亥姆霍兹立体视觉是一种三维重建技术,通过利用亥姆霍兹互易来捕捉表面深度,而不依赖于材料的反射特性。在这篇论文中,我们感兴趣的是在透视立体成像的背景下,研究亥姆霍兹立体视觉在物体和一般场景的表面和深度轮廓方面的适用性。亥姆霍兹立体视觉通过交换光源和摄像机的位置来捕捉一对相互作用的图像。得到的图像对通过偏微分方程式将图像强度和场景深度分布联系起来。这个微分方程式的解取决于场景提供的边界条件。我们建议限制光源的照明角度,以便只成像相互可见的部分,从而产生稳定的边界条件。通过仿真和实验表明,对于包含多个遮挡对象的大类场景,该算法可以恢复出唯一的深度轮廓。
Helmholtz stereopsis is a 3D reconstruction technique, capturing surface depth independent of the reflection properties of the material by using Helmholtz reciprocity. In this paper we are interested in studying the applicability of Helmholtz stereopsis for surface and depth profiling of objects and general scenes in the context of perspective stereo imaging. Helmholtz stereopsis captures a pair of reciprocal images by exchanging the position of light source and camera. The resulting image pair relates the image intensities and scene depth profile by a partial differential equation. The solution of this differential equation depends on the boundary conditions provided by the scene. We propose to limit the illumination angle of the light source, such that only mutually visible parts are imaged, resulting in stable boundary conditions. By simulation and experiment we show that a unique depth profile can be recovered for a large class of scenes including multiple occluding objects.
