Instant Surface Reconstruction for Incremental SfM
نویسندگان
چکیده
We propose an instant reconstruction of 3D surface meshes for a set of images and their camera poses and sparse 3D points computed by structure from motion (SfM). We aim at the proposed method to be compatible with an incremental structure from motion system as it can immediately generate the 3D surface model seen from the latest view point recovered by SfM. The proposed method consists of four steps: reference and target image selection adaptive to so-far recovered surface models; triangular patch initialization by taking into account the scene structures; fast 3D pose estimation of each triangular patch using inverse compositional image alignment (ICIA); surface generation by robustly refining the 3D triangular patches and integrating into pieces of surface meshes. The surface reconstruction results are shown on real image datasets of indoor as well as outdoor scenes and compared with the state of the art approach.

Multistage SFM: A Coarse-to-Fine Approach for 3D Reconstruction
Several methods have been proposed for large-scale 3D reconstruction from large, unorganized image collections. A large reconstruction problem is typically divided into multiple components which are reconstructed independently using structure from motion (SFM) and later merged together. Incremental SFM methods are most popular for the basic structure recovery of a single component. They are rob...
متن کاملIncremental Solid Modeling from Sparse and Omnidirectional Structure-from-Motion Data
This paper introduces a sparse and incremental 2-manifold surface reconstruction method. It uses a sparse 3D point cloud generated by a Structure-from-Motion algorithm (SfM) as its main input as opposed to the more common dense algorithms. Furthermore, our method is incremental: the surface is updated for every new camera pose computed by SfM, and the update occurs in a small neighborhood of th...
متن کاملSemi-Global 3D Line Modeling for Incremental Structure-from-Motion
Recovering 3D information from a single moving camera is a widely studied field in the area of computer vision (e.g. [1]). Most of these Structurefrom-Motion (SfM) approaches are based on so-called interest points (e.g. corners) in images, which can be accurately matched using powerful descriptors like SIFT [7]. Hence the output is usually a sparse 3D point cloud along with the camera poses for...
متن کاملRobust Feature Matching for Distorted Projection by Spherical Cameras
In this work, we proposes a simple yet effective method for improving performance of local feature matching among equirectangular cylindrical images, which brings more stable and complete 3D reconstruction by incremental SfM. The key idea is to exiplictly generate synthesized images by rotating the spherical panoramic images and to detect and describe features only from the less distroted area ...
متن کاملGlobal Structure-from-Motion and Its Application
Structure-from-motion (SfM) is a fundamental problem in 3D computer vision, with the aim of recovering camera poses and 3D scene structure simultaneously given a set of 2D images. SfM methods can be broadly divided into incremental and global methods according to their ways to register cameras. Incremental methods register cameras one by one, while global SfM methods solve all cameras simultane...
