Reconstruction Error of Calibration Volume’s Coordinates for 3D Swimming Kinematics
The aim of this study was to investigate the accuracy and reliability of above and underwater 3D reconstruction of three calibration volumes with different control points disposal (#1 - on vertical and horizontal rods; #2 - on vertical and horizontal rods and facets; #3 - on crossed horizontal rods). Each calibration volume (3 × 2 × 3 m) was positioned in a 25 m swimming pool (half above and ha...
متن کاملKinematic Analysis of the Reconstruction Error of A Calibration Volume for 3d Analysis in Swimming
The purpose of this study was to assess the accuracy and reliability of the three-dimensional reconstruction above and below water of a calibration volume for three-dimensional analysis in swimming. The calibration volume (3x3x3m) was placed in a 25m x 12.5m x 2m swimming pool and was recorded simultaneously by 4 under and 2 above water synchronized cameras. To assess the number of control poin...
متن کاملCalibration for 3D Reconstruction of Thermal Images
The calibration system presented in this article enables to calculate optical parameters i.e. intrinsic and extrinsic of both thermal and visual cameras used for 3D reconstruction of thermal images. Visual cameras are in stereoscopic set and provide a pair of stereo images of the same object which are used to perform 3D reconstruction of the examined object [8]. The thermal camera provides info...
متن کامل3D reconstruction of octopus arm swimming motion
Arm swimming in the octopus is a mode of locomotion that is used by the animal primarily for hunting, defence, or escape. The motion, in general, is characterized by a fast closing of the arms and a slow opening of the arms, resulting in a considerable propulsive power. The movement has previously been discussed, however the detailed kinematics is still unknown. For that, we investigated in det...
متن کاملError Analysis of Stereo Calibration and Reconstruction
This paper addresses the problem of the propagation of input data errors in the stereovision process and its influence on the quality of reconstructed 3D points. We consider only those particular camera calibration and 3D reconstruction algorithms which employ singular value decomposition (SVD) methods. Using the SVD Jacobian estimation method developed by Papadopoulo and Lourakis, we determine...
