Title
Omnidirectional 3D reconstruction using rotating camera with mirrors
Abstract
Technology for capturing omnidirectional (360°) three-dimensional information in a real environment has applications in many areas, such as security with surveillance cameras, or the implementation of a complex sense of reality. In this paper, the authors propose an imaging device constructed of one camera and two flat mirrors and a technique for omnidirectional three-dimensional reconstruction using spatiotemporal volume. The proposed technique uses an imaging device with mirrors, whereby a large baseline length can be implemented without the use of multiple cameras and measurement precision can be improved beyond that of conventional methods using a single camera. Also, when capturing depth, a multibaseline algorithm using SSSD (Sum of SSD) is used to extract the trajectory for a spatiotemporal volume corresponding to the left and right mirror fields. Thereby, incorrect correspondences due to image noise or repeated pattern are reduced. Moreover, the influence of occlusion can also be reduced by separately evaluating the trajectory extraction results for the left and right mirror fields and selecting the good side. Experiments were performed using synthetic images and real images, an improvement in estimation precision with the imaging device was demonstrated, as well as the effectiveness of the proposed algorithm. © 2007 Wiley Periodicals, Inc.
