Abstract

In this paper, we analyze the distortion of images acquired with a novel Ray-Space acquisition system. In case an arbitrary viewpoint picture is generated using the Ray-Space method, it is necessary to acquire dense ray data. Conventional methods for acquiring the Ray-Space data consist of using rotating stages or a camera array. We developed a system consisting of two parabolic mirrors, a synchronized galvanometric mirror and a high-speed camera. The principle is as follows; if an object is put in the bottom of the parabolic mirror, the ray which comes out of the object is imaged in the upper part, and form a real image. The galvanometer mirror is put on the position of a real image, and is made to scan horizontally. Images of the object of different angles (directions) are then possible to generate and are captured by the high-speed camera. By capturing many images at each scan, Ray-Space is therefore acquirable. However, distortion arises in the real image of the object formed. Consequently, distortion appears in the captured image. Therefore, it is necessary to correct the captured image to the right image. Here, we examine a method to generate corrected images from the acquired Ray-Space.
