Issue Date: | 2007 | Source: | 武汉大学学报. 信息科学版 (Geomatics and information science of Wuhan University), July 2007, v. 32, no. 7, p. 621-625 | Abstract: | 提出了一种基于最小二乘平差的数字地图合并方法,采用平差原理以求得实体调整合并后的空间位置。实验表明,与其他方法相比,该方法具有较高的精度,且较好地保持了原有实体的特征。 A new approach for map conflation based on least squares adjustment is presented.The constraints in map conflation are first derived,and the coordinates displacements of the conflated objects are then obtained by iterative adjustment computation.The results of the map conflation test show that the proposed method has a high precision and better ability to maintain the characteristics of the conflated objects compared with the exist methods. |
