In this work, we present a low-cost high-resolution structured light range scanner with automatic calibration, based on temporal stripe encoding. We present a novel single-step automatic active stereo calibration method, based on optimal backprojection estimation. We also present a method for estimating local fidelity of the range image and show how this information can be used to obtain sub-st...

Camera calibration plays an important role in the domain of the analysis of sports video. Considering soccer video, in most cases, the cross-points can be used for calibration at the center of the soccer field are not sufficient, so this paper introduces a new automatic camera calibration algorithm focus on solving this problem by using the properties of images of the center circle, halfway lin...

This paper describes a Reconfigurable Array for Machine Vision Inspection (RAMVI) that is able to produce spatially-accurate images combining information obtained from several cameras. Automatic camera calibration is essential for minimizing the changeover time required to reconfigure the array. This paper describes an automatic calibration method that uses a colour coded calibration grid (CCG)...

determination of volume change of unsaturated soils during loading and suction change is one of the most important difficulties in testing unsaturated specimens. it is revealed from literature review that various attempts have been made to invent an apparatus that can be used in testing on unsaturated soil specimens, simply and accurately. in this research, details of design and manufacture of ...

In optimization problems with at least two conflicting objectives, a set of solutions rather than a unique one exists because of the trade-offs between these objectives. A Pareto optimal solution set is achieved when a solution cannot be improved upon without degrading at least one of its objective criteria. This study investigated the application of multi-objective evolutionary algorithm (MOEA...

Back-analysis is broadly used for approaching geotechnical problems when monitoring data are available and information about the soils properties of poor quality. For landslide stability assessment back-analysis calibration usually carried out by time consuming trial-and-error procedure. This paper presents a new automatic Decision Support System that supports selection soil parameters three-di...
