Based on Fuzzy Color Detection and Field Calibration for Robot Soccer

Machine vision system, which is an important part in robotic soccer. During the period of the competition, for real color, it is easily to cause the robot vision unable, for example, misrecognizing or error recognition under the different brightness. For solving this problem, we propose a fuzzy color detection to improve this problem in this paper. For examining the camera´s erection, the camera might not be set up in the center of the field. Therefore, it will cause the displacement problem in robot position and direction angle. In this paper, we propound a field calibration method to solve this problem. Finally, we illustrate an example, to demonstrate the proposed method can define the target color more accurate than existing method.
