A new approach to map-matching and DR error calibration is proposed in this paper. This method compares the dead reckoning (DR) tracks and all possible route candidates in digital map to find out the best matching route through correlation analysis. It makes use of first order difference to decompose the rotation angle of track curve relative to candidate route curve. The DR sensor error parameters can also be calibrated with the matched routes on digital map. A case study demonstrates that the proposed map matching method is efficient and robust to noise.
