Abstract
(EN)
A map calibration method, a mobile terminal for surveying and mapping, and a surveying and mapping system. The map calibration method comprises: obtaining position information of n surveying and mapping points (101); calculating to obtain position information of a map point on an electronic map corresponding to a surveying and mapping point so as to generate a matching pair (102); generating, according to the matching pair, a calibration relationship between the position information of the surveying and mapping point and the position information of the map point (103); and obtaining, according to the calibration relationship, a calibrated map point (104).
