Smartphone sensor based algorithms for Dead Reckoning using magnetic field sensor and accelerometer for localization purposes

摘要

Dead Reckoning has successfully been used as a navigational method in the maritime field for positioning between two fixed locations. This approach can be also implemented for smartphones using acceleration sensor and magnetic field sensor. The reliability of the compass values obtained is important in order to calculate the new position. Different tests of accuracy of compass readings of two different smartphones under various test conditions are presented. Moreover, the accuracy of the reconstruction of two walked indoor/outdoor paths using Dead Reckoning will be investigated.
