摘要
提出了一种时间维 相位重建的改进算法 :利用折叠位相图进行时间相位展开以提高算法效率 ;推导并调整了基于时间相位展开算法初始条件从而减少所需的二维编码条纹图 ,增加了算法的实时性 从而可以更加有效地解决深度表面不连续和存在隔离物表面拓扑结构的景物相位重建问题
An enhanced scheme for temporal phase unwrapping is presented Temporal unwrapping based on the wrapped maps is proposed to increase the efficiency The determination and modification of the initial condition is deduced to reduce 2D coded fringe patterns and increase the possibility of real time phase unwrapping. So it is solved better that the problem of phase unwrapping for the surfaces with discontinuous range data or the scene constructed by isolated objects. Experimental results prove the enhanced algorithm valid and feasible.
