The control unit 340 performs various functions for the obstacle 300, and also performs processing and control for voice communication and data communication.
The communication unit 410 enables communication with a portable terminal, a computer, an unmanned air vehicle, or another server. More specifically, the communication unit 410 receives data on an image, taken by the unmanned air vehicle, from the unmanned air vehicle, and transmits processed data to the electronic scoreboard after the control unit 430 has processed the data. Furthermore, the communication unit 410 receives information, detected by the obstacle, from the obstacle, and transmits data on a calculated score to the electronic scoreboard after the control unit 430 has calculated the score.

More specifically, the control unit 430 processes data received from the unmanned air vehicle, and calculates the score of the unmanned air vehicle participating in a race based on data, received from the plurality of obstacles, according to a set algorithm.
First, as shown in
The image data processing unit 431 processes a taken 2D image, received from a plurality of unmanned air vehicles, into a 3D image.
The time calculation unit 432 calculates the racing time of the unmanned air vehicle having passed through the obstacles by using the time information of the unmanned air vehicle detected by the obstacles. For example, the time calculation unit 432 may calculate the overall racing time of the unmanned air vehicle by calculating the time that is taken by the unmanned air vehicle participating in a race to move from a starting obstacle 440 to a destination obstacle 450.
As another example, the time calculation unit 432 may calculate lap time between obstacle A 440 and obstacle B 450 by calculating the time at which the unmanned air vehicle passes through the obstacle A 440 and the time at which the unmanned air vehicle passes through the obstacle B 450, respectively.
The speed calculation unit 433 calculates the racing speed of the unmanned air vehicle having passed through the obstacles by using the speed information of the unmanned air vehicle detected by the obstacles. For example, the speed calculation unit 433 may calculate the speed at which the unmanned air vehicle passes through the obstacle A 440 and the speed at which the unmanned air vehicle passes through the obstacle B 450.
The direction calculation unit 433 calculates the racing direction of the unmanned air vehicle having passed through the obstacles by using the direction information of the unmanned air vehicle detected by the obstacles. More specifically, the direction calculation unit 433 may calculate the degree at which the unmanned air vehicle is tilted to the left or right while passing through each of the obstacles. For example, the direction calculation unit 433 may calculate the degree at which the unmanned air vehicle is tilted to the left or right with respect to each of the centers 441 and 451 of gates provided on respective set locations of the obstacle A 440 and the obstacle B 450 while passing through the obstacle A 440 or obstacle B 450.
The altitude calculation unit 435 calculates the racing altitude of the unmanned air vehicle having passed through each of the obstacles by using the altitude information of the unmanned air vehicle detected by each of the obstacles. More specifically, the altitude calculation unit 435 may calculate the altitude at which the unmanned air vehicle moves with respect to an upward or downward direction while passing through each of the obstacles. For example, the altitude calculation unit 435 may calculate the distance by which the unmanned air vehicle is spaced apart from each of the centers 441 and 451 of the gates provided at the respective set locations of the obstacle A 440 and the obstacle B 450 while passing through the obstacle A 440 or obstacle B 450.
The score calculation unit 436 calculates the score of the unmanned air vehicle participating in the race based on data, received from the plurality of obstacles, according to the set algorithm. More specifically, the score calculation unit 436 calculates the score of the unmanned air vehicle participating in the race based on the information calculated by the time calculation unit 432, the speed calculation unit 433, the direction calculation unit 434, and the altitude calculation unit 435.
An example in which the score calculation unit 436 calculates the score of an unmanned air vehicle when unmanned air vehicle C successively passes through obstacle A 440 and obstacle B 450 will be described below.
In the above-described example, when the unmanned air vehicle passes through the obstacle A 440, the score calculation unit 436 may acquire the racing direction and altitude information of the unmanned air vehicle when the unmanned air vehicle passes through the obstacle A 440 from the direction calculation unit 434 and the altitude calculation unit 435.
Thereafter, the score calculation unit 436 may connect the center 441 of the gate of the obstacle A 440, which has been passed through by the unmanned air vehicle, and the center 451 of the gate of the obstacle B 450, which will be subsequently passed through, with an imaginary rectilinear line 460, and may calculate the score of passage through the obstacle A 440 based on results regarding the direction and the altitude in and at which the unmanned air vehicle has passed through the center 441 of the gate of the obstacle A 440 with respect to the imaginary rectilinear line 460.
In other words, in an embodiment of the present invention, the set algorithm is an algorithm that connects the center of the gate of an obstacle, which has been passed through by the unmanned air vehicle, and the center of the gate of an obstacle, which will be subsequently passed through, with the imaginary rectilinear line 460 and calculates the score of passage through the obstacle 440 based on results regarding the direction and the altitude in and at which the unmanned air vehicle has passed through the center of the gate of the obstacle A 440 with respect to the imaginary rectilinear line 460.
