triangulated irregular network meaning in Chinese
不规则三角网
Examples
- Study of triangulated irregular network andinterpolating terra in elevation in railway location
铁路线路三角网数模及地面高程内插系统研究 - The author introduces arithmetic from triangulated irregular network to regular square grid dem because the latter apply abroad than the former in fact
考虑到规则格网dem在实际应用中比tin更加广泛，介绍了从tin到规则格网dem的内插算法。 - According to geochemistry data and geochemistry work , i build a geochemistry digital model of triangulated irregular network , which can auto trace multi - work area and multi - hole by judging limited length
建立了适用于地球化学数据处理的不规则三角网数字模型，即多工区，多“洞”的自动生成不规则三角网模型。 - Thirdly , it utilizes line tracking and douglas - peucker line - simplification algorithm to realize the raster - to - vector conversion . a triangulated irregular network ( tin ) is constructed based on vector data , and dem point - array data is computed by interpolating grid on tin
第三,使用轮廓线跟踪算法和dpl多边形近似方法实现等高线数据的矢量转换;并基于等高线矢量数据建立不规则三角网,再内插格网生成dem点阵数据。 - After the paper sufficiently considered creation algorithmic of triangulated irregular network in time and space and analyzed three creation algorithms of tin - divide - conquer , triangulation growth , incremental insertion , the paper adopts to a new algorithm that takes advantages of divide - conquer and triangulation growth . it can create tin quickly . the paper also uses break lines , terrain feature lines , building borderlines to be restriction condition and creates triangulated irregular network based on restriction
综合考虑不规则三角网生成算法的时间和空间性能，分析了常用的三种tin生成算法：分割-归并法、三角网生长法和逐点插入法，笔者采用分割-归并法与三角网生长法相结合的算法，快速生成了tin ，并以断裂线、地性线、建筑物边界为约束条件，最终生成具有约束的不规则三角网。
