Abstract
A distance measurement method based on moving coordinate positioning includes generating a calibration track adaptive to a predetermined route in a detection terminal; obtaining a real-time movement track of the detection terminal according to a moving coordinate positioning; and correcting a distance recorded by the detection terminal in real time according to a comparison result between the movement track and the calibration track. In such a way, the distance error recorded in the detection terminal can be corrected, thereby improving the accuracy.
