Description

Technical Field [0001] The present invention relates to a positioning system using a beacon, a player image acquisition using a player positioning, and a player screen providing system,

The present invention relates to a system for measuring the position of a player / entertainer (hereinafter referred to as " player ") using the intensity of a beacon signal, a system for collecting a player- More particularly, at least three beacon receivers have their own coordinate values determined, and when only the distance between three beacon receivers and one beacon transmitter is determined, Since the coordinates of the beacon transmitter can be defined as the point at which the three circular trajectories meet by using the coordinate position registration system and other coordinate registration systems, the reception sensitivity of the beacon signal The packet necessarily includes beacon signal strength information (RSSI) in the beacon signal, and a unique UUID is assigned to the packet A single beacon receiver can measure the reception sensitivity of multiple beacon transmitters at the same time. The dedicated camera of each player is orientated to each player using player positioning, and the player-oriented video is collected, Screen.

In general, a sporting event relay transmits the progress of a sporting event to a broadcasting station through a plurality of relaying agents and relay equipment at a sports field, and a broadcasting station transmits a progress of a sporting event through a broadcasting receiver such as a TV or a radio It tells the situation.

In the case of relaying a sports game through TV, in the process of relaying a sports game, several cameras are arranged on the element elements of the whole stadium due to the size of the stadium and the characteristics of the game, and a relay screen is displayed. Therefore, viewers have no choice but to watch the relay screen decided by the broadcaster.

Particularly, when relaying an actual baseball game, only the portion of the ball having the ball is photographed and only the screen is relayed. Therefore, it is difficult to grasp the position and movement of the whole players with only the ball-centered relay screen.

For example, if a batter hits a hit, each defensive player moves to a position to respond to the situation. However, the game relay screen is focused on defenders who catch the batter or the ball, and viewers can not grasp the movement of other players.

Also, if a batter is attempting a bunt in a baseball game, or if the batter is a home run player, then the defenders change their defensive position accordingly. In this case, it is difficult for viewers to know the position change, movement or even the facial expression of the players unless the defenders' defensive position is changed according to the operation of the bishop or the game relay announcer does not explain it separately.

Meanwhile, Beacon is a core technology of IoT (Internet of Things), and accurate positioning can be achieved by using Bluetooth 4.0 (BLE) which consumes less power. If a similar concept of NFC can be recognized only by approaching the terminal within 5cm, the beacon can be utilized within a range of 70m, which is popular for promotional effect. In particular, beacon technology is already applied to the iPhone, and this technology is applied to the Android phone, so its application range is quite wide.

Therefore, there is an attempt to use beacon communication technology when positioning can not be performed using GPS because the accuracy is low.

If beacon communication technology can be used as a positioning sensor, it can be useful for locating a moving object within a certain space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of a beacon position, image collection, and screen providing system according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing the configuration of a system for tracking a position of interest according to the present invention.

1, the inventive positioning system 100 of the present invention includes a beacon transmitter 102 that is mounted on each athlete to generate and output a beacon signal, a plurality of beacon receivers 104-1, 2 and 3), and a player position detection server 110 for determining the position of each player using a beacon signal.

The athlete of the present invention describes the baseball player of a baseball field as an example, but is not necessarily limited thereto. A soccer player, a basketball player, or the like may be used as long as it is a sport in which a player moves with a position in a certain space where a plurality of beacon receivers 104-1,

Also, even a player can be an entertainer. When a singer singing or dancing on stage carries a beacon transmitter, the position of the entertainer is detected and thus the camera can be photographed mainly by the entertainer.

The beacon transmitter 102 may be installed on a player's clothing, hat, or the like. And broadcasts a packet containing information about the player to its surroundings. The beacon transmitter 102 is expected to extend the range of the device communication distance to about 70 m with Bluetooth 4.0 (Bluetooth Low Energy (BLE)) as a beacon technology in the past, and to expand to several hundred meters in the future.

Since the beacon transmitters 102 only transmit functions unlike conventional Bluetooth devices that require pairing and the beacon receivers 104-1, 2 and 3 also have only a receive function, a pairing process is not required, The required power consumption is also very small, which is suitable for the present invention.

The beacon transmitter 102 includes a beacon information part 102a, a packet generating part 102b and a beacon transmitting part 102c. The beacon information part 102a includes various kinds of information of the beacon transmitter 102. The packet generation part 102b generates a packet including information related to the beacon transmitter 102. The beacon transmission part 102c generates a packet, The beacon receiver 104 may broadcast the packet generated in the beacon receiver 102b.

FIG. 2 shows an example of a beacon signal including received signal strength information according to the present invention.

2, the beacon signal provided by the packet generator 102b includes a company identifier (2 bytes), a type (1 byte), a data length (1 byte) A unique user identifier (UUID) (16 bytes), a user setting ID (4 bytes), and beacon signal strength information (RSSI) (1 byte).

