member's behavior and the shared image's behavior exceeds the preset similarity standard, the next-level video from the level made during the most recent online video lecture is extracted as a shared video to be used for education. .

For example, assuming that the most recent online video lecture for the member A with the 3rd level was held 3 days ago, the image of the member's behavior 3 days before and the activity image of the 3rd level shared video are compared with each time point. The degree of similarity is extracted by analysis, and if the extracted similarity is less than 80% of the similarity criterion, the third grade shared video is still extracted as the shared video to be used for this education. On the other hand, if the extracted similarity is 80% or more of the similarity criterion, the next grade level 4 education video is extracted as a shared video to be used for this education.

If the yoga posture of the member taken during the previous training matches more than 80% of the yoga posture of the model of the shared video as the standard, it is determined that the yoga posture was excellent and the shared video of the yoga posture with the higher difficulty level of the next step is extracted. .

For reference, to extract similarity by comparing and analyzing images for each viewpoint, for example, assuming that each viewpoint is compared and analyzed for each viewpoint, the yoga pose of the model in the shared video provided at 13:45:00 and the same viewpoint The first degree of similarity is extracted by comparing and analyzing the member yoga postures identified in the member image at 13:45:00, which is the same. In addition, a second similarity is extracted by comparing and analyzing the yoga pose of the model in the shared video provided at 13:46:00 one minute later and the yoga pose of the member identified in the member video at the same time point at 13:46:00. . Similarly, each similarity is extracted every 1 minute.

These first, second,,,,,N similarities are calculated, and the average of the calculated first,2,,,,,N similarities is calculated to determine whether the average similarity value is 80% or more of the similarity criterion, and Therefore, it is to decide whether to extract the leveled-up shared video.

The embodiments in the description of the present invention described above are presented by selecting the most preferable examples to aid the understanding of those skilled in the art from among various possible examples, and the technical idea of the present invention is not necessarily limited or limited only by this embodiment. , Various changes and modifications and other equivalent embodiments are possible within the scope of the technical spirit of the present invention.
