碩士 / 國立中正大學 / 資訊工程研究所 / 102 / We present an interactive guidance and navigation system that assists users in acquiring pictures for image based 3D modeling. To reconstruct an object’s 3D model, users follow our instruction to take a set of images for an object in different angles; we therefore calculate their relative viewing positions and spare point cloud data using structure from motion technique. After we obtain sufficient number of images, we use Patch-based Multi-View Stereo (PMVS)[1] software to generate dense point cloud data. When displaying dense point cloud, we provide user an interface to eliminate those noise data points yielded from background construction or re-projection errors. Afterwards we reconstruct surface mesh as output. Our system provides informative message for failure while calculating camera poses and helps user how to resolve those problems. Furthermore, we assess the quality of camera poses reconstruction and generated point cloud to reveal the lack of angles for captured images and guides user to remedy those information.
