Embodiment Construction

[0031] In the following description, numerous specific details regarding the systems and methods of the disclosed subject matter, the environments in which such systems and methods may operate, etc. are explained in order to provide a thorough understanding of the disclosed subject matter. Furthermore, it is to be understood that the examples provided below are exemplary and it is contemplated that other systems and methods exist within the scope of the disclosed subject matter.

[0032] The techniques described herein relate generally to three-dimensional (3D) reconstruction of two-dimensional images. 3D reconstruction can be performed with a system for establishing stereo correspondence between images to create a 3D shape representation of an object. The images acquired during such 3D shape acquisition may be of different quality depending on the optical properties of the object, and thus may affect the 3D data quality. Depending on how the object redirects light, some phys...

Abstract

In some aspects, the techniques described herein relate to systems, methods, and computer readable media for data pre-processing for stereo-temporal image sequences to improve three-dimensional data reconstruction. In some aspects, the techniques described herein relate to systems, methods, and computer readable media for improved correspondence refinement for image areas affected by oversaturation. In some aspects, the techniques described herein relate to systems, methods, and computer readable media configured to fill missing correspondences to improve three-dimensional (3-D) reconstruction. The techniques include identifying image points without correspondences, using existing correspondences and / or other information to generate approximated correspondences, and cross-checking the approximated correspondences to determine whether the approximated correspondences should be used for the image processing.
