Thanks to the advances of data acquisition techniques, we can acquire ventricular blood flow data with very high quality. This extremely complex spatiotemporal data calls for novel visualization and analysis tools. In particular, the new tools need to assist domain experts in quick identification of critical patterns. In this paper, we present a method using topo-logical data analysis tools with simulated...
3D point cloud is the original format of three dimensional map for the navigation of mobile robotics. Time of Fight camera can directly return 3D points and grayscale image simultaneously, but the color information is lost. In this paper, 3D points are colored by calibrating PMD camera with RGB camera, and then the RGB image is generated with respect to a frame of TOF camera. Point cloud form only...
In this paper, the feasibility of building seismic damage assessment using oblique images is discussed. Firstly, some geometric features of buildings are selected and analyzed according to the universal geometric characteristics of most buildings. Secondly, the parameters of each geometric features are calculated by the method of photogrammetry. Finally, the results of parameters calculation are analyzed...
