Optimal fringe frequency allocation for non-standard phase-shifting profilometry
摘要
Abstract
In phase-shifting profilometry,the non-standard phase-shifting profilometry combined with the temporal phase unwrapping algorithm requires fewer fringe patterns,thereby achieving higher measurement efficiency.Since fringe frequency significantly affects measurement accuracy,we analyze phase errors in the temporal phase unwrapping of the non-standard phase-shifting profilometry and further evaluates its reliabil-ity.It was found that the reliability of phase unwrapping is closely related to the allocation of fringe frequen-cies.Consequently,we propose an optimal fringe frequency allocation strategy.Based on this strategy,we conduct comparative experiments on different frequency combinations of non-standard phase-shifting pro-filometry.Then the experimental results show that compared with the non-optimal frequency combinations of the 3fh1+2fh2+2fh3 heterodyne algorithm,the average error rate of the frequency combination proposed in this paper is reduced by 62.96%;compared with the non-optimal frequency combinations of the 2fh+2fm+3fl hier-archical algorithm,the average error rate of the frequency combination proposed in this paper is reduced by 49.23%.关键词
