Description

[Technical field]

[0001] The present invention relates to a physical training support system, server, method and program, and more specifically, to a physical training support system, server, method and program that enable a user to confirm a series of movements in sports, etc., and provide training support. [Background technology]

[0002] In recent years, systems have been proposed for sports training, rehabilitation, etc., in which a subject is filmed from different angles and positions using multiple cameras, etc., and the subject's movements can be confirmed by the subject himself / herself. Students or players who wish to train, or patients undergoing rehabilitation, use such systems to improve their own skills or increase the effectiveness of their rehabilitation by viewing the filmed images or by comparing them with those of an instructor or model.

[0003] For example, an image processing device 10 has been proposed that aims to satisfactorily synchronize images captured from different angles by multiple cameras, and that includes an input device 15 for selecting image frames, and a CPU 11 that converts multiple groups of asynchronous images obtained by asynchronously capturing images of a subject H and a golf ball from multiple shooting directions, into still images for each of the multiple groups, displays a swing target extraction screen consisting of a "front still image" and an image advance gauge 30 on a display device 16, displays on a display means a swing image synchronization screen consisting of an "impact moment" of the "front still image" selected via the input device 15 based on the swing target extraction screen, a "rear still image", a "ball still image" and image advance gauges 40, 50, and associates the impact moment of the "front still image" with the "rear still image" and "ball still image" selected on the swing image synchronization screen as synchronized still images (see, for example, Patent Document 1).

[0004] Furthermore, with the aim of providing a dance apparatus that allows a player to check the degree of improvement in dancing, a dance apparatus 1 has been proposed that includes a central observation area 10C that is positioned facing the player P and where the player P observes an image of the player playing a dance, a right observation area 10R that is positioned to the right side X2 of the central observation area 10C and where the player P observes a model video 70a, and a left observation area 10L that is positioned on the other side of the central observation area 10C and where the player P observes a delayed video 80a that is a delayed video of the player P's play, and a control unit, in which the control unit plays the model video 70a in a loop in the right observation area 10R, and plays the play video of the previous loop as delayed video 80a in the left observation area 10L sequentially in synchronization with the playback of each loop in the right observation area 10R (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2013-169013 A [Patent Document 2] JP 2016-174637 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, the image processing device with multiple cameras in Patent Document 1 has a problem that, although it can effectively synchronize images taken from different angles, the person being filmed cannot view the images simultaneously or immediately, resulting in low training effectiveness. In addition, the dance device in Patent Document 2 has a problem that, although the player can view an image from the front of the player in comparison with the model video, the player or student cannot view images from various angles that they would not normally be able to see, resulting in little reference for training.

[0007] The present invention has been made in consideration of the above-mentioned problems in the conventional art, and aims to provide a physical training support system, server, method and program that allows a user to photograph himself / herself from a desired angle, obtain the image, and display it on a display after a certain delay, thereby enabling the user to check the image of himself / herself immediately after completing a series of movements without performing any special operations, thereby enabling the user to more efficiently improve his / her skills and increase the effectiveness of rehabilitation.

[Figure 9] FIG. 11 is a conceptual diagram of another example of the training support system according to one embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] Hereinafter, a physical training support system, a server, a method, and a program according to the present invention will be described with reference to the drawings. Note that the same reference numerals are used to indicate the same processes and configurations even in different drawings.

[0022] The present invention is for supporting training more efficiently by filming the training state by multiple cameras and checking the images when a student or player trains in a gym or sports facility. When implementing the present invention, the student or player who is the subject of the filming watches the filmed images, regardless of the presence or absence of a trainer who instructs the training. Conventionally, when training an action of moving the body according to a certain rule, such as training or training, filming the state by a camera and checking the image played on a display by the player himself has been recognized as having a certain effect as training to accurately reproduce the specified movement. Generally, even if an instructor or the like watches and points out the points that need to be corrected, the movement of the body cannot be seen by the naked eye of the person performing the movement, so unless the person himself sees himself in some way, such as in a mirror or by displaying the filmed image on a display in real time, effective feedback cannot be obtained and cannot be utilized in training. In addition, in normal cases, it is difficult to concentrate on checking whether the movement is accurate or not while performing the movement by looking at the mirror or the real-time image, so a method of playing back and checking the image filmed by the camera after the operation is completed may be used. However, when playing back the filmed footage at a later time, the act of playing it back after the movement is performed interrupts the flow of the series of movements and makes it impossible to check the movement while the sensation of having moved the body is still fresh. Instead, the player has to play back the footage while remembering the movement, which does not provide effective training.

[0023] The present invention performs a display delay as described below, and allows a person to check his / her own image immediately after each section of a series of movements during training or exercise without performing unnecessary operations such as playback, thereby more effectively supporting training or exercise. In the present invention, multiple cameras can be set in advance at desired angles and positions to take pictures, so that images from behind or above, which cannot be seen in a mirror, can be simultaneously checked on a single display.

