Chinese Chess The Embedded Visual Identification Algorithm And Program Development,

As an advanced technique, robot technology is currently very active. As with information technology it is extremely important strategic technologies with respect to strengthening industrial competitiveness. At present, the world, especially in the United States, Europe, Japan and other developed countries attach great importance to the robotics.With the increasingly wide applications of embedded system, intelligent robot vision system has new development direction. This paper combine embedded systems and machine vision,discuss machine vision systems based on embedded systems, has a systematic study of various methods of digital image process and get a software design from image acquisition module to the pattern recognition module.This article focuses on the intelligent chess robot vision and image acquisition system on board and pieces on the character recognition method. This paper will include:First, established the development platform. Because the structure and real-time DSP processing speed on the unique technical advantages, this paper, Beijing Triangle Electronics Technology Co., Ltd. to provide the SEED-VPM642 experimental box, in this development platform built image acquisition system to obtain the board the original image.By the board in the image, based on the collected images of the gray level transformation, filtering, sharpening, smoothing, binarization, and the marginalization of image preprocessing.In order to detect and identify pretreatment images, the paper analyzes the character recognition method for Chinese chess "will, like, persons, vehicles, horses, guns, pawn, handsome, phase, soldiers," the paper proposes using BP neural network classification character recognition method of Chinese chess, Chinese chess pieces to improve the recognition accuracy achieved good results.The established development platform based on the SEED-VPM642 image acquisition system for image acquisition and image preprocessing, detection board, pieces of Chinese character recognition method, the smart chess robot vision system is of great significance for further development and research intelligent chess robot, laid a good foundation.
