中文摘要: 在采用线结构光进行三维测量的过程中,将光刀图像细化后得到的骨架会出现许多毛刺和分枝,而光刀图像骨架的位置和形状将会直接影响到测量的精度,为了能够得到一条光顺并具有单一连通性的骨架,必须对其进行剪枝处理。为此提出了一种基于曲线追踪技术的剪枝算法,在分枝点处,根据光刀主干的走向找出分枝,从而快速有效的将这些分枝剔除,使最后得到的线条满足骨架的要求。实验表明,这种方法能有效地剪掉分支和消除伪特征,有利于最后三维重建的数据处理。
Abstract:There are a lot of burrs and branches after thinning the binary image of the light stripe, which will heavily affect the accuracy of the line-structure-light 3D shape measurement, so burrs and branches must be cut at first. A new pruning algorithm based on curve tracing was proposed, which can follow the backbone of the light stripe to find out the branches, and then eliminates branches and produce a high quality skeleton. The experimental results showed this algorithm can cut the branches and remove the false characters more rapidly and effectively, and lead to a good 3D reconstruction result.
