Abstract: A system for locating at least one object in a real space by image processing, comprises a computation center (center), with a database of a virtual environment, a virtual representation of the real space, and computing the position of a point from which the virtual environment appears on a real space image obtained by an image acquisition device borne by the object. The center is sited remotely from the object. A data transmission device transfers the image data from the object to the center and the location data from the center to the object. The center processes the image data to determine a position from which the image was acquired, and stores, in a complementary database, data of the processed image to complement and/or to correct an initial database. The locating system implements a locating method for locating and transmitting the location data to a plurality of real environment objects.

Abstract: 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.

Abstract: 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.

Abstract: A method for generating a digital mockup in three dimensions using computer-aided design (CAD) software. The digital mockup is integrated into a spatialization environment for the digital mockup allowing visualization of the digital mockup from various angles of view. The digital mockup is produced to obtain a semi-finished product. A plurality of pieces of production information is acquired. For each piece of production information, a spatial position linked to the production information is measured, and the production information is integrated into the spatialization environment on the digital mockup at a position in the digital mockup corresponding to the measured spatial position.

Abstract: The invention relates to an attribute selection method for making statistical learning of descriptors intended to enable automatic recognition and/or detection of an object from a set of images, method characterized by the following steps: obtain a mask of the object in each image containing said object to be recognized, define and select at least one set of descriptors as a function of their geometric shape and/or apparent specific physical characteristics, calculate attributes associated with this shape and said specific physical characteristics, sort the descriptors as a function of their respective scores, select descriptors with the highest scores to perform said statistical learning.
