[The present invention is] a dart game apparatus that provides a dart game in which one player successively throws n number of (n=3 or 4) darts D at a dart board 12, having: light sources LS that are disposed around the dart board 12 and emit lights L along the board face of the dart board 12; a plurality of photo-sensors S that are disposed around the dart board 12 at approximately the same height from the dart board 12 in the board thickness direction, and detect the brightness of the lights L emitted from the light sources LS; and a processor that calculates a hit position of a dart D in the dart board 12 based on the brightness of each light. A number of photo-sensors S is n2.

A calibration method for a camera which monitors a target board is disclosed, comprising steps: using the camera to capture a target image corresponding to the target board; using rotation and translation to align the target image to a reference standard and acquire the corresponding relationship of the target image and the target board; defining a region of interest above the target image; using at least one positioning marker in at least two positions of the target board, whose actual space coordinates are known, and using the camera to acquire at least two image coordinates of the positioning markers in the region of interest; and using the known actual space coordinates and the acquired image coordinates to work out the exact position of the camera. Thereby, the positions of the cameras can be used to correctly determine the positions of darts.

A data information integrated management system, particularly to an intelligent shooting training management system. The system includes a data acquisition apparatus, an operation terminal and a server. The operation terminal is connected with the data acquisition apparatus and the server. The data acquisition apparatus acquires a target paper image to obtain a photograph and a video record, and meanwhile, the data acquisition apparatus includes an automatic analysis module that analyzes a point of impact in the target paper image to obtain a shooting accuracy. The server manages the photograph, the video record, and the shooting accuracy. The operation terminal controls data exchange with the data acquisition apparatus and the server, and the operation terminal invokes and displays the photograph, the video record and the shooting accuracy.

An aerial vehicle is described that is capable of interacting within a TES environment, and capable of acting as a Ground Based Air Defense (GBAD) platform to represent virtually any type of aircraft in the simulation. The aerial vehicle may include sensors for determining its own location and/or orientation, and may further carry a payload of components that can be assembled modularly to equipped the aerial vehicle with different types of functionality. Such functionality can include enabling the aerial vehicle to gather information regarding its surroundings, engage with other military entities within the TES environment, and/or enable other military entities within the TES environment to engage with it.

A system for scoring darts that includes multiple cameras placed substantially parallel to the surface of a dartboard. With a field of view extending across the board, the cameras can be configured to capture images of darts projecting outwardly from the board as they are thrown, and the system can use this image data to calculate the location of each dart, and the corresponding score. Various algorithms may be used to orient the system and calibrate the system to account for irregularities in the images captured by the cameras to accurately determine the location. Proper scoring may be achieved for a variety of dartboards with different patterns of scoring regions based on game rules and corresponding board configurations maintained by the system.
