Multi-website POI position mapping method and device

Abstract

一种多网站POI的位置映射方法及其装置。所述方法包括如下具体步骤:S110:建立纠正单元集合;S120:在纠正单元集合的每个纠正单元内进行区域拆分;S130:基于语义的控制点匹配;S140:多网站POI同名控制点集、检核点集自动、均匀获取;S150:位置映射模型系数解算;S160:位置映射精度评定。本发明均匀地将POI位置分成若干个单元,均匀选取控制点,综合利用语义匹配和最小二乘方法完全自动实现自动选取控制点,运用“分治”策略建立最优位置映射模型。
The invention relates to a multi-website POI position mapping method and device. The multi-website POI position mapping method includes the following specific steps: (S110) building a correction unit set; (S120) conducting area splitting in each correction unit of the correction unit set; (S130) conducting control point matching based on semantics; (S140) automatically and evenly obtaining a multi-website POI same-name control point set and an examination and checking point set; (S150) resolving coefficients of a position mapping model; (S160) evaluating the position mapping accuracy. By means of the multi-website POI position mapping method and device, POI positions are evenly divided into a plurality of units, control points are evenly selected, the control points are completely and automatically selected by comprehensively using the semantic matching and the least-square method, and the optimal position mapping model is built according to the dividing-and-conquering strategy.
