摘要
将罗德里格矩阵引入结构体变形参数提取中,首先对全局配准好的点云数据进行结构体特征点的提取,再利用提取的特征点基于罗德里格矩阵进行结构体变化旋转量和平移量的计算,从而实现变形参数的提取。通过对采集的数据进行实验,验证了该方法在结构体变形参数提取中的可行性。
In this paper, based on the theory of point cloud registration, Roderick matrix was brought in the extraction of the structure deformation parameters. Firstly, feature points of the point cloud which had been registered were extracted. Secondly, on the basis of Roderick matrix theory, rotation amount and translation amount of the structure were calculated to achieve the extraction of deformation parameters, using the feature points which had been extracted. At last, an experiment was designed to prove the feasibility of the method.
