Close Range Photogrammetry 3D sensors Computer Vision Adjustment
2015/12/4
In recent years real time active 3D range cameras based on time-of-flight technology using the Photonic-Mixer-Device (PMD) havebeen developed. Those cameras produce sequences of low-resolution d...
Analysis of the motion behaviour of Jacobshaven isbræ glacier in Greenland by monocular image sequence analysis
Motion analysis image sequences glaciology
2015/8/24
Jakobshavn Isbræ on the west coast of Greenland is one of the fastest and most productive glaciers in the world. It has been moving with an average velocity of 20 meters per day over a long time,...
ROBUST METRIC STRUCTURE FROM MOTION FOR AN EXTENDED SEQUENCE WITH OUTLIERS AND MISSING DATA
structure from motion robust estimation projective reconstruction metric upgrade
2015/8/14
In this paper, we propose a robust metric structure from motion (SfM) algorithm for an extended sequence with outliers and missing
data. There are three main contributions in the proposed SfM algorit...
