Description

The present invention relates to an online competitive darts game, that is, a darts game in which each player plays a darts game via a communication means while being away from each other, and a live video transmission method for transmitting the throwing status of the throwing player to the other players. Further, the present invention relates to a camera system used for the live video transmission method.

In recent years, online competitive darts games that players can enjoy using communication means even when they are far away from each other have become widespread worldwide, especially in areas where going out has been restricted due to infectious disease countermeasures since last year. Demand is expanding in countries and other countries.

In this way, online competitive darts games have the great advantage of being easy to play because there are no restrictions on where to play, but on the other hand, there is basically no one around the player, and players usually gather in the same place. Compared to competitive darts games, it lacks a sense of presence and excitement, and tends to lack excitement.

On the other hand, in the live video of a professional darts player (hereinafter referred to as "professional player") battle, which is broadcast on TV, etc., depending on the situation of the game, in addition to the video of the throwing player and the score, the board surface Live images are provided on one screen at the same time, and the live images on the board surface are zoom images such as the entire image and the score area (single, double, triple, single bull and double bull areas) that should be aimed at in the next throw. While switching between and, the effect is made to give a sense of presence and exhilaration to viewers at a remote location.

Therefore, as shown in Patent Document 1 below, a CG (Computer Graphics) image is used to display a zoom image of the score area that should be aimed at in the next throw, a zoom image of a scene where darts are stuck in the score area, and the like. An online competitive darts game system that can be played is being developed.

Japanese Unexamined Patent Publication No. 2019-24717

According to the darts game system of Patent Document 1, the CG image of the entire image of the board surface, the zoom image of the score area to be aimed at in the next throw, and the CG image of the zoom image showing the darts hit status are switched and displayed. By doing so, it is possible to inform the waiting player of the result of the throwing and to liven up the game.

However, in the CG image, there is a high possibility that there will be a deviation from the actual darts hit situation, and in real time it is possible to accurately reproduce in what position in which score area the hit was made or not. It is very difficult to generate a CG image.

Further, the darts game system of Patent Document 1 is limited to electronic darts (soft darts), but if an attempt is made to apply it to hard darts, the darts hit position and hit status cannot be grasped in real time in the first place. , Even the generation of CG images is difficult.

In the invention of Patent Document 1, the above-mentioned generation and display of the CG image is necessary for improving the efficiency of data transmission / reception, and rather, the live image of the actual score area and the live image of the darts hit situation are photographed. (Patent Document 1 specification: paragraph [0051]).

On the other hand, when actually switching between the entire image of the board surface and the zoom image such as the score area that should be aimed at in the next throw, in principle, at least the camera that shoots the entire board surface and the zoom image are shot. A camera is required, and each camera that shoots zoomed images must focus on the score area to be shot. In any case, it is complicated and difficult for each player to prepare multiple cameras and focus on the score area to be zoomed by himself according to the game situation, and above all, it hinders the progress of the darts game. ..

The live video transmission method for online battle darts game and the camera system for online battle darts game according to the present invention drastically solve the problems of the above-mentioned conventional video transmission method and camera system, and throw a player with one camera. It is possible to display on the display of a player other than the throwing player, that is, a standby player, while accurately switching between the entire image of the board surface and the zoom image of the score area.

In short, the live video transmission method for an online battle darts game according to the present invention is a live video transmission in an online battle darts game performed by using a terminal with a darts board and a display provided by a plurality of players and a server connected to these terminals.

It can be carried out. As shown in FIG. 10, it is desirable that the server S is separately configured as a battle server Sb that performs game processing and a video chat server Sc that performs video distribution processing for efficiency.

The zoom zone setting means is a means for setting a plurality of zoom zones in the entire image taken by the board camera 4A. Here, the zoom zone is an area in the image, and means an image area that needs to be zoomed according to the game situation. Preferably, at least 20 fan-shaped score areas (single score area 1a, double score area 1c and triple score area 1d in FIG. 4) separated by a spider on the board surface and a score of a double circle in the center of the board surface. A zone in which each area (bull score area 1b in FIG. 4) can be visually recognized is set as a zoom zone. More preferably, the zoom zone is an area where the score number (a number representing the score written on the board) can be seen while making the triple score area or the double score area appear larger.

As a means for setting the zoom zone, as shown in FIG. 10, the application program 2b performs the zoom zone setting process in the main memory of the terminal 2A. The zoom setting process may be performed by automatically setting the zoom zone by a known image recognition means, or the entire image is displayed on the display 3A of the terminal 2A and the touch sensor unit 3a is displayed on the displayed overall image. The score area may be grasped by coordinate calculation by setting the upper, lower, left and right ends via the above, and the zoom zone may be set and processed based on the grasped score area. Even if the board camera 4A does not completely face the darts board 1A, the score area can be appropriately grasped and the zoom zone can be set by the coordinate calculation.

