扫描数字化图质量的应变张量评估法

Quality Analysis of Digitalized Map By Using Strain Tensor

摘要: 引入了应变张量分析法表示数字化地图的质量,给出了应变张量的几何解释和计算方法,并以一幅实际数字化图为例,证明了地图数字化质量应变张量评估法的有效性。

Abstract: In this paper, the least square estimator of the strain tensor parameters is given. The geometrical meaning of the parameters is explained and analyzed. An example proves that the strain tensor representation for the quality of the digitalized map is effective.
