INDOOR POSITIONING SYSTEM AND METHOD BASED ON GEOMAGNETIC SIGNALS IN COMBINATION WITH COMPUTER VISION

摘要

To provide an indoor positioning system and method based on geomagnetic signals in combination with a computer vision.SOLUTION: An indoor positioning system includes: a map constructing module for combining computer vision coordinates and geomagnetic signal coordinates to generate a computer vision map and a geomagnetic data map; and a weighting module for calculating a computer vision weight and a geomagnetic signal weight on the basis of the constructed computer vision coordinates and the constructed geomagnetic signal coordinates, and substituting the computer vision weight and the geomagnetic signal weight on the basis of the weights in a weight equation to integrally estimate a present location.SELECTED DRAWING: Figure 1
