- 2. Descriptions of the Related Art
- Casual and competitive dartboard games have been popular pastimes. The determinations of wins/loses and scores of the dartboard game are based on the ability of the players to throw darts onto the board-surface.
- In conventional dartboard competitions, the hitting points of the dart are determined artificially. As a result, the determinations of the errors caused by humans may factor in when calculating points, leading to a delay, especially during competition. In view of the above-mentioned drawbacks, certain types of electronic and automatically scoring dartboards have been developed. The electronic dartboards commonly found in the market mostly have a board-surface with different scoring blocks of the dartboard body that are separately packed, and each of the different scoring blocks is mounted with electronic sensors. When a dart is thrown onto the board-surface of the board body, one of the electronic sensors of that scoring blocks will sense the dart, and a corresponding score is automatically recorded via such a design.
- However, the above-mentioned conventional electronic dartboards mostly utilize plastic darts and porous grid-type board bodies. Such a design may interfere with the game because the darts being thrown at the grid-type plate position between the holes of the scoring region (or the boundary frame between the scoring regions) may fall out even through the dart is thrown within the correct positions on the dartboard. Furthermore, although conventional one-piece bristle board bodies employ thinner board-surface separation sheets as separators for individual scoring blocks to reduce the above-mentioned situation in which the darts are thrown at the frame but ends up falling out of the dartboard, in an international dart competition, to obtain accuracy and fairness of the competition, one-piece bristle board bodies are not mounted with any electronic sensing devices. Thus, the calculation and recording of scores have to be done manually. As a result, competitions are delayed and participants will often be distracted by the score calculations. To overcome the above-mentioned shortcomings, automatically scoring dartboard devices that are economic and practical are needed. In particular, the dartboard should sense the hitting points of the darts while not affecting the scoring accuracy, and automatically record and calculate the scores at the same time.
- As mentioned above, it is important to improve the automatically scoring system of a dartboard which could quickly determine the hitting points of the darts onto the board-surface. At the same time, the scores are calculated and recorded; and the automatically scoring system of a dartboard can be used on the board body made with of various material types.
- The primary objective of this invention is to provide an automatically scoring structure of a dartboard which comprehensively considers the speed, accuracy and fairness in score-calculation and that is applicable on board bodies made from various types of materials.
- To achieve the aforesaid objective, this invention provides an automatically scoring structure of a dartboard comprising a board body, at least two camera modules, a processing module and a display module. The board body has a board-surface. The at least two camera modules include respectively a first camera module and a second camera module. The first camera module captures a first image of the board-surface at a first angle, and the second camera module captures a second image of the board-surface at a second angle. The processing module is electrically connected to the at least two camera modules, while the first image and the second image determine a position of at least one dart, and the score is calculated based on the position of the at least one dart. The display module displays the identification of a participant, the score and other related information.
- According to the above contents, the automatically scoring structure of the dartboard can be disposed onto the board body made from any type of materials currently on the market. At least two camera modules are employed to rapidly and accurately determine the hitting points of the dart onto the board-surface at the same time, such that the participant could focus on throwing darts, and the dartboard competition could proceed smoothly and fairly.