The zoom zone determining means is a means for selecting and determining the optimum zoom zone according to the game situation from the zoom zones set as described above, and this is also carried by the application program 2b. The optimum zoom zone is a zoom zone in which the score area at the position where the darts are hit by throwing can be visually recognized, or a zoom zone in which the score area to be aimed at at the next throw can be visually recognized. The score area to be aimed at in the next throw is automatically determined by the type of game, the score before throwing, and the darts hit position, but the score area at the position where the darts are hit by the throw is, for example, the score area to be aimed at. Targets the score area related to the hit position when the darts hit a different score area. The hit sensor unit 1f of the darts board 1A grasps the darts hit position, transmits the data of the hit position to the terminal 2A via the control unit 1g and the communication unit 1e, and the data of the hit position to which the application program 2b is sent. Then, from the type of game and the current score (score before throwing + score at the hit position), the score area to be noted in the next throw is decided, and the zoom zone where the score area can be grasped is decided.

The zoom means is a means for digitally zooming out the zoom image of the zoom zone from the entire image based on the determined zoom zone data (data such as coordinates, resolution, magnification, etc.) sent from the terminal 2A to the board camera 4A. , The camera module unit 4b and the control unit 4c of the board camera 4A.

The zone where the area and 1b) in FIG. 4 can be grasped is set as the zoom zone. More preferably, the area where the score number can be seen while making the triple score area or the double score area appear larger is set as the zoom zone.

≪Details of Step C≫
This is a step of transmitting the entire image to the terminal 2B of the standby player B. Specifically, as shown in FIGS. 6 to 8, the entire image is transmitted from the board camera 4A to the terminal 2A (step S1). Then, it is transmitted from the terminal 2A to the server S (video chat server Sc) (step S2), further transmitted from the server S to the terminal 2B (step S3), and displayed on the display 3B (step S4). Alternatively, the video is directly transmitted from the terminal 2A to the terminal 2B by the P2P communication method instead of via the server S (step S2'), the distribution load of the server S is reduced, and the video is smoothly transmitted.

≪Details of Step D≫
This is a step of selecting and determining a zoom zone in which the score area of the hit position can be visually recognized or a zoom zone in which the score area to be aimed at in the next throw can be visually recognized based on the hit position of the thrown darts and the score before the throwing. Specifically, as shown in FIGS. 6 to 8, when the darts hit (step S5), the hit sensor determines and grasps the hit position (step S6), and the data of the hit position is obtained by the terminal 2A. (Step S7). In the game processing (step S8) in the terminal 2A, the score area of the darts hit position by this throwing or the score area to be aimed at in the next throwing is determined according to the hit position, the game type, and the score before throwing. A zoom zone in which the score area can be visually recognized is determined (step S9). For the score of the throwing player A, a score based on the score before throwing and the score based on the score area of the darts hit position is calculated by the game processing (step S8), and the score data is transferred from the terminal 2A to the server S (step S8). It is transmitted to the battle server Sb) (step S22), transmitted from the server S to the terminal 2B (step S23), and the score is displayed on the terminal 2B (step S24). When the darts board 1A is for hard darts, the hit position is transmitted from the terminal 2AA of the scorer AA (step S7), or the throwing player A inputs the hit position to the terminal 2A, although not specifically shown. do.

≪Details of Step E≫
This is a step to cut out the zoom image of the determined zoom zone from the entire image by digital zoom. Specifically, as shown in FIGS. 6 to 8, the terminal 2A transmits the determined zoom zone data (data related to the position, resolution, magnification, etc.) to the board camera 4A, and the board camera 4A is based on the data. Cuts out the zoom image from the entire image by digital zoom (step S11).

≪Details of Step F≫
This is a step of switching the entire image transmitted to the terminal 2B of the standby player B to the cut out zoom image and transmitting it to the terminal 2B of the standby player B. Specifically, as shown in FIGS. 6 to 8, the board camera 4A switches the entire image to the zoom image (step S12), transmits the zoom image to the terminal 2A (step S13), and then the terminal 2A to the server. It is transmitted to S (step S14), and further transmitted from the server S to the terminal 2B. Alternatively, the zoom image is directly transmitted from the terminal 2A to the terminal 2B by a known P2P communication method, not via the server S (step 14'). In this embodiment, the board camera 4A is used to switch between the entire image and the zoom image, but for example, switching is also performed by the terminal 2A, depending on the implementation.
