Efficient, Active 3D Acquisition, Based on a Pattern-Specific Snake
نویسندگان
چکیده
The paper discusses a structured light setup for fast, oneshot 3D acquisition. The projection pattern consists of equidistant, vertical stripes. The main problem is the determination of the stripe-boundaries. They are extracted with sub-pixel accuracy by a pattern-specific snake. An initialization procedure yields the rough contours. Sub-pixel accuracy is reached through an iterative relaxation process. The labeling problem is automatically solved if all boundaries are located. Interpolation guarantees that the correct number of boundaries is initialized.

Accurate protein function prediction is an important subject in bioinformatics, especially wheresequentially and structurally similar proteins have different functions. Malate dehydrogenaseand L-lactate dehydrogenase are two evolutionary related enzymes, which exist in a widevariety of organisms. These enzymes are sequentially and structurally similar and sharecommon active site residues, spati...
متن کاملA new 3D model retrieval approach based on the elevation descriptor
The advances in 3D data acquisition techniques, graphics hardware, and 3D data modeling and visualizing techniques have led to the proliferation of 3D models. This has made the searching for specific 3D models a vital issue. Techniques for effective and efficient content-based retrieval of 3D models have therefore become an essential research topic. In this paper, a novel feature, called elevat...

In this paper, a biologically inspired control architecture for a snake-like robot is proposed to achieve 3D locomotion and realize continuously free gait transition. Based on a novel central pattern generator(CPG) model, which is achieved from the perspective of network synchronization, the control architecture integrates three functional parts. First, following the convergence behavior of the...
متن کاملOne-shot pattern projection for dense and accurate 3D acquisition in structured light
This thesis focuses on the problem of 3D acquisition using coded structured light (CSL). CSL aims to retrieve the 3D information of an object shape by means of a camera or set of cameras and a coded active device that projects a pattern onto the scene. This pattern imposes the illusion of texture onto an object, increasing the number of correspondences even in presence of textureless surfaces. ...

This paper addresses the problem of rigid and non-polyhedral object tracking with a view to reconstructing 3D objects, without a priori knowledge on objects and on the camera motion. The outlines of our algorithm have been previously described in 4]. It is made up of a prediction step and of an identiication step based on active contour models. In this paper we focus on the identiication stage ...
