摘要: 随着摄影测量及机器视觉技术的迅速发展,对三维重构的普适性有了更高的要求。对于表面光滑、纹理单一甚至缺失的高反光非金属目标,传统的三维重构方法由于对纹理及反光特性的依赖使得此类目标的重构表面出现大面积的数据空洞。针对这一问题,本文提出了基于多光谱偏振的三维重构方法,将摄影测量与机器视觉进行融合,通过获取目标精确的偏振光谱特征实现准确的三维重构。该方法不依赖于物体表面的纹理信息,并且可以解决仅依靠菲涅尔理论无法实现天顶角和折射率同时估计的问题,最终实现天顶角和折射率的联合估计。由于杂散光和漫反射光在不同波段具有不同的偏振特性以及光谱特性,可完成对目标进行耀光去除的预处理,使得后期的三维重构的精度有较大的提高。基于偏振多光谱的目标三维重构方法是摄影测量与机器视觉融合后三维重构的引导性进展,具有更广泛的应用范围。

Abstract: With the rapid development of photogrammetry and machine vision technology,a higher universality of three-dimensional reconstruction is required.For high-reflective and non-metal targets with smooth surface or extreme simple texture,a large area of data void may appear on the reconstruction surface since the traditional 3D reconstruction methods depend on texture and reflective characteristics.To solve this problem,a 3D reconstruction method based on multispectral polarization imaging is proposed in this paper,which integrates photogrammetry and machine vision and achieves accurate reconstruction by obtaining accurate multispectral polarization characteristics of targets.The proposed method does not rely on the texture information on the surface,and it can solve the problem of joint estimating refractive index and zenith angle simultaneously,which cannot be achieved only by Fresnel theory.Due to straylights and diffuse reflection light have different polarization and spectral characteristics at different wavelengths,we can remove the highlight to improve the reconstruction accuracy.The 3D reconstruction method based on multiband polarization imaging is the guiding progress of 3D reconstruction after the fusion of photogrammetry and machine vision,which has a wider application range.

Key words: 3D reconstruction, multispectral polarization, textureless targets
