A 3D model reconstruction workflow with hand-held cameras is developed. The exterior and interior orientation models combined with the state-of-the-art structure from motion and multi-view stereo techniques are applied to extract dense point cloud and reconstruct 3D model from digital images. An overview of the presented 3D model reconstruction methods is(More)
AIM The objective of this study was to investigate the influence of OSA on cardiac function in Chinese patients with ST-elevation myocardial infarction (STEMI) and determine the prognostic impact of OSA among these patients. METHODS In this retrospective study, 198 STEMI patients were enrolled. Doppler echocardiography was performed to detect the effect(More)
Spatial topology rule is the primary method to insure the consistency and validity of spatial topol-ogy relation in GIS software. Topology rule can be divided into three categories according to geographic en-tity's geometric shape: point topology rule, line topology rule and polygon topology rule. At first, this paper summarizes the various linear(More)
