三维地形模型简化过程中存在着一系列简化误差,如何有效控制误差是保证简化模型精度的关键。在分析大量相关文献的基础上,对现有简化误差度量和控制方法的研究进展进行了详细介绍,在此基础上分析了该领域的发展趋势和今后的研究重点。为多细节层次地形模型建立和实时显示,提供理论和方法参考。 更多还原

【Abstract】 There are series of errors in the process of terrain model simplification,how to settle the error control is the key to ensure the terrain simplification model’s precision.Referring on a great deal concerned papers,introduced the development of the error control and error metric research,and analysised the direction and the emphases in this domain.Provided theories and methods to build and display the LOD of terrain. 更多还原
