【摘要】 提出了多视觉环境下多重颜色一致性约束,解决了三维目标外形重建中颜色一致性的准确计算、目标外形完整性问题。将基于体素到视点距离的可见性分析加入到体重建过程中,只利用体素可见视点的信息计算颜色一致性,在数据源上保证颜色一致性计算的准确性;将体素颜色一致性最大约束与体素邻域颜色一致性最大约束联合,以解决由于颜色一致性阈值选取不当造成的体素"过剔除",即空洞问题。通过实验对比该算法与体素着色法的重建结果,证明该算法有较好的重建效果,并能有效地保证三维目标外形的完整性。更多还原

【Abstract】 A volumetric reconstruction method with multiple photo-consistency constraints is proposed in the multi-view construction environment.First,the visibility determination based on the distance between the voxel and the viewpoint is introduced to calculate the photo-consistency precisely.Then,multiple photo-consistency constraints are applied to eliminate those voxels which do not belong to the shape of the reconstructed object.The maximization of the photo-consistency constraint and the maximization of the neighbor photo-consistency constraint can be jointly used to reconstruct the effective shape in order to solve the "hole" problem induced by the unsuitable threshold of color-consistency.Experiment results demonstrate the effectiveness of the method in guaranteeing the completeness of the reconstructed shape by comparing with conventional methods.更多还原
