Since few years, the gastroenterologic examinations could have been realized by wireless video capsules. Although the images make it possible to analyze some diseases, the diagnosis could be improved by the use of the 3D Imaging techniques implemented in the video capsule. The paper presented here is related to Cyclope, an embedded active vision system that is able to give in real time both 3D information and texture. The challenge is to realize this integrated sensor with constraints on size, consumption, and computational resources with inherent limitation of video capsule. In this paper, the authors present the hardware and software development of a wireless multispectral vision sensor which allows to transmit, a 3D reconstruction of a scene in realtime.
