多視点裸眼立体視ディスプレイLuminantCubeのキャリブレーション手法

Abstract

The 3D display using light diffusion within 3-dimensionally positioned micro voids processed in a crystal glass cuboid is able to present 3D objects which can beobserved by naked eye. In order to successfully present 3D objects, the projection mustbe adjusted precisely for each individual micro void by investigating the correspondencebetween each projector pixel and micro voids. In this research, hence, calibration methods which can perform such adjustment automatically were developed, namely; PixelScan Method, Line-Scan Method and Structured-Light Method. Line-Scan Method andStructured-Light Method were developed in aim of shortening the processing time of thecalibration. Subjective experiment was conducted in order to evaluate the calibrationmethods. The results show that Structured-Light Method is faster in processing timebut degraded in quality for the presented images. However, despite Line-Scan Methodbeing faster than Pixel-Scan Method, the degradation of the presented images was minor.
