This thesis mainly deals with large scale objects of height around 1.5 meters. It uses a dynamic stereo model or a binocular stereo model to calibrate and reconstruct a 3D large scale object. This thesis briefly introduces two basic calibration techniques, i.e. DLT calibration technique and Tsai’s calibration technique. It then discusses and evaluates the impact of different factors on the cali...

Optimization tools have been developed for automatic calibration of water distribution models. The tools are often based upon a powerful genetic algorithm optimization and seamlessly integrated with hydraulic and water quality modeling systems. It provides the advanced features for engineers and modelers. In spite of the power of the GA modeling, some users report that the optimal calibration t...

BACKGROUND AND AIMS Data on the influence of calibration on accuracy of continuous glucose monitoring (CGM) are scarce. The aim of the present study was to investigate whether the time point of calibration has an influence on sensor accuracy and whether this effect differs according to glycemic level. SUBJECTS AND METHODS Two CGM sensors were inserted simultaneously in the abdomen on either s...

In the realm of multi-axial ratcheting, a step by step mathematical approach is developed for the parameter determination of decomposed kinematic hardening rules. For this purpose, key characteristics are mathematically derived for these hardening rules under multi-axial loading. These characteristics are then utilized to develop expressions which relate the loading history to the accumulated p...

Geometric camera calibration is a prerequisite for making accurate geometric measurements from image data and it is hence a fundamental task in computer vision. This article gives a discussion about the camera models and calibration methods used in the field. The emphasis is on conventional calibration methods where the parameters of the camera model are determined by using images of a calibrat...

Internal calibration greatly diminishes the dependence on calibration target deployment compared to external calibration. Therefore Electromagnetics Institute (EMI) at the Technical University of Denmark (TUD) has equipped its polarimetric SAR, EMISAR, with several calibration loops and developed a procedure calibrating the entire system except a few passive components which must be measured in...

STScI has continued the development of systems for HST data calibration. The calibration database system (CDBS) tracks information about all HST calibration files. CDBS has been rebuilt to be more automated and provide some additional capabilities for users. We have also begun investigating the requirements for an on-the-fly calibration system. This system would allow users to retrieve data tha...

The detection of plants based on a machine vision system is one of the most important parts of plants simulation. The calibration of the machine vision system is a basic step for nondestructive detection. We discuss common methods such as traditional calibration techniques, active vision based calibration techniques, and self-calibration techniques. The results show that it is feasible to apply...

In this paper, we present a GA (Genetic Algorithm) application for process model calibration. We propose a distributed GA-based calibration technique combined with the traditional local optimization algorithm, which reduces calibration time considerably. Experimental results on a PC cluster system (eight PCs) demonstrate that the calibration of 144 parameters can be completed within a few minut...

Camera calibration is a necessary and critical step in 3D object analysis. The accuracy of calibration results will affect the object’s position in world coordinates, especially for 3D object tracking. In this paper, we present a new camera calibration approach, and discuss its accuracy. We use 3D marks instead of 2D marks for calibration. Our experimental results show that our approach has the...
