Embodiment 1
[0144] like Figure 4 As shown, a live broadcast system applicable to the present invention is introduced, including a chessboard base 1 , an image acquisition device 2 , a support frame 3 , a computer 4 , a projector 5 and a projection screen 6 . Chessboard pedestal 1 is used to place chess board, and support frame 3 is installed on chessboard pedestal 1, and image acquisition device 2 is fixed on support frame 3, and image acquisition device 2 is aimed at chessboard, and projection screen 6 faces projector 5 and lays, The image acquisition device 2 and the projector 5 are connected with a computer 4 . The image acquisition device 2 is used to collect images on the chessboard in real time and transmits the images to the computer 4. The computer 4 is used for automatic calibration of chessboard image coordinates, automatic detection of chessboard changes, automatic identification of chess pieces on the chessboard, and real-time display of chess pieces on the virtual chessboard...

The invention proposes an intelligent virtual live broadcast method for Chinese chess games based on machine vision. First, collect the static chessboard image, calibrate the coordinates of the chessboard, and establish the coordinate transformation relationship between the physical chessboard and the virtual chessboard; then, according to the position, name, color and other characteristic information of the chess pieces in the chessboard image, establish the state describing the comprehensive characteristics of the chessboard Information table; secondly, set the two-way baseline for chessboard state change detection, which is used for dynamic detection of chessboard changes; thirdly, obtain real-time change images of the chessboard, determine the properties of the changed chess pieces and their initial and target positions, and update the state information table in real time; finally, combined with chess The rules of the game realize the virtual live broadcast of the game process, including audio commentary, virtual linkage and game playback. Using the present invention can realize live virtual live broadcast of Chinese chess games. The method has the advantages of high reliability, strong adaptability, and convenient use. The present invention can also be applied to live broadcast of various chess games such as go and backgammon.
Description
technical field [0001] The invention belongs to the field of image recognition and intelligent information processing, in particular to an intelligent virtual live broadcast method for Chinese chess games based on machine vision. Background technique [0002] Chinese chess, which contains the traditional culture of the Chinese nation, is a kind of sports competition that people are keen on. Through inquiry, it is found that the live broadcast commentary of the existing large-scale chess game is that the host manually reproduces the chess game played by the players on an upright magnetic chessboard and explains it, without realizing the automatic intelligent live broadcast of the game. The design purpose of the present invention is to propose a method for intelligent virtual live broadcast of Chinese chess based on machine vision, so as to realize the intelligent virtual live broadcast of chess games. [0003] In the prior art, there are the following references: The documen...
