Deflection angle correction method of tunneling system

The invention discloses a heading system deflection angle correction method, a heading system comprises a heading machine, a navigation assembly and a distance measurement assembly, the heading machine is provided with a walking assembly, and the navigation assembly comprises an inertial navigation element and a speedometer. The inertial navigation element is connected with the heading machine so as to be suitable for recording the real-time moving direction of the heading machine, the speedometer is connected with the walking assembly so as to be suitable for recording the advancing distance of the walking assembly, and the distance measuring assembly is suitable for measuring the distance between the heading machine and the side wall of a roadway. The method for correcting the deflection angle of the tunneling system has the advantages of being capable of correcting errors and high in precision. 本发明公开了一种掘进系统偏转角度校正方法，所述掘进系统包括掘进机，导航组件和测距组件，所述掘进机具有行走组件，所述导航组件包括惯性导航元件和里程计，所述惯性导航元件与所述掘进机相连以适于记录所述掘进机实时移动的方位，所述里程计
