> 中文摘要: 本文着重研究三维体数据场基于整体对象数据表示及数据解释的物理构模问题.首先通过三维几何造型建立数据模型的几何表示,然后通过几何匹配的方法从数据场抽取出具有相同几何特征的曲面,以实现基于模型的数据场重构.本文还提出了一种快速B样条曲线离散生成算法,并据此提出了曲线控制多边形的估算方法,用于抽取数据场几何特征.
Abstract:This paper focuses on the problem of data representation and explanation of three-dimensional volume data field based on the physics model of the data.First the data model is set up by three-dimensional geometry model.Then the surfaces are extracted from the data field and match with the model to reconstructure the data field based on the Dhysics model.This paper also presents a subdivision algorithm to fast trace B-spline curve and the anti-approach iS adopted to evaluate the control polygon ot the curve in order to extract the geometry feature.
