The invention relates to an omnidirectional mobile AGV navigation rectification method, which belongs to the technical field of McNamull wheel omnidirectional mobile AGV navigation and positioning. According to the invention, an information processing algorithm is used to analyze complicated actual situations into two kinds of simple situations which are independent and convenient to handle according to magnetic stripe position information fed back by front and rear magnetic sensors, which is convenient to handle; deviation correction is carried out for McNamull wheel omnidirectional mobile AGV characteristics; information fed back from the magnetic sensors is handled in real time and is used to calculate the deviation degree; the deviation correction speed is assigned according to the deviation degree; and high precision navigation rectification of the McNamull wheel omnidirectional mobile AGV is realized. The method is realized according to the driving characteristics of the McNamull wheel omnidirectional mobile AGV, and makes full use of the omnidirectional mobile characteristics of a chassis platform.
