碩士 === 國立東華大學 === 資訊工程學系 === 91 === The objective of this thesis is to construct object movie with moving objects. In past researches, in order to allow the viewer to observe an object from any angle in a film, one had to utilize some expansive equipments in a special designed room. This thesis proposes to achieve the same goal with off-the-shelves equipments. The proposed method can be divided into two steps: the preprocessing and interpolation. In preprocessing step, first we capture image sequences from many different view angles, and store them with time relation in a special format called Multi-View Video. Then we extract feature points using SUSAN corner detection in each image, and design corresponding points algorithm to locate the corresponding feature points between each image pairs. Finally we use Delaunay Triangulation to produce a triangle mesh that is stored in an information file. In interpolation step, we use two files made in preprocessing (Multi-View Video and information file) and a technology similar to View Morphing to produce a virtual image sequence for an arbitrary viewpoint and view angle on real-time. In most traditional morphing methods, one creates virtual-viewpoint images by specifying reference points or reference lines manually. In our proposed method, however, virtual image sequence can be created automatically between any two existing image sequences.
