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: A system and method for hologram synthesis and processing capable of synthesizing holographic 3D data and displaying (or reconstructing) a full 3D image at high speed using a deep learning engine. The system synthesizes or generates a digital hologram from a light field refocus image input using the deep learning engine. That is, RGB-depth map data is acquired at high speed using the deep learning engine, such as a convolutional neural network (CNN), from real 360° multi-view color image information and the RGB-depth map data is used to produce hologram content. In addition, the system interlocks hologram data with user voice recognition and gesture recognition information to display the hologram data at a wide viewing angle and enables interaction with the user.
