摘要： The invention relates to a shot-processing device which comprises a memory (10), a detector (20), a preparer (30), a combiner (40), an estimator (50) and a selector (60). The memory (10) is arranged to receive, on the one hand, scene data (12) that comprise three-dimensional object pairs each associating an object identifier, and ellipsoid data which define an ellipsoid and its orientation and a position of its centre in a common frame of reference and, on the other hand, shot data (14) defining a two-dimensional image of the scene associated with the scene data (12), from a viewpoint corresponding to a desired pose. The detector (20) is arranged to receive shot data (14) and to return one or more two-dimensional object pairs (22) each comprising an object identifier present in the scene data, and a shot region associated with this object identifier. The preparer (30) is arranged to determine, for at least some of the two-dimensional object pairs (22) from the detector (20), a set of positioning elements (32) whose number is less than or equal to the number of three-dimensional object pairs in the scene data (12) that comprise the object identifier of the two-dimensional object pair (22) in question, each positioning element (32) associating the object identifier and the ellipsoid data of a three-dimensional object pair comprising this object identifier, and ellipse data which define an ellipse approximating the shot region of the two-dimensional object pair in question and its orientation as well as a position of its centre in the two-dimensional image. The combiner (40) is arranged to generate a list of candidates (42) each associating one or more positioning elements (32) and a shot orientation, and/or the combination of at least two positioning elements (32), the positioning elements (32) of a single candidate (42) being taken from separate two-dimensional object pairs (22) and not relating to the same three-dimensional object pair. The estimator (50) is arranged to calculate, for at least one of the candidates, a pose (52) comprising a position and an orientation in the common frame of reference from the ellipse data and the ellipsoid data of the positioning elements, or from the ellipse data and the ellipsoid data of the one or more positioning elements and the shot orientation. The selector (60) is arranged, for at least some of the poses, to project all of the ellipsoid data of the scene data onto the shot data from the pose, to determine a measurement of similarity between each projection of the ellipsoid data and each ellipse defined by a two-dimensional object pair (22) coming from the detector (20), and to calculate a likelihood value by using, for each projection of the ellipsoid data, the largest measurement of similarity determined, and to select the pose that has the highest likelihood value.

摘要： A locating device comprises a memory (10) arranged to receive data concerning the distance between a plurality of anchors and one or more mobile sources at a plurality of locations different to each other. The number of anchors and the number of locations is such that one must be higher than four and is designated as the primary number, and the other higher than ten and is designated as the secondary number. The device further comprises a decomposer (4) arranged to calculate a decomposition, into singular values, of a matrix formed by the product of the Euclidean distance matrix derived from the distance data multiplied by two square matrices, one of which has a size equal to the primary number squared and the other is the transpose of a matrix with a size equal to the secondary number squared. The device further comprises a reducer (6) arranged to calculate a resolution vector minimising, according to the least squares method, the difference between the product of a simplification matrix multiplied by the resolution vector and a matrix formed by the product of the Euclidean distance matrix derived from the distance data multiplied by a vector of which all the elements are equal to one except the first element which is zero, and by a vector of which all the elements are zero except the first which is equal to one, and a solver (8) arranged to derive an inversion vector from the last three elements of the resolution vector and an inversion matrix formed from the other elements, in order to determine a transformation matrix such that the inversion matrix is equal to the product of the transformation matrix multiplied by its transpose, and to return a matrix of coordinates of the anchors and a matrix of coordinates of the locations from the transformation matrix, the inversion vector, the first matrix of the decomposition into singular values and the product of the second matrix and the third matrix of the decomposition into singular values.

摘要： Disclosed is a method for diagnosis by reflectometry of a bundle of power lines including an input point and a plurality of branches, including the following steps: inserting (S50) electric markers having different frequency characteristics onto the branches of the bundle; injecting (S52) a test signal into the bundle from the input point; receiving (S54) a set of reflected signals produced by reflections of the test signal in the branches; analyzing all the reflected signals by identifying the markers and by assigning (S56) each reflected signal to one of the branches according to the frequency characteristic of the marker inserted onto the branch; and identifying the presence/absence of a defect in the branch by comparing (S58) the reflected signal assigned to the branch with a reflected signal model obtained by modelling the reflection of the test signal in the branch in the absence of any defect in the branch.

摘要： At least one of the present embodiments generally relates to a method and an apparatus for sparse representations of signals by a computer. Representations are based on a set of known data, referred to as a dictionary. Sparse representations are achieved by selecting the items from the dictionary that are closest to the content to be compressed, and only transmitting information related to these selected items.
