围棋棋局的光电识别技术研究

摘要:围棋棋局的人工判别与记录是一项耗时耗力而又极容易出现失误的工作。采用光电识别技术能有效地节省人力成本、提高效率。但现有的电子围棋棋盘存在黑、白棋子识别率不高，执子之手对识别存在干扰等问题。本文介绍了一种既能准确分辨黑、白棋子，又能排除手对识别干扰的新型围棋棋局识别系统。该系统由361个识别单元构成，每个识别单元能对应地完成棋盘上一个坐标点的光电识别。依据光强计算、稳定性计算以及棋子的最优材料的研究，该识别单元被设计出来。实测结果显示，这种新型的识别技术具有较好的稳定性并能去除手对棋子识别的干扰。结合最新的图像处理技术，围棋棋局的非人工判别与记录功能得以实现。

Abstract：The record of Go Chess is a time-consuming and labor-intensive job. Using photoelectric recognition technology can save labor costs and improve efficiency. However, the existing electronic chess board has a low recognition rate and the hand interference is hard to eliminate. This paper introduces a new Identification System that can accurately distinguish between black and white pieces and eliminate hand interference. The system consists of 361 identification units, each of which can correspondingly perform photoelectric recognition of a coordinate point on the board. The identification unit is designed based on the calculation of the light intensity, the stability, and material properties. The measured results show that this new recognition technology has very good stability. Combined with the image processing technology, the discrimination and recording of Go Chess is realized without manual operation.
