摘要： A method of 3D reconstruction of a scene, including the implementation of at least two sensors each having a series of elementary receivers arranged so as to view the scene according to distinct respective solid angles and which are each sensitive to a physical characteristic of a signal received by the receiver originating from the scene. The sensors are adapted for emitting an asynchronous stream of events indicative of a modification of the signal received by one of the elementary receivers at a given instant, as well as the implementation of a 3D reconstruction algorithm having a step of pairing elementary receivers of each of the sensors utilizing signals generated by the sensors, the pairing including pairing between them events generated by each of the sensors and temporarily close together.

摘要： Methods for calibrating at least two video cameras for a stereoscopic device includes: providing, on the lane portion, nine marks of hue other than that of the lane, sequenced on a first set of three concurrent virtual straight lines in a first point and distributed in specific manner on a second set of concurrent virtual straight lines in a second point; forming, with each of the cameras an image of the lane portion; defining, in each of the two images, one characteristic point of each mark image; determining, with the characteristic points, six concurrent straight line images respectively in two concurrent points; and processing the video signals delivered by each video camera such that the signals are representative of two images suitable for forming a stereoscopic video image. The method is useful for determining the occupancy condition of a lane portion and detecting incidents.

摘要： An input signal (f) representative of a scene to be viewed comprises, for each pixel of a matrix of pixels, an event-based asynchronous-signal sequence obtained as a function of variations of light relating to the pixel in the scene. This input signal is transformed spatially within the matrix of pixels and temporally along the signal sequences to generate respective control signals (S) for pixel zones of a device for aiding vision (20).
