Large-Scale Dense 3D Reconstruction from Stereo Imagery
In this paper we propose a novel method for largescale dense 3D reconstruction from stereo imagery. Assuming that stereo camera calibration and camera motion are known, our method is able to reconstruct accurately dense 3D models of urban environments in the form of point clouds. We take advantage of recent stereo matching techniques that are able to build dense and accurate disparity maps from...
متن کاملFlexible and User-Centric Camera Calibration using Planar Fiducial Markers
The benefit of accurate camera calibration for recovering 3D structure from images is a well-studied topic. Recently 3D vision tools for end-user applications have become popular among large audiences, mostly unskilled in computer vision. This motivates the need for a flexible and user-centric camera calibration method which drastically releases the critical requirements on the calibration targ...
متن کاملCamera Calibration for 3D Leaf-Image Reconstruction using Singular Value Decomposition
Features of leaves can be more precisely captured using 3D imaging. A 3D leaf image is reconstructed using two 2D images taken using stereo cameras. Reconstructing 3D from 2D images is not straightforward. One of the important steps to improve accuracy is to perform camera calibration correctly. By calibrating camera precisely, it is possible to project measurement of distances in real world to...
متن کاملCamera Calibration Error Analysis in Stereo Measurements
Camera calibration is an important and sensitive step in 3D environment reconstruction by stereovision. Small errors in the estimation of the camera parameters could rise to high errors in the 3D measurements, as the working distance increases. Therefore a method for analyzing the influence of each camera’s parameter error in the accuracy of the 3D measurement is compulsory in order to minimize...
متن کاملMulti-Camera Acquisitions for High-Accuracy 3D Reconstruction
In this paper we present our global approach to accurate 3D reconstruction with a calibrated multi-camera system. In particular, we illustrate a simple and effective adaptive technique for the self-calibration of CCD-based multi-camera acquisition systems. We also propose a general and robust approach to the problem of close-range partial 3D reconstruction of objects from stereo-correspondences...