Here, the UUID information is generally identifiable ID information, and the user-set ID information is ID information that can be set by the user. Various information possessed by the beacon transmitter 102 via the beacon information unit 102a are UUID information or information Can be assigned to the setting ID information. Accordingly, different beacon transmitters 102 are assigned different UUID information, and the beacon receivers 104-1, 2 and 3 can recognize the beacon transmitters 102 through UUID information.

Received Signal Strength Indicator (RSSI) indicates that the beacon signal strength decreases as the distance between the beacon transmitter 102 and the beacon receiver 104 increases according to the friis'formula, The closer it gets, the more it increases. Equation (1) below can be used to determine the beacon transmitter 102 by calculating the relative distance between the beacon transmitter 102 and the beacon receiver 104 through the beacon signal strength value (dB).

The beacon receiver 104 receives the broadcasted packet from the beacon transmitter 102 to obtain a beacon signal and transmits it to the forehead position detection server 110 again. The beacon receiver 104 may use a smart device such as an iPhone or an Android phone instead of a dedicated terminal.

At least three beacon receivers 104-1, 2 and 3 of the present invention can be included.

3, beacon receivers 104-1, 3, and 3 may determine the location of beacon transmitter 102 by receiving a beacon signal with the same UUID information from beacon transmitter 102. As described above, the beacon signal includes beacon signal strength information (RSSI) in addition to the UUID information. The distance between the beacon transmitter 102 and the beacon receiver 104 can be calculated according to Equation (1) above.

The beacon receiver 104 may include four or more. The distance between the beacon transmitter 102 and the beacon receiver 104 is calculated as in the case of three beacons, but the average of the calculated distances is further calculated, and the average of the calculated distances is calculated by using the mean-square- It is possible to determine the calling position of the estimated beacon transmitter 102 to be the final calling position so that an average value is minimized.

1, the bow position detection server 110 includes a beacon information receiving unit 112 for receiving beacon information from beacon receivers 104-1, 2 and 3, and a beacon position calculating unit 106 for calculating a beacon position using beacon information A beacon position calculation unit 114, and a player position registration unit 116 for specifying and registering a player position using a coordinate other position registration system. Here, the beacon information includes at least UUID information and beacon signal strength information (RSSI).

FIG. 3 shows beacon signal strength information between three beacon receivers and one beacon transmitter according to the present invention.

Referring to FIG. 3, the first distance between the beacon transmitters 102 estimated through the beacon signal received by the first beacon receiver 104-1 may be represented by a first circular trajectory. That is, the first beacon receiver 104-1 becomes the center point of the first circular locus, and the first distance d 1 between the first beacon receiver 104-1 and the beacon transmitter 102 is set to be Thereby generating a first circular arc locus having a radius. If the reception sensitivity of the beacon signal is large, the radius of the arc locus will be small, and if the reception sensitivity is small, the radius of the arc locus will be large.

Likewise, the second and third distances d2, d3 between the beacon transmitters 102 can be indicated by an arc locus using the beacon signals received by the second and third beacon receivers 104-2, At this time, the first to third distances d 1, d 2, and d 3 correspond to the radius of each arc locus. When three circular trajectories are displayed as described above, there are overlapping points. The position of the player can be specified and registered by considering the point as a beacon position. At this time, the beacon receivers 104-1, 2 and 3 have fixed coordinate values and the beacon transmitter 102 has moving coordinate values.

For example, the coordinate value of the first beacon receiver 104-1 is determined by (x1, y1), the coordinate value of the second beacon receiver 104-2 is determined by (x2, y2) The distance d 1 between the first beacon receiver 104-1 and the beacon transmitter 102 is measured and the second beacon receiver 104-1 is measured when the coordinate value of the first beacon receiver 104-3 is set to (x3, y3) The distance d 2 between the beacon transmitter 102 and the beacon transmitter 102 is measured and the distance d 3 between the third beacon receiver 104-3 and the beacon transmitter 102 is measured, The coordinate value (x, y) can be calculated by triangulation using the following equations (2), (3), and (4).

Assuming that the beacon signal arrival distance is 70m, since the stretch baseball arena usually exceeds 100m, the beacon signal of all beacon transmitters 102 is received by at least three beacon receivers 104-1,2,3 Beacon receivers can be placed at regular intervals outside the baseball field. If three beacon receivers are installed in the baseball field, since a beacon signal may not be received at one beacon receiver 104, at least three beacon receivers 104, as shown in FIG. 4, As shown in FIG. If the beacon signal reaches a distance of several hundred meters according to the technical level, in case of a baseball field, all three beacon receivers 104 can receive all the beacon signals. On the other hand, the basketball or the volleyball can be operated by the three beacon receivers 104-1, 2 and 3 with only the current beacon signal arrival distance.

According to the coordinate position registration system of the present invention, since the beacon receiver 104-1 has its own coordinate value (for example, x1, y1) already determined, the three beacon receivers 104-1, When only the distance between one beacon transmitter 102 is determined, an arc locus originating from each beacon receiver 104-1, 2, 3 can be determined, and a point at which the beacon receiver 104-1 is located can be determined as the coordinate value of the beacon transmitter 102 .
