Abstract

In this paper, we suggested a new way to overcome a shortcoming as stereoscopic depth distortion in common stereoscopy based on computer graphics (CG). In terms of the way, let the objective space transform as the distorted space to make a correct perceived depth sense as if we are seeing the scaled object volume which is well adjusted to user's stereoscopic circumstance. All parameters which related the distortion such as a focal length, an inter-camera distance, an inner angle between camera's axes, a size of display, a viewing distance and an eye distance can be altered to the amount of inversed distortion in the transformed objective space by the linear relationship between the reconstructed image space and the objective space. Actually, the depth distortion is removed after image reconstruction process with a distorted objective space. We prepared a stereo image having a right scaled depth from -200mm to +200mm with an interval as 100mm by the display plane in an official stereoscopic circumstance and showed it to 5 subjects. All subjects recognized and indicated the designed depths.
