Shadow supported building reconstruction

In this work we propose a technique for efficient extraction of multiviewpoint silhouettes using a single camera. To achieve this, we replace the cameras of a typical multi-camera setup with light sources and capture the multiplexed cast shadows. ...

In this paper, a novel method is proposed able to automatically generate accurate 3D models of both outdoor buildings and indoor scenes with perspective cues from line segments that are automatically extracted from a single image with an uncalibrated ...

Abstract--A new approach to computing a panoramic (360 degrees) depth map is presented in this paper. Our approach uses a large collection of images taken by a camera whose motion has been constrained to planar concentric circles. We resample regular ...
