最优几何匹配程序下重建时间连贯3D动画的研究

对RGB-D数据的三维重建进行优化,由此提出基于时间连贯的重建策略。在完成数据收集之后,对其中的RGB数据进行光学特征点的提取,由此获取两帧相互之间的初始系数3D关系。在对这些特征点进行细化时,则运用了最优几何匹配系统,然后利用特征点对连续帧的三维点云展开匹配,这个过程与帧分辨率独立;最后完成时间连贯的3D动画重建,具体是借助于运动向量对齐策略。通过实验得出,本文提出的策略能够对该3D动画进行重建。相较于其他方法,数据利用率更高,同时还有较高的精准度,在计算效率方面也具有一定优势。

Research on Rebuilding Time Coherent 3D Animation under Optimal Geometry Matching Program

The three-dimensional reconstruction of RGB-D data is optimized,and a reconstruction strategy based on time coherence is proposed.After the data collection is completed,the optical feature points are extracted from the RGB data,so as to obtain the initial coefficient 3D relationship between the two frames.When refining these feature points,the optimal geometric matching system is used,and then the feature points are used to expand and match the three-dimensional point cloud of consecutive frames.This process is independent of the frame resolution;finally,the time-continuous 3D animation reconstruction is completed.Specifically,it is with the help of the motion vector alignment strategy.Through experiments,it is concluded that the strategy proposed in this paper can reconstruct the 3 D animation.Compared with other methods,the data utilization rate is higher,and at the same time there is a higher accuracy,and it also has certain advantages in terms of calculation efficiency.
