Real-Time Video-Based Modeling and Rendering of 3D Scenes
virtual reality, developing techniques for synthesizing arbitrary views has become an important technical issue. Given an object’s structural model (such as a polygon or volume model), it’s relatively easy to synthesize arbitrary views. Generating a structural model of an object, however, isn’t necessarily easy. For this reason, research has been progressing on a technique called image-based mo...
متن کاملFast 3D modeling from video
In this paper we build 3D models of rigid bodies from video sequences. The algorithm we use is simple and robust. It recovers the 3D shape parameters and the 3D motion parameters by first estimating the parameters of the induced optical flow representation. To estimate the 3D shape and 3D motion from the optical flow, we use a fast algorithm that is based on the factorization of a matrix that i...
متن کامل3d Reconstruction of Architectural Scenes from Uncalibrated Video Sequences
In this paper we present a system for three-dimensional reconstruction of architectural scenes from uncalibrated videos. These videos might be recorded using hand-held cameras, downloaded from the internet or taken from archival sources. Because we do not require prior knowledge of the camera’s internal parameters such as focal length, center of projection, and radial distortion we can deal wit...
متن کاملAutomatic Non-rigid 3D Modeling from Video
We present a robust framework for estimating non-rigid 3D shape and motion in video sequences. Given an input video sequence, and a user-specified region to reconstruct, the algorithm automatically solves for the 3D time-varying shape and motion of the object, and estimates which pixels are outliers, while learning all system parameters, including a PDF over non-rigid deformations. There are no...
متن کامل3D Face Modeling From Monocular Video Sequences
In this chapter we present two algorithms for 3D face modeling from a monocular video sequence. The first method is based on Structure from Motion (SfM), while the second one relies on contour adaptation over time. The SfM based method incorporates statistical measures of quality of the 3D estimate into the reconstruction algorithm. The initial multi-frame SfM estimate is smoothed using a gener...
