A method for projecting information issued from a digital design model. Calibration is performed by acquiring characteristic data originating from a surface of interest and comparing the characteristic data with virtual data issued from the digital design model. A spatial position of a projecting device is determined. The projecting device comprises a video projector and at least two separate image-capturing devices. Depending on the spatial position, information issued from the digital design model is projected by the video projector onto the surface of interest.

Method for projecting virtual data and device enabling this projection

A method for processing local information acquired by a virtual representation and a device having an inertial unit and an image sensor. At least one image of a real environment of the device is captured. The localization of the device in the virtual representation, corresponding to the localization of the device in the real environment, is obtained by correlating the portions of the captured image and portions of the virtual representation, The inertial unit determines the displacement of the device. The localization of the device in the virtual representation is modified as a function of the displacement so that the real position of the device corresponds, during the displacement, to the localization of the device in the virtual representation.

Method for processing local information

A method of searching for a scene based on a stream of images archived in a video surveillance database including: a first phase of preprocessing prior to archiving of the images including extracting generic information from the images of the stream, systematically annotating the scenes of the images by at least one indication defined as a function of the generic information, and indexing the scenes of the images based on information extracted from the indications originating from one or more streams; a second phase of investigation by preselecting video segments from the stream of images including the annotation indications associated with the images; and a third phase of searching for a particular scene based on at least one additional characteristic not forming part of the annotations associated with the preselected video segments.

Method of optimizing the search for a scene on the basis of a stream of images archived in a video database

The invention relates to a method for virtually expanding and enriching the field of view of the current image of a scene described by a video including several images. This method includes the following steps of:
