摘　　要：介绍了基于CCD(电荷耦合器件)图像传感器与计算机技术的陀螺仪智能寻北系统的结构与工作原理,给出了中天法陀螺定向计算的一般原始公式以及在计算机环境下应用中天法的五个数学模型,通过试验证明其有效性。说明了智能化寻北方法可以改变测量结果对操作人员素质的依赖,降低测量的读数误差,部分提高陀螺经纬仪的寻北精度。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.
