A Visual Hull Algorithm of 3D Reconstruction Based on Interframe Coherence
The traditional volumetric visual hull generating methods were not applicable to real-time objects due to frame by frame calculations. A fast new algorithm based on interframe coherence was represented for fast reconstructing an object’s visual hull from its silhouettes in this paper. Utilizing frame to frame coherence of interframe visual hulls and motion estimation, the numbers of voxels that need to be calculated were adjusted dynamically without having to calculate all the voxels. The solution improved the time efficiency by decreasing the computation cost. The results of the experiments show that this generation algorithm is superior to some classical visual hull methods, as far as its reconstruction function for time complexity is concerned.
