Many vision and augmented reality applications require knowing the rotation of the camera relative to an object or scene. In this paper we propose to create a structured light field designed explicitly to simplify the estimation of camera rotation. The light field is created using a lenticular sheet with a color coded backplane pattern, creating a lightfield where the observed color depends on the...
A method of detecting projected circle centers (PCC) based on array circles is proposed. The perspective distortion of projected circle centers could be eliminated from coplanar circles. By utilizing the property of projected coplanar circles, lines connecting PCCs are computed from projective invariant points defined by the projected circles (PCs), and then the PCCs are determined from the intersection...
