以立體視覺方式改進三維物體剪影重建法

An Improvement on the Silhouette-based 3D Object Reconstruction by Stereo Vision

指導教授 : 林祺政
共同指導教授 : 李道明(Daw-Ming Lee)

摘要


本文提供一個描繪真實物體三維模型(3D model)的方法,利用從不同方向拍攝物體所獲得的二維影像重建三維模型。本文利用多面鏡的反射來一次獲取多方向的二維影像,並且使用立體視覺(stereo vision)方法來改進剪影法(silhouette-based)運用在多面鏡時產生的問題,達到操作簡單和使用者容易接受的目的。多面鏡為許多環繞在物體周圍的平面鏡所組成,因此可以同時看到許多不同視角的影像。本文便是利用此一方式來簡化拍攝影像的步驟,有效縮短使用者再擷取影像上的時間。本文方法的優點為方便與經濟,可以作為3D動畫師快速的輔助工具或是提供一般使用者將物體數位化的工具。

This paper provides a solution to reconstruct 3D model from an object by getting 2D images from different directions. The method getting 2D images is using multi-mirror device at the same times. By using the stereo vision solution solves the problem of using silhouette- based on the multi-mirror, and it becomes acceptant and bare-bones. A multi-mirror device is composed of several planar mirrors around the object, so we can see some multi-image at the same time. Using multi-mirror device saves a lot of time on capturing images. This paper provides the advantage of convenience and cheapness, and it proves to be a tool for 3D animation designer or common user.
