Stereoscopic filming is roughly divided into two types: toed-in and parallel camera configurations. Both types have
disadvantages: toed-in cameras cause keystone distortions, and parallel cameras cause image loss by shifting. In addition,
it is difficult for inexperienced creators to understand the optimal camera settings and post-processing procedures, such
as cross points and inter-camera distance, in both types. These factors hinder the creation of stereoscopic images.
Therefore, the authors focused on improving usability in stereoscopic filming, constructed an experimental camera
system, and examined semi-automatic camera configuration function in terms of viewing safety.
The purpose of the research project reported here is to create more life-like representations of cultural heritage items by
presenting stereoscopic images based on 3D data. In this paper, the authors report on the work of archiving heritage
items in China's National Palace Museum and on the development of an interactive stereoscopic viewer system. A
horizontal stereoscopic representation with interactivity is examined as a method of obtaining a "depth" sensation. The
aim is to represent cultural heritage from a low level close to that of the real environment, such as in a museum, and to
provide tactile sensation. The viewer system consists of a 3D display using Xpol, a touch panel, and a tilt encoder. the
system is controlled by a Windows PC with custom software. The touch panel works for not only general interactions,
such as moving the displayed 3D images, but also offers an unusual type of interaction known as "tracing". The tilt
encoder detects the angle of the display and rotates the 3D images accordingly. These interactions control the coordinates
and parallax of the 3D images in real time to provide an experience similar to holding the real object directly. In
addition, the authors examine the effectiveness of the viewer system through a subjective evaluation.
