Abstract: The invention relates to a network of switched optical fiber for airplane seats. The network connects the screens of the seats to each other and to a server via an optical fiber. The network includes optical switches of the MEMS type including mirrors, said switches being provided perpendicular to each seat. Each switch delivers the light beam in the optical fiber to the screen with which it is connected and re-amplifies it in the optical fiber when it is powered, while the switch directly delivers the light beam to the following seat when it is not powered.

Abstract: The invention relates to a method for the automatic calibration of a stereovision system which is intended to be disposed on board a motor vehicle. The inventive method comprises the following steps consisting in: acquiring (610) a left image and a right image of the same scene comprising at least one traffic lane for the vehicle, using a first and second acquisition device; searching (620) the left image and right image for at least two vanishing lines corresponding to two essentially-parallel straight lines of the lane; upon detection of said at least two vanishing lines, determining (640) the co-ordinates of the point of intersection of said at least two respectively-detected vanishing lines for the left image and the right image; and determining (650) the pitch error and the yaw error in the form of the intercamera difference in terms of pitch angle and yaw angle from the co-ordinates of the points of intersection determined for the left image and the right image.
