Method of correcting global position error |
摘要 |
Provided is a method of processing information on a tuple comprising latitude, longitude, and a timestamp collected from a position information collection device. The method includes changing a significant level value for calculating the statistical value of the speeds of past tuples in order to determine whether the current tuple has an error. |

1. A method of processing location information using values on a moving significant interval, the moving significant interval being generated in order to process information on a plurality of tuples comprising latitude, longitude, and timestamp collected from a position information collection device, by using a plurality of speed values on the plurality of tuples, the method comprising:
calculating an error rate regarding a collected set of tuples; converting a significant value included in a formula for calculating a value on the moving significant interval into a comparison value for comparing with the error rate; changing the significant value according to a result obtained by comparing the error rate with the comparison value; renewing the value on the moving significant interval by using the changed significant value and tuples collected in the past; and determining whether a newly collected tuple has an error or not, by comparing the renewed value on the moving significant interval with the newly collected tuple. |
