The image acquisition unit 210 acquires a captured image from a plurality of photographing apparatuses installed in a stadium. Here, the plurality of photographing apparatuses are installed in a first photographing apparatus installed behind the home plate in the stadium, a second photographing apparatus installed outside the first or third base outfield in the stadium, and installed outside the first and third base infield. It may include a third imaging device. Accordingly, the image acquisition unit 210 captures the entire field, the image of the outfield side of the stadium, and the image of only the infield portion of the stadium from each of the first, second, and third photographing apparatuses. Can be obtained.

The image analyzing unit 220 analyzes the photographed image and extracts stadium coordinates for the stadium, defender coordinates for the defenders in the stadium, and attacker coordinates for the attackers in the stadium.

That is, the image analyzer 220 identifies the stadium, the defender, and the attacker from the captured image based on at least one of a motion, color, location, shape, or size of an object in the captured image. The stadium coordinates, defender coordinates and attacker coordinates may be extracted based on the positions of the stadium, defenders and attackers in the photographed image.

For example, the image analyzer 220 identifies the stadium, the defender, and the attacker from the captured image.

That is, the image analyzer 220 may compare the current photographed image with the previous photographed image, and identify the fixed object as a stadium when there is no movement of the object in the captured image. In addition, the image analyzer 220 may identify an object that does not have much movement as a defender when there is movement of an object in the captured image but is less than a reference, that is, when there is not much movement. In addition, the image analyzer 220 may identify an object having many movements as an attacker when the movement of the object in the captured image exceeds the reference, that is, when the movement is large.

In the example above, the stadium is stationary and stationary. Therefore, the defender and the attacker can be identified through the colors of the objects except the playing field, that is, the defender and the attacker.

That is, the image analyzer 220 identifies the colors of the remaining objects except the playing field among the objects in the captured image, searches for a color corresponding to each color of the remaining objects in the memory in which the color is stored, and matches the color. If there is, it is possible to identify whether the object is a defender or an attacker through identification information mapped to each of the matching colors.

Alternatively, the image analyzer 220 may detect the positions of the remaining objects except the playing field among the objects in the photographed image, search for a position corresponding to each position of the remaining objects in the memory where the position is stored, and match the positions. If there is, it is possible to identify whether the object is a defender or an attacker through identification information mapped to each of the located positions.

The image analyzer 220 may identify whether the object is a defender or an attacker using the information (shape, size, identifier, etc.) stored in the memory even in the case of the shape or size.

Meanwhile, when the defender and the attacker move, the image analyzer 220 extracts coordinates before and after the movement of the defender and the attacker by analyzing the photographed image, and uses the extracted coordinates before and after the movement. The change value of the coordinates and the attacker coordinates can be recognized. Accordingly, the image processor 230 may adjust the positions of the defender and the attacker in the relay assist image of the baseball game using the change value.

The image processor 230 may generate the relay auxiliary image through graphic processing using the stadium coordinates, the defender coordinates, and the attacker coordinates, and overlap the relay broadcast image transmitted from a broadcasting station.

That is, the image processor 230 may generate a graphic figure about the stadium using the stadium coordinates. Here, the graphic figure may be generated in a fan shape or a diamond shape. The image processor 230 may generate the relay assistance image by substituting the defender coordinates and the attacker coordinates into the generated graphic figure, and overlap the generated relay assistance image with the relay broadcast image.

In this case, the image processor 230 reduces and corrects the attacker's coordinates extracted from the image photographing only the infield part of the stadium among the captured images to fit the infield part of the graphic figure to substitute the graphic figure for the relay assist. An image can be generated.

Here, when generating the relay auxiliary image, the image processor 230 may express the defender and the attacker as at least one of a figure, an icon, a character, or an avatar. In addition, the image processor 230 may express the defender and the attacker in different shapes or colors when generating the relay auxiliary image. Thus, the viewer can distinguish between the defender image and the attacker image on the television screen.

For example, the image processor 230 may generate the relay assistance image by representing the defender as a circle and the attacker as a triangle. As another example, the image processor 230 may generate the relay auxiliary image by expressing the defender in yellow and the attacker in red.

The controller 240 may control overall operations of the baseball game relay broadcasting system 200, that is, the image acquirer 210, the image analyzer 220, and the image processor 230, according to an exemplary embodiment. Can be.
