Recovering partial 3D wire frame descriptions from stereo data

چکیده
We describe the design of modules in the current version of the TINA stereo based 3D vision system responsible for the recovery of geometric descriptions and their subsequent integration into partial wire frame models. The approach differs considerably from that described in an earlier version of the TINA system [2, 3]. Our strategy for the construction of partial wire frame descriptions is broken into the following three processing stages:

متن کاملTINA: A 3D Vision System for Pick and Place
This paper provides an overview of the Sheffield AIVRU 3D vision system for robotics. The system currently supports model based object recognition and location; its potential for robotics applications is demonstrated by its guidance of a UMI robot arm in a pick and place task. The system comprises: 1) The recovery of a sparse depth map using edge based passive stereo triangulation. 2) The group...
متن کامل3d Object Reconstruction from Aerial Stereo Images
Among the variety of problems in providing 3D information about topographic objects, efficient data collection and model construction are issues for research. The efforts are directed towards improving the tedious, time and man-power consuming process of data generation by applying automation. In this paper, we present a semi-automatic method for acquiring 3D topologically structured data from ...
متن کاملRecovering Local Geometry for Time-varying Mesh from Motion
3D geometric modeling of real-world characters from multiview video is one of the popular topics in computer vision. In order to capture detailed and accurate 3D geometric model (Time-varying mesh), however, most proposed systems use only some static components(e.g. intensity, texture, color) of the generalized frames, e.g. photometric stereo method, stereo matching method. On the other hand, t...
متن کاملAdvances in 3D Model Identification from Stereo Data
Volumetric (CAD) models of objects are converted to a wire frame representation which is compiled into a data base and represented in vectors and matrices that characterise both local geometrical relationships and the structure of the models. This characterisation is independent of position and orientation and supports variable size. Using a stereo vision system, instances of these objects are ...
