光照度对偏振三维重建效果的影响

The influence of illuminance on the effect of polarizationthree-dimensional reconstruction

利用偏振三维重建方法结合多尺度Shapelets算子,对表面具有高反射率、无纹理的不同复杂度物体进行三维重建,并重点研究光照度对三维重建效果的影响。实验结果表明光照度对偏振三维重建结果有重要影响:对于三维轮廓较简单和中等复杂的物体,高光照度有助于获得更清晰、准确的三维重建结果;对于结构较为复杂的物体,过高的光照度会掩盖物体的细节信息,过低的光照度则会导致轮廓信息丢失,实验表明最优的光照度范围为3.0~31.6 lx。合理控制光照度对获得高质量的三维重建结果至关重要。

The polarization three-dimensional(3D)reconstruction method combined with the multi-scale Shapelets operator was used to reconstruct different complex objects with high reflectivity and no texture on the surface for 3D reconstruction,and the influence of illuminance on the effect of 3D reconstruction was mainly studied.The experimental results show that the illuminance has an important effect on the results of polarization 3D reconstruction:for objects with simple and moderately complex 3D contours,high illuminance helps to obtain clearer and more accurate 3D reconstruction results;for objects with more complex structures,excessive illuminance will cover up the details of the object,and too low illuminance will lead to the loss of contour information.Experiments show that the optimal illuminance range is 3.0~31.6 lx.Therefore,reasonable control of illuminance is essential for obtaining high-quality 3D reconstruction results.
