triangulation and texture mapping on the point cloud obtained by four-view matching. This method was tested on the 3D reconstruction of a terracotta soldier sculpture and the Buddhas in the Mogao Grottoes. Their point clouds without mismatched points were obtained and less processing time was consumed in most cases relative to binocular matching. These good reconstructed models show......

. The antisite formation energy of Pt in Fe sublattice is 0.09 eV. The tendency of the vacancy formation energy is in agreement with other calculation. The point defect structure types are Pt antisite in rich-Pt side and Fe antisite in rich-Fe side. Key words: intermetallics; FePt; point defects; molecular dynamics; embedded-atom method 1 Introduction FePt alloy of L10 ordered structure with large......
transformation temperature Tm and Curie point Tc are in linear relation to quenching temperature. Tm increases by 9 K and Tc increases by 7.5 K for every 10 K increasing in quenched temperature. Quenched from same temperature, Tm of Co41Ni32Al24Sb3 alloy is higher than that of Co41Ni32Al27 alloy by 76 K, meanwhile Tc is higher by 18 K. The melting point of Co-Ni-Al alloy is decreased by the Sb addition......
GmbH Germany,part of Springer Nature 2020 Abstract: This paper presents a voxel-based region growing method for automatic road surface extraction from mobile laser scanning point clouds... boundary using the curb-based segmentation algorithm. To evaluate the accuracy of the proposed method, the two-point cloud datasets of two typical test sites in an expressway environment consisting of flat......
℃ and 495 ℃, and the ordinary burnt phenomena of the ingots between 480 ℃ and 495 ℃ does not occur because the excess low-melting point eutectic phases in the as-cast alloy dissolve into the matrix during... point eutectic phases; overburnt temperature ......
