3D Reconstruction from Bifocus Imaging

摘要

This paper presents a method to reconstruct the three-dimensional model in monocular stereo vision. Depth can be obtained from monocular disparity in bifocus images. The stereo disparity results from lenses’ separation during imaging. Besides, 3D information can be acquired with depth and camera intrinsic parameters by means of camera calibration. Based on the characteristics of bifocus imaging, this paper develops a new method to detect and match feature, which fits monocular stereo vision much better. With only a pair of bifocus images and a calibrated camera, three-dimensional model of scene is constructed successfully.
