Abstract: The optical system construction and working principle of intelligent north-finding gyroscope system based on CCD(Charge coupled devices) image sensor and computer technology are described. The common formula of transmit method of gyroscope direction and several math models of transmit in the environment of computer are given. It is proved to be effective through experimentation. The conclusions that intelligent north-finding method can change effects on the measuring results measured by people, improve the north-finding accuracy of gyroscope
