查询词典 distributions

Firstly, because the triangle constrained matching propagation begins with the initial corresponding triangulations formed by a few seed points in the stereo pairs, this dissertation studies the affects of different numbers and different distributions of seed points on the image matching results through experimental analysis, and proposes a seed point selection strategy for different image texture conditions, an automatic selection algorithm is also designed that gives good distribution quality for a defined number of seed points.

首先，针对匹配传播过程中的种子点选取问题，通过实验分析研究了不同数量与分布的种子点所构成的初始三角网对匹配结果的影响，进而提出了不同影像条件下的种子点选取策略和一种自动提取一定数量、满足一定分布均匀度的种子点自动选取算法；其次，研究了海量数据情况下同名三角网的快速构建、数据组织存储与局部动态更新的方法；在此基础上，本文提出了随机传播、基于三角形拓扑关系的邻近传播和顾及纹理特征的自适应传播等三种传播策略，分别介绍了其详细的实现算法，并通过实验分析对这几种传播策略进行了比较，实验结果证明自适应传播方法在匹配的可靠性上最优。
