Precision positioning method and device based on multiple pieces of position information

The invention relates to a precision positioning method and device based on multiple pieces of position information, and the method comprises the following steps: S1, building a regional map, and setting a plurality of position points in the regional map; S2, performing multidirectional positioning on a target located in the map area based on the plurality of position points to obtain positioningdata of the plurality of position points to the target, and S3, calculating a precision position of the target according to the plurality of positioning data. According to the precision positioning method and device based on the multiple position information, a multi-position-point positioning mode is adopted, when a certain position point breaks down, positioning of other position points to a target is not affected, positioning is stable, and high-precision positioning is achieved in a coarse and fine positioning combined mode. 本发明涉及一种基于多种位置信息的精度定位方法及装置，其方法包括以下步骤，S1，建立区域地图，在所述区域地图中设置多个位置点；S2，基于多个所述位置点对位于所述地图区域中的目标进行多
