چکیده

In this contribution we firstly review some approaches to recover the 3D shape of human figures and the related movements. Then we present an improved and reliable version of an easy approach to recover 3D model of humans using just one frame or a monocular video sequence. A simplification of the camera model based on the collinearity condition is required, due to the absence of stereo view. This leads to a perspective or orthographic projection and requires additional information or constraints to solve the problem. The human figure is reconstructed in a skeleton form and visualized with the portable VRML language. Moreover a surface fitting is performed using a pre-defined 3D model obtained from laser scanner measurements.

3D Reconstruction of Human Motion and Skeleton from Uncalibrated Monocular Video

This paper introduces a new model-based approach for simultaneously reconstructing 3D human motion and full-body skeletal size from a small set of 2D image features tracked from uncalibrated monocular video sequences. The key idea of our approach is to construct a generative human motion model from a large set of preprocessed human motion examples to constrain the solution space of monocular hu...

3D Modeling for Capturing Human Motion from Monocular Video

This paper presents an approach to build a 3D human-body model from uncalibrated monocular video sequences. Using an orthographic projection model for the camera and a generic human body model, we constitute a 2D-3D conversion scheme to generate a 3D skeletal model from the 2D image domain. The complete 3D geometry and kinematics information of a human being can be extracted without any a-prior...

Human Skeleton Proportions Recovery from Monocular Data

This paper introduces a novel method for recovering the skeleton proportions for a human figure from monocular data. A perspective camera model is defined semi-automatically based on the user’s judgment. In the proposed method, key frames are first extracted from the source data automatically. A human skeleton model is then constructed to match all key frames under the established camera. An ad...

Markerless Motion Capture from Single or Multi-Camera Video Sequence

The modeling of human characters consists of two distinguished processes, namely the definition of 3D shape and 3D movement of the body. To achieve realism, both shape and motion information should be acquired from real persons. The two procedures are usually considered separately, by using full body scanners and motion capture systems. In this paper, we report about deterministic methods devel...
