Abstract
A multiple-positioning-system switching and fused calibration method and a device thereof are provided. A first sensing device generates first sensing information, and the central processor calculates the first positioning information of a current position according to the first sensing information and a starting position, and downloads map information from the cloud database. A second sensing device detects a feature object, and obtains the distance information of the feature object and the current position, to the central processor. The central processor calculates a current position in the map information, and generates second positioning information, and performs fused calculation on the first positioning information and the second positioning information according to the weight values of a weight distribution table, to generate new first positioning information to replace the first positioning information. As a result, the positioning information generated by different devices can be fused to effectively calibrate positioning information.