[0024] The following describes a training support system for a specific sport, but the present invention can be applied to other sports and to a process of providing support for making it possible to execute a series of movements that move the body according to specific rules in a more rule-based manner other than training. For example, when a patient who has learned the movements to a certain extent performs rehabilitation alone at home, the present invention can be applied to provide support even without an instructor. Furthermore, the present invention can be used not only in gyms, gymnasiums, and other indoor facilities, but also outdoors as long as a camera for taking pictures and a display for displaying images can be installed.

[0025] (First embodiment) (System Configuration) In this embodiment, as shown in Fig. 1, a support server 101 that receives a plurality of video data acquired from each camera, synthesizes the data to be displayed on one display, and transmits the synthesized data to one display is connected to a network such as a LAN, and is connected to a plurality of cameras A111 and B112, each of which is directed in a predetermined direction from a predetermined position, and a display 121 via a network 103. In this embodiment, the functions of this server 101 can also be provided by a normal personal computer or a programmable processing board, as described later with reference to Fig. 7. In this case, the cameras and displays can be connected by wire or wirelessly using any standard known in this technical field, such as USB or HDMI (registered trademark), and can also be connected by a mobile phone line or a wireless network such as Wi-fi or BLUETOOTH (registered trademark), but is not limited to this.

[0026] In this embodiment, a camera A111 and a camera B112 are used as imaging means for imaging students or players who are subjects, and can be arranged in a desired position and direction for imaging the subjects by any method known in the technical field, such as by attaching them to a predetermined stand or tripod, or by installing them on a ceiling or wall. As the camera, various cameras and videos known in the technical field, such as a normal web camera, can be used, but the camera is not limited to this and any device that can image various subjects can be used.

[0027] FIG. 2 is a conceptual diagram of an example of a training support system according to an embodiment of the present invention. In this embodiment, darts is handled as a sport to be trained. As shown in FIG. 2, darts is a sport in which a player 201 throws a dart at a dart board 202 placed at a position several meters away, and the dart hits the target position on the dart board, and is usually played in a certain indoor dart play area. In this embodiment, a camera A111 that takes pictures of the player 201 from the front and a camera B112 that takes pictures of the player 201 from the side are placed at predetermined positions around the player facing the player. In this embodiment, two cameras are placed at the front and the side, but this is not limited to this, and more cameras can be placed at desired positions and at desired angles. For example, in addition to cameras A and B, a camera that takes pictures from above or a camera that takes pictures mainly from the hands can be added, but this is not limited to this, and more cameras can be used, or cameras can be installed and used outdoors.

[0028] The display 121 can be placed in a position where it is not an obstacle to throwing darts and can be viewed immediately, such as behind or beside the player 201 in the darts play area or nearby, but it can also be placed in any place outside the darts play area where viewing is easy. In this embodiment, images taken from two different directions are obtained by using two cameras, and the two images are synthesized and displayed side by side on one display 121, as shown in FIG. 3, with a front image 301 taken by camera A and a side image 302 taken by camera B. In general, in darts training or lessons, a person learns how to hold a dart, how to stand, and tips for throwing, as well as the rules. However, in the actual throwing action, the person can only partially recognize the movements of each part of the body with his or her own eyes, and each person has a different bone structure and muscle strength, so it is necessary to understand one's own body and create a "form that suits oneself" with an instructor, aiming for a throwing method that is optimal for one's body. In this embodiment, images taken from the front and side are used, but in addition to this, images taken from behind or from above can also be viewed, allowing the player to practice while immediately checking their throwing form each time they throw a dart, resulting in extremely effective training.

[0029] (Overall processing of this embodiment) The overall processing of one embodiment of the present invention will be described with reference to Fig. 4 to Fig. 6. Fig. 4 is a functional block diagram of an example of a server of one embodiment of the present invention, and Fig. 5 is a flowchart showing an example of the overall processing of this embodiment. Fig. 6 is a diagram for explaining the display delay of the training system of one embodiment of the present invention.

[0030] The support server 101 of the training support system of this embodiment includes an image acquisition module 401 that receives image data captured by the camera 111 etc., a display delay module 402 that executes processing to delay the display of the acquired image on the display, an image synthesis module 403 that synthesizes multiple image data obtained by capturing images by multiple cameras, and a video transmission module 404 that transmits the synthesized image data to the display 121.

[0031] The display delay time, which will be described later, is set to suit the player (step 501). Generally, the delay time tends to be shorter for advanced players because the series of movements required to throw a dart is shorter for advanced players than for beginners, but the delay time is not limited to this and can be set to suit the actual situation in which the player is being used. For example, the delay time can be set to 5 seconds or 10 seconds. The delay time can be set via a network in the case of a server, via an interface such as a keyboard in the case of a personal computer, or by connecting some kind of setting interface in the case of a processing board.

