A NOVEL PROJECTION ALGORITHM FOR PRODUCTION LAYOUT EXTRACTION FROM POINT CLOUDS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
The paper is focused on point cloud data processing obtained by 3D laser scanning. The scanning devices are at a very advanced level and after reaching their possible maximum scanning speeds, manufacturers are now more ...
OPTIMIZATION OF COMPUTATIONAL BURDEN OF THE POINT INFORMATION GAIN
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
We developed a method of image preprocessing based on the information entropy, namely, on the information contribution made by each individual pixel to the whole image or to image’s part (i.e., a Point Information Gain; ...
APPLICABILITY VERIFICATION OF AUTOFORM SOFTWARE FOR FEM SIMULATION OF MECHANICAL FIXATION OF HEMMED JOINTS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
This paper deals with the problematics of fixation of hemmed joints, especially with one specific mechanical method how to ensure a dimensional stability of a hemmed joint of car-body parts, such as doors, bonnet and trunk ...
THE INFLUENCE OF BASALT MINERALS AS CEMENT SUBSTITUTION MATERIALS IN MORTAR
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)
This study was conducted to determine the effect of the concentration of basalt as a cement substitution material in mortar. Basalt was analysed by XRD and XRF. From the XRD results, the diffractogram shows the dominant ...
