Rotating line cameras: Epipolar geometry and spatial sampling

Abstract

Abstract. Rotating line cameras project 3D scenes on a cylindric surface, where one or multiple rotating sensor lines allow to compose panoramic images line by line. An important special case of such a camera is defined by two lines with symmetric viewing angles with respect to the cylinder’s surface normal. The report analyzes epipolar geometry for the general case of such rotating line cameras, and discusses spatial distributions of (potential) 3D samples for the special symmetric camera architecture.
