The invention provides a positioning method and a positioning device of a carrying tool, the positioning method comprises the steps that the carrying tool is provided with a first sensor and a second sensor, and the positioning method comprises the following steps: filtering first sensing data from the first sensor by adopting a Kalman filter to obtain first sensing data; to obtain and record a queue of predicted data for positioning of the vehicle; and according to second sensing data from the second sensor and the time delay degree of the second sensing data, performing correction fusion on the prediction data queue to obtain a positioning result for the carrying tool. The positioning device comprises a filtering module, a correction module, a judgment module and a data removal module. The invention solves the technical problem that the sensor cannot accurately position and identify the motion state and position of the carrier due to the fact that the sensor cannot process, fuse and correct the delay of the
