Abstract
A positioning control method, suitable for an electronic device moving along with a vehicle, is provided in this disclosure. The electronic device includes an image-capturing module and a satellite-based positioning module. The positioning control method includes steps of: capturing a first image; extracting an icon object from the first image; capturing a second image; identifying the corresponding icon object in the second image; calculating a separation distance between the electronic device and the icon object according to a variance of the icon object between the first and the second images and a displacement distance of the vehicle; searching a point-of-interest (POI) corresponding to the icon object from a POI database; and, calculating/calibrating positioning data of the electronic device according to the separation distance and known coordinates of the POI.
