Self-Calibration for Metric 3D Reconstruction Using Homography
نویسندگان
چکیده
In this paper, our goal is to reconstruct metric 3D models for large structures (or other 3D objects) from uncalibrated images. The internal camera parameters are estimated by using homographic constraints. More specifically, we propose to use straight lines and vanishing points to compute the infinite homography. However, because vanishing points are very sensitive to noise, we propose further constraints on homography with multiple image views. After obtaining the internal camera parameters, the metric 3D models can then be accurately reconstructed. Some preliminary results are presented in this paper.

Self-calibration of Varying Internal Camera Parameters Algorithm Based on Quasi-affine Reconstruction
This paper presents an method of self-calibration of varying internal camera parameters that based on quasi-affine reconstruction. In a stratified approach to self-calibration, a projective reconstruction is obtained first and this is successively refined first to an affine and then to a Euclidean reconstruction. It has been observed that the difficult step is to obtain the affine reconstructio...
متن کاملMixing Catadioptric and Perspective Cameras
We analyze relations that exist between multiple views of a static scene, where the views can be taken by any mixture of para-catadioptric, perspective or affine cameras. Concretely, we introduce the notion of fundamental matrix, trifocal and quadrifocal tensors for the different possible combinations of these camera types. We also introduce the notion of plane homography for mixed image pairs....
متن کاملA Novel 3D Reconstruction Approach from Uncalibrated Multiple Views Based on Homography
In this paper, we focus on a kind of 3D object shape reconstruction from images and put forward a metric approach to recover the object based on slicing planes by homography transformation and image consistency between multiple images. This approach done here eliminates the requirement for camera calibration, the estimation of the fundamental matrix, feature matches and pose estimation. We adop...
متن کاملExtrinsic Parameters Calibration of a Structured Light System via Planar Homography Based on a Reference Solid
− Structured light systems are widely used for three-dimensional shape reconstruction. The accuracy of the vision system parameters is of paramount importance for the accuracy of the 3D reconstruction. Often the extrinsic parameters change over time due to environmental conditions, in order to compensate for structured light parameters change, a self-recalibration method based on planar homogra...
متن کاملReconstruction Accuracy Assessment of Surface and Underwater 3D Motion Analysis: A New Approach
This study assessed accuracy of surface and underwater 3D reconstruction of a calibration volume with and without homography. A calibration volume (6000 × 2000 × 2500 mm) with 236 markers (64 above and 88 underwater control points--with 8 common points at water surface--and 92 validation points) was positioned on a 25 m swimming pool and recorded with two surface and four underwater cameras.
