Image sequence analysis for human body reconstruction
Fabio Remondino · Repository for Publications and Research Data (ETH Zurich) · 2002
The generation of 3-D models from uncalibrated image sequences is a challenging problem that has been investigated in many research activities in the last decade. In particular, a topic of great interest is the modeling of realistic humans, for animation, manufacture or medicine purposes. Nowadays the common approaches try to reconstruct the human body using specialized hardware (laser scanners) resulting in high costs. In this paper a different method for the three-dimensional reconstruction of human bodies from image sequences acquired with a standard video-camera is presented. The core of the presented work describes the calibration and orientation of the images but the whole process includes also the extraction of correspondences on the body using least squares matching and the reconstruction of the 3-D body model.
