Structure from Motion 3 Three-dimensional Environment Measurement and Modeling with Feature Point and Straight-line in Omnidirectional Image Sequence

Three-Dimensional Environment Model Construction from an Omnidirectional Image Sequence

When mobile robots execute autonomous tasks, map information is important in path planning and selflocalization. In unknown environments, mobile robots must generate their own environmental maps. This paper proposes three-dimensional (3D) environment modeling by a mobile robot. The model is generated from results of 3D measurement and texture information. To measure environmental objects effici...

A Method for Reconstructing Structure from Omnidirectional View Sequence without Feature Matching

This paper describes a new method for directly reconstructing the 2D structure of an environment from image sequences taken by an omnidirectional camera moving on a straight line. By exploiting the characteristics of the omnidirectional images generated in an immersive way on both sides of the camera line, we synthesize a 3 0 visual representation of the environment. Slices of this volume direc...

Three-Dimensional Environment Modeling Based on Structure from Motion with Point and Line Features by Using Omnidirectional Camera

Accurate camera calibration and feature based 3-D reconstruction from monocular image sequences

In this thesis, computational methods are developed for measuring three-dimensional structure from image sequences. The measurement process contains several stages, in which the intensity information obtained from a moving video camera is transformed into three-dimensional spatial coordinates. The proposed approach utilizes either line or circular features, which are automatically observed from...

Comparison of the Lipophosphoglycan 3 Gene of the Lizard and Mammalian Leishmania: A Homology Modeling

Background: Lipophosphoglycan 3 (LPG3) is required for the LPG assembly, a well known virulent molecule. In this study, the LPG3 gene of the lizard and mammalian Leishmania species were cloned and sequenced. A three-dimensional structure (3D) for the target sequence was also predicted by comparative (homology) modeling. Materials and Methods: An optimization PCR amplification was performed o...
