• This measuring system is to recognize the log " s cross-section and the log " s axial profile in the image through the processing on the images, get the area value of cross-section and log length, so have the volume value by a certain formula for volume
  本系统通过处理原木图像，识别出图像中原木横截面和原木轴向廓形，从而计算出原木的横截面面积和材长，经一定的材积计算公式得出原木的材积值。
• To solve the inaccuracy problem caused by the two existing methods ( average end-area method and prismoidal method ) used for the calculation of roadway earthwork volume, this paper puts forward a new concept of the 3-dimensional algorithm that takes all the roadway geometric design procedures as a kind of geometrical operation between the ground model ( original terrain model ) and the roadway model ( designed model ) under certain constraints, and then presents a complete 3-dimensional algorithm of roadway earthwork volume as well as its executable computer program . the algorithm benefits from the re-triangulation technique of constrained delaunay triangulation ( cdt ), which can yield a true volume value theoretically . through a number of practical tests covering varied intervals between adjacent cross sections, it is proven to possess a higher accuracy compared with that of traditional methods . all the work involved in this paper indicates that the 3-dimensional calculation of roadway earthwork volume is feasible, more accurate and should have further application in practice
  针对目前广泛使用的道路土方量计算方法平均断面法和棱柱体法计算不准确的缺点,提出了三维土方量计算算法的概念.该算法以带约束的狄罗尼三角化(cdt)为技术核心,认为所有道路几何设计过程都是地面模型和道路(设计)模型进行几何运算的结果.基于此,本文设计出相应的算法步骤,同时完成了相应的软件开发,使得该三维算法能和传统的方法进行对比.此外,结合工程实例,采用了不同的道路横断面间距对三维计算方法和传统方法的误差进行比较、分析.结果证明三维算法具有更好的精度,该算法可用于道路、场地平整等工程土方量计算
