| 摘 要： | 针对常规实体地貌建模方法效率低且工作量大的问题提出一种基于控制点集的实体地貌辅助建模方法。该方法建立了控制地貌基本形态的等高线集合,根据实际建模需求确定内插控制插签点的数量及位置以引导地性线走向,并构建多级数据库存储、管理和调用建模数据。通过实验测试获得3组对比实验结果,对结果数据进行分析后提出实体地貌建模辅助决策方法。该方法能够在不同地貌建模需求下实现快速准确决策,提高建模效率。

| Abstract: | Aiming at the problem of traditional working method being inefficient and costing big workload before modeling,a landform assistant modeling method based on control point aggregate is put forward.It forms the contour line sets to control landform basic shape and form.According to practical modeling needs,interpolating control points' quantity and location are confirmed to guide landform trend.And it sets up multi-layer database to store,manage and invoke modeling data.Through experiment test,three groups of contrast results are obtained and analyzed to propose the landform assistant decision modeling method.T his method can make the rapid and accurate decision according to different landform modeling needs,thus raising modeling efficiency. |