The ranking determination unit 437 determines the ranking of the unmanned air vehicle participating in the race based on the score calculated by the score calculation unit 436.
In an embodiment of the present invention, when the unmanned air vehicle passes through an obstacle, not only a result regarding whether the unmanned air vehicle has passed through the obstacle but also a fact regarding whether the race is being performed by considering a direction and an altitude with respect to an obstacle through which will be passed subsequently are taken into account, and thus advantages arise in that the interest of a user operating the unmanned air vehicle may be attracted and the score of the unmanned air vehicle may be more accurately calculated.
There will be described an embodiment in which an unmanned air vehicle races along the track below. First, the unmanned air vehicle starts from a starting point (a starting obstacle) 511, sequentially passes through subsequent obstacles 512 to 517, and arrives at a destination point (a destination obstacle) 518, thereby terminating the race.
Although an example in which the single unmanned air vehicle races along the track has been described for ease of description in the embodiment of the present invention, it will be apparent that a plurality of unmanned air vehicles may race with one another along a track.
In this case, the starting gate 511 from which the unmanned air vehicle starts may provide notification of the start of a race by being opened as in the track of a horse racing park.
Furthermore, in this case, the plurality of guide bars 521 to 527 each configured to indicate the traveling direction of the unmanned air vehicle may be provided among the obstacles. Although the guide bars 521 to 527 may be provided among the obstacle, the guide bars 521 to 527 may not be provided according to the setting of a user.
The plurality of guide bars 521 to 527 may function not only to guide the unmanned air vehicle through the race but also to satisfy the sights of spectators who watch the race. Furthermore, although the plurality of guide bars 521 to 527 is intended to guide the unmanned air vehicle through the race, they may collide with the unmanned air vehicle during the race. Accordingly, the guide bars 521 may be made of the combination of hard material and also soft material.
In this case, the track is a variable track in which the shape in which the plurality of obstacles 511 to 518 and the plurality of guide bars 521 to 527 are arranged may be varied according to the setting of a user. More specifically, the track may be varied like train rails. For example, the track is a variable track in which the shape in which the plurality of obstacles 511 to 518 and the plurality of guide bars 521 to 527 are arranged may be varied by using a motor.
Furthermore, the track is made of a flexible LED obtained by combining soft material and hard material. For example, the track may be made by surrounding PVC with silicon and epoxy or resin.
Furthermore, the track is a variable track that may be used not only in an indoor area but also in an outdoor area. Furthermore, the track may be assembled in a module form, and may be easily reduced and extended. For example, when the size of an indoor area is limited, a user may reduce the track to fit the size of the indoor area and may then assemble the track. In contrast, when the size of an outdoor area is not limited, a user may maximally extend the track and may then assemble the track.
Although the 8-shaped track has been illustrated in
Furthermore, although the obstacles 530 are erected on the track, they are not limited thereto, but may float in the air in a portable form. Furthermore, the obstacles 530 may indicate the course of the unmanned air vehicle by the varying color of the obstacles 530. Furthermore, the obstacles 530 are provided with sensor units 540 in set regions of the obstacles 530, and thus detect the time information, speed information, direction information, and altitude information of the unmanned air vehicle that has passed through the gates. Although the obstacles 530 in which the sensor units 540 are provided along the edges of the gates have been described as an example in the present embodiment, they are not limited thereto, but the sensor units 540 may be provided in various regions, such as the upper side, lower side, left and right sides, etc. of the obstacles 530 according to the setting of a user.
For example, the electronic scoreboard may display an image taken by the unmanned air vehicle ranking first in a left region, may display the location of the unmanned air vehicle on an overall race course in a center region, and may display the current ranking of the unmanned air vehicle participating in the race in a left region.
Thereafter, at step S720, the plurality of obstacles detects time information, speed information, direction information, and altitude information when the unmanned air vehicle passes through the obstacles, and transmits data on the detected information to the server.
Thereafter, at step S730, the plurality of guide bars is located along the plurality of obstacles, and indicates the traveling directions of the unmanned air vehicle.
Thereafter, at step S740, the server processes the data received from the unmanned air vehicle, and calculates the score of the unmanned air vehicle participating in a race based on the data, received from the plurality of obstacles, according to the set algorithm.
Thereafter, at step S750, the electronic scoreboard receives the processed data and data on the calculated score from the server, and displays the 2D or 3D image, taken by the unmanned air vehicle, and the score information and ranking information of the unmanned air vehicle.
