This paper describes the development of an original stereoscopic sensor suitable for cylindrical and spherical 3D imaging. Its principle is based on the rotation of two linear CCD cameras with their optical center on the rotation axis of a stepper motor. The architecture of the sensor allows us to obtain panoramic images with a cylindrical geometry. By adding a second rotation axis orthogonal to the first rotation axis, color stereoscopic spherical images are obtained. This second axis gets through the middle of the two cameras. Due to the geometrical precision acquisition of the color pixels and the faithful restitution of the colors, high quality color images are obtained. The concept of this sensor simplifies calibration and feature matching by reducing classical 2D matching problem to 1D. This original sensor is dedicated to real scenes acquisition for multimedia and motion pictures applications over 360 X 360 degrees.
