一种动态稀疏式观测系统的场景重建方案
A Scene Reconstruction Scheme for Dynamical Sparse Mode Observation System
摘要
Abstract
For achieving the ability to dynamically observe and densely reconstruct the large-scale object in the scene, a method is proposed to reconstruct the scene by using a dynamical observation system, and a corresponding system solution is designed to implement the method. By using sparse mode data-updating method, the target of reduction of system burden can be achieved by maintaining the observed data which can reduce updating ratio. The outliers can be suppressed by selecting the inliers with the referenced plane. By subdividing the initial polygon model and applying the hybrid modeling method to fit the local surface of the model, the target of objective structure reconstruction can be achieved from sparse to dense. The result shows that, by applying the updating times can be reduced from 9 times to 6 times, the observed points can be reduced from 4 154 to 3 414 and corresponding outliers ratio can be reduced from 20.94%to 17.19%. Under the condition of twice subdivisions, the ultimate number of cells on model can be reduced from 86 712 to 71 631, which can reduce the system burden and achieve the better visual effect on reconstruction.关键词
