Dlt Based Aproach for Deformation Measurement
نویسنده
چکیده
Non-metric consumer cameras have become more and more advanced in the recent years. Their capability to measure deformations has been tested and described in the paper. Two preliminary experiments were conducted. In the first preliminary experiment a test of image matching and geometric accuracy was conducted. Based on that test, second preliminary test was conducted in which we tested three non-metric cameras, and their suitability to measure 3D deformations, by using the direct linear transformation. Based on the outcome of these tests, close range photogrammetry was used to measure deformations of longitudinally stiffened plated girders in a bending-shear interaction experiment. In this final experiment three non-metric cameras Cannon EOS 5 Mk II were used to calculate deformations, following a direct linear transformation.

In This paper a hybrid DEA method consisting of four phases for assigning the financial efficiency of commercial banks in India is used. This paper is based on panel data of banks for the period from 2011 to 2015. The DEA analysis based on hybrid method of DEA AND TOPSIS is used for ranking efficient Decision Making Units(DMUs) in Data Envelopment Analysis (DEA). However, since each of these me...
متن کاملExtended Kalman Filter-Based Methods for Pose Estimation Using Visual, Inertial and Magnetic Sensors: Comparative Analysis and Performance Evaluation
In this paper measurements from a monocular vision system are fused with inertial/magnetic measurements from an Inertial Measurement Unit (IMU) rigidly connected to the camera. Two Extended Kalman filters (EKFs) were developed to estimate the pose of the IMU/camera sensor moving relative to a rigid scene (ego-motion), based on a set of fiducials. The two filters were identical as for the state ...
متن کاملSystem Dynamics Aproach For Quantitative Risk Allocaion
Allocation of construction risks between clients and their contractors has a significant impact on the total construction costs. This paper presents a system dynamics (SD)-based approach for quantitative risk allocation. Using the proposed SD based approach, all the factors affecting the risk allocation process are modeled. The contractor’s defensive strategies against the one-sided risk alloca...
متن کاملDifficult Management of a Double-Lumen Endotracheal Tube and Difficult Ventilation during Robotic Thymectomy with Carbon Dioxide Insufflation
Robotic surgery with carbon dioxide (CO2) insufflation to the thorax is frequently performed to gain a better operative field of view, although its intraoperative complications have not yet been discussed in detail. We treated two patients with difficult ventilation caused by distal migration of a double-lumen endotracheal tube (DLT) during robotic thymectomy. In the first case, migration of th...
متن کاملA 3-dimensional Camera Calibration Algorithm for Underwater Motion Analysis with Refraction Correction Capability
INTRODUCTION The DLT (Direct Linear Transformation) algorithm, the most frequently used calibration algorithm, is based on the so-called collinearity condition; i.e. the object, image, and projection center form a straight line. This condition, however, does not hold in an underwater analysis setting due to the nonlinear image deformation caused by refraction at the water-air interface (Figure ...
