Aimming at the problem of the field of robotics soccer system and the identification of robotics soccer, based on the seed point, this paper puts forward a method of field distortion correction, analyses the characteristic of different color tag design approaches, constructs a new color tag approach and its identification algorithm, rapid calibrating field and identifying robotics soccer are realized in high-confrontational, high-dynamic robotics soccer games. Through the trainning of FIRA Mirosot platform and actual games, the effectivity and reliability of this algorithm are proved and the need for real-time of robotics soccer system is met.
