PROJECTION TYPE BILLIARD SYSTEM GESTURE/BILLIARD-ROD CONTROL SYSTEM AND IMPLEMENTATION METHOD THEREOF

摘要

A projection type billiard system gesture/billiard-rod control system and an implement method thereof. The system comprises an image capture device (7), a projection device (6) and a computer (3). The signal output end of the image capture device (7) is connected to the input end of the computer (3). The input end of the projection device (6) is connected to the output end of the computer (3) and controlled by the computer (3). A hollow billiard lighting lamp (4) and an infrared light supplementary lamp (5) are further provided. The method includes that the computer (3) controls the projection device (6) to project an operation interface comprising various function buttons in a system program on a table surface of a billiard table (8). The computer (3) controls the image capture device (7) to capture images in the scope of the table surface of the billiard table (8) in real time. Background comparison analysis and previous-frame comparison analysis are carried out on current images, and a changed image area in the images is further obtained. The part, close to the billiard table (8), in the changed area is set to be the initial end of the changed area, and the other end is the tail end of the changed area. When the residence time of the tail end in a certain function button area scope of the operation interface is longer than a preset time, it is considered that the button is clicked and selected by a user, and the computer (3) operates the corresponding system function.

主权项

1. A gesture/cue control system for projection billiards system, comprising: The computer (3), image acquisition device (7) of which the signal output end is connected to the input end of the computer (3), and projection device (6) of which the input end is connected to the output end of the computer (3) and controlled by the computer (3), wherein hollow billiards light (4) and infrared light supplement lamp (5) are also equipped; The lens of the image acquisition device (7) where a visible light filter is added, and of which the head end is aimed at the hollow part center of the hollow billiards light (4) and no under the bottom of the hollow billiards light (4) configured for capturing the image in the desktop of the billiards table (8); The infrared light supplement lamp (5) fixed on the hollow billiards light (4), of which lighting end is as high as the bottom of the hollow billiards light (4) configured for infrared lighting on the billiards table (8) and filtering the visible light in the image acquisition device (7); The system program in the computer (3) including that the control interface of all function buttons are projected on the desktop of the billiards table (8) through the projection device (6) to acquire real-time images captured by the image acquisition device (7) shone in the light of the infrared light supplement lamp (5), and compares and analyzes the current image with the background image or previous image through Open CV so as to get the changed area of the image and regard it as the moving gesture/cue area; that set the end near close to the edge of the billiards table in the changed area as the start of the change area and the other as the end, and it is regarded as that the button is selected by the user and the computer (3) runs the corresponding system function when the end stays in the function button area on the control interface over the preset time; The hollow billiards light (4) is at the top of the billiards table (8), so that the image acquisition device (7) is right in front of the center of the billiards table (8).
