Abstract
(EN)
The invention relates to a map calibration method, a surveying and mapping mobile terminal and a surveying and mapping system. The map calibration method comprises the following steps: obtaining position information of n surveying and mapping points; obtaining location information of map points corresponding to the surveying and mapping points on an electronic map to generate matching pairs; generating calibration relationship of the location information of the map points and the surveying and mapping points according to the matching pairs; and obtaining calibrated map points according to thecalibration relationship. Map calibration can be realized according to a few mapping points, so that work efficiency can be improved faster, more efficiently and more effectively; route planning of aplurality of plots can be realized based on the calibrated map, so that the method is higher in efficiency; the method can realize accurate calibration of different electronic maps, and is high in applicability; and a user who has no professional operation skill can also realize surveying and mapping.
