環場全景製作技術及其在虛擬實境應用

Abstract

The primary objective of this thesis is to explore the panoramic view generation. The user chooses a suitable viewpoint in real environment in advance, sets up the camera on a tripod , and then takes a number of (usually 24) images of the scene around the camera. Through some procedures of image processing such as the tilted image correction, image warping, image stitching, and image blending, we can warp these 24 images into a cylinder. We hope to provide an automatic procedure for the panoramic view generation.In case the user holds the camera with hands when taking the images, there might be some additional problems caused by camera pan, tilt andpitch. Under such circumstances, we can also correct these images by means of 2D projective transformation with the aid of the manually selected correspondence points. At the end, we can still make a panoramic view. We also do some virtual reality applications using the panoramic viewand combine the panoramic view with graphics- based 3D object models.