[0032] The cameras are continuously shooting, so when the player 201 throws a dart, each camera shoots and the images are acquired by the image acquisition module 401 (step 502). The acquired multiple images are synthesized by the image synthesis module 403 as shown in FIG. 3 (step 503). That is, in this embodiment, two cameras are used, so the images are synthesized so that two images can be displayed side by side on the display as shown in FIG. 3, but the invention is not limited to this and can be synthesized by any method known in this technical field, such as up and down or diagonally. Furthermore, the specific contents of the format of the image data acquired by the cameras and the method of synthesizing the image data can be any method known in this technical field.

[0033] As described above, the display delay module 402 adds a desired delay to the composite data obtained by synthesizing the multiple video data captured by the cameras in a desired manner, and the composite data is transmitted to the display 121 by the video transmission module 404 (step 505). That is, in the system configuration of this embodiment, if the data transmission delay process is not performed, the images captured by the cameras are synthesized in real time and displayed on the display 121, but the display delay module 402 processes the images of the player or student captured by the cameras and displays them on the display 121 with a desired delay. That is, by setting the delay time appropriately, the player or student can view the composite images of himself or herself captured from multiple directions before and after throwing the dart on the display 121 after throwing the dart, without performing any operation such as pressing a play button. As a result, the player or student can view the images from multiple angles immediately after actually throwing the dart, and can objectively judge his or her own form, thereby efficiently improving his or her skills.

[0034] In this embodiment, as described above, multiple images are synthesized and then subjected to delay processing, but this is not limited to this, and synthesis can be performed after delay processing, and any method known in this technical field can be used as long as synthesis and delay processing are performed finally. In this embodiment, two images are displayed side by side on the display as shown in Figure 3, but any number of images greater than or equal to two can be used as described above. For example, when four images are synthesized, they can be displayed by arranging images 801, 802, 803, and 804 from four cameras A, B, C, and D, respectively, as shown in Figure 8, but this is not limited to this, and they can be displayed in various forms.

[0035] (Delay Time Setting in This Embodiment) As described above, in this embodiment, by setting an appropriate delay time, a player or a student can objectively check his or her own form immediately after completing a series of movements. Here, the appropriate delay time can be calculated from the time from the start to the end of the series of movements to be performed. This point will be described with reference to FIG. 6. FIG. 6 is a diagram for explaining the display delay of the training system of one embodiment of the present invention. As shown in FIG. 6, if the first series of movements is from taking a stance to throw a dart to finishing throwing, and the time is action A1, and the playback time of the image of the subject during action A1 is D1, the subject cannot watch the display during action A1, and if the image D1 is displayed after a slight preparation time has elapsed from the end of the movement to standing up and facing the display after action A1, optimal viewing is possible. Therefore, the delay time T can be set by adding, for example, about 0.1 to 2 seconds as the preparation time P to action A1. Since action A1 varies from person to person, it is effective to set it individually, but since it tends to depend on the skill level of the player or student, the time can also be determined based on the skill level. Furthermore, the preparation time P can be set to a certain value depending on the installation conditions of each device in the facility, for example, the relative positions of the players or students and the display.

[0036] (Processing using a computer) As described above, in this embodiment, an example of processing using a support server has been described, but it can also be implemented by a personal computer without using a support server and a network. FIG. 7 is a diagram showing an example of using a personal computer instead of the support server of the training support system of one embodiment of the present invention. As shown in FIG. 7, in a support system 701 using a personal computer, a camera 111 and a display 121 are connected to a personal computer 702 via a LAN or other general-purpose or dedicated interface. In this case, the acquisition, synthesis, display, and delay of images are performed by a web application 703 running on the personal computer 702. Regarding the acquisition and distribution of images, a distribution software 704 can also be used. As described above, this embodiment can be provided by a compact system centered around a personal computer.

[0037] As explained above, not limited to darts, any movement in a sport, treatment, or other target sport can be set as a series of movements, and the delay time can be calculated according to the time required to execute each unit of movement. This allows the subject to look up at the display or turn around after completing each unit of movement, allowing them to directly and visually check their own movement from multiple angles, and thus correct their movement to make it more accurate.

[0038] Second embodiment This embodiment has a configuration similar to that of the first embodiment described above, and the functions and configurations of each device are also similar. In the first embodiment, the explanation was given on the premise of darts training, but in this embodiment, golf is used as the target sport. As shown in FIG. 9, when a golfer 901 practices swinging, three cameras 911, 912, and 913 can capture the motion of the subject 901 from the front, back, side, etc., and can display the composite images on the display 121. In this case, the golfer 901 can confirm his / her own swing after capturing the motion from the address to the finish as a series of motions. The delay time in this case is the time to perform the swing, but the preparation time added compared to darts can be set to 1 to 3 seconds, which is slightly longer. Therefore, in this embodiment, the delay time can also be calculated by adding the preparation time to the action time.
