Study on Positioning Technology of Mileage Piles Based on Multi-Sensor Information Fusion
Mileage piles is an effective flag to pavement information positioning. However, the problems in positioning inaccuracies and error accumulation remain. By analyzing the primary errors in traditional mileage positioning, a positioning technology of mileage piles based on multi-sensor information fusion was proposed. This can avoid the accumulation of errors in every kilometer using GPS and road environment video. The gyroscope was used as a substitute when the GPS signal was missing and was also used to correct the swing error. The hectometer stake can be obtained by interpolating with the data of the photoelectric encoder. Experiments showed that the maximum mileage piles positioning error did not go over 1 m and the maximum hectometer stakes mileage piles positioning error did not go over 2.5 m.
