Title: | From D-RGB-based reconstruction toward a mesh deformation model for monocular reconstruction of isometric surfaces | Authors: | Hosseini, S. Jafar Araújo, Helder |
Keywords: | Isometric surface; 3D reconstruction; Range camera; Convex programming | Issue Date: | 2016 | Serial title, monograph or event: | Eurasip Journal on Image and Video Processing | Volume: | 2016 | Issue: | 1 | Abstract: | In this paper, we address 3D reconstruction of surfaces deforming isometrically. Given that an isometric surface is represented by means of a triangular mesh and that feature/point correspondences on an image are available, the goal is to estimate the 3D positions of the mesh vertices. To perform such monocular reconstruction, a common practice is to adopt linear deformation model. We also integrate this model into a least-squares optimization. However, this model is obtained through a learning process requiring an adequate data set of possible mesh deformations. Providing this prior data is the primary goal of this work and therefore a novel reconstruction technique is proposed for a mesh overlaid across a typical isometric surface. This technique consists in the use of a range camera accompanied by a conventional camera and implements the path from the depth of the feature points to the 3D positions of the vertices through convex programming. The idea is to use the high-resolution images from the RGB camera in combination with the low-resolution depth map to enhance mesh deformation estimation. With this approach, multiple deformations of the mesh are recovered with the possibility that the resulting deformation model is simply extended to any other isometric surfaces for monocular reconstruction. Experimental results show that the proposed approach is robust to noise and generates accurate reconstructions | URI: | https://hdl.handle.net/10316/102551 | ISSN: | 1687-5281 | DOI: | 10.1186/s13640-016-0114-9 | Rights: | openAccess |
