METHOD AND DEVICE FOR DETERMINING QUALITY OF OFFLINE POSITIONING DATA

摘要

The present invention provides a method and device for determining the quality of offline positioning data. The method comprises: determining the coverage rate and/or success rate of offline positioning data according to an online positioning log on the side of a server and the offline positioning data, wherein the determining the coverage rate comprises: computing the total number X of records in the online positioning log within a set time period, computing the number Y of records, existing in an offline positioning database, of LAC identification information in the online positioning log within the set time period, and determining the coverage rate of the offline positioning data according to the ratio of Y to X; and the determining the success rate comprises: computing the total number X of records in the online positioning log within a set time period, computing the number Z of positioning results in the online positioning log within the set time period that are consistent with the offline positioning data, and determining the success rate of the offline positioning data according to the ratio of Z to X. By means of the present invention, the quality of offline positioning is measured according to the coverage rate and/or success rate of offline positioning data, so as to give guidance for optimization of the offline positioning data.
