A navigation errors correction method based on magnetic nail positioning is disclosed in present invention, which includes the following steps: (a).magnetic nail is set within the moving area of AGV, and an information-bearing magnetic field mode is established according to the magnetic field formed by said magnetic nail and stored in a navigation device; (b). Said navigation device in the AGV guides the movement of AGV; (c). Magnetic sensor on the AGV detects the features of magnetic field established by magnetic nail on the movement track; (d).Contrast features of magnetic field detected by magnetic sensor with those of magnetic field mode prestored by the navigation device, and reckon the relative position of magnetic nail and the AGV; (e).Based on the relative position of magnetic nail and the AGV, reckon the current position of the AGV; (f).Said navigation device adjusts the position and orientation of the AGV and guides the AGV to repair the movement errors based on the reckoning position of the AGV. The navigation errors correction method provided by the present invention compared to the prior art, has the advantages of precisely positioning, strong adaptability to environment and low cost in application devices.
