Abstract: Provided is an impact motion recognition system for screen-based multi-sport coaching. The impact motion recognition system for screen-based multi-sport coaching includes: a high-speed stereo camera device installed on an upper end of a target object including a hitting body and an moving body and configured to acquire a stereo image sequence in which the hitting body and the moving body are photographed; an object detection unit configured to detect an object in the acquired stereo image sequence; a moving body recognition unit configured to identify whether an impact motion has occurred in the detected object to recognize the moving body; a hitting body detection unit configured to, based on the moving body being recognized through the moving body recognition unit, detect the object excluding the moving body as the hitting body; a target object tracking unit configured to continuously detect a center point of the moving body and a feature point of the hitting body in a subsequent stereo image sequence using characteristics of the moving body and the hitting body that are detected, and continuously track the center point of the moving body and the feature point of the hitting body until the center point of the moving body and the feature point of the hitting body are not detected; and a motion analysis unit configured to analyze three-dimensional (3D) motion information of the target object using the center point of the moving body and the feature point of the hitting body, which are detected through the target object tracking unit, and high-speed stereo camera correction data.

Abstract: Provided is an apparatus and method for automatically recognizing an object by using a low-speed camera in a dual photographing mode, in which the apparatus includes an image acquirer and an image information analyzer. In the present disclosure, without using a separate motion sensor a movement state of a specific object during sports activities may be automatically recognized by using a successive photographing function of a low-speed camera in a dual photographing mode. Further, once an object starts moving, high-speed images in a multiple exposure mode may be automatically captured by using a high-speed photographing function of the low-speed camera in a dual photographing mode without using an expensive high-speed camera, and based on the captured images, movement information, including a movement speed and direction of the sports ball, the force and axis of rotation of the ball, and the like, is automatically analyzed to generate object movement information.

Abstract: Provided is a method of synthesizing 3D joint data based on a multi-view RGB-D camera. The method of synthesizing 3D joint data includes: converting joint data collected from a depth camera of each of a plurality of RGB-D cameras from a depth camera coordinate system of each of the RGB-D cameras to a color camera coordinate system of each of the RGB-D cameras; calculating a confidence level of the joint data converted to the color camera coordinate system using a 3D joint recognition algorithm based on the joint data converted to the color camera coordinate system; applying a rotation matrix and a translation vector to the joint data and converting the joint data to a predetermined reference coordinate system; and obtaining a weighted-average of the joint data converted to the reference coordinate system using a weight calculated based on the confidence level to synthesize the joint data.
