中文摘要：

针对结构光条纹采样数据的特点,提出了一种自适应加权插值的新方法。此方法用一个可伸缩模板进行候选数据的提取,并根据模板伸缩度的大小对每个候选数据自适应地施以不同的权重。同时使用一种圆弧修正技术有效地克服插值中出现的削峰现象。实验结果表明,经自适应加权插值方法加密的数据用于三维重建,重建出的曲面光滑、逼真。

英文摘要：

In allusion to character of sampled data of structured light fringes,an adaptive weighed interpolation method was proposed.First,this method used a flexing templet in picking up candidated data.Then,different weight was adaptively added according to difference of flexed-degree of templet.During the interpolation process,an arc-correcting method was used to overcome the problem that peak value was cleared away in interpolation.The experimental results show that adaptive weighed interpolation method can make sampled data turn dense.Using interpolation results in 3D reconstruction,living and slick surface can be reconstructed.
