摘要： The invention relates to an ultrasound imaging system for forming an echographic image of a medium, which system includes a set [REC] of transducer elements [EL] which are operative in a transmission mode and in a reception mode for ultrasound waves, construction means [REB] for constructing echographic signals on the basis of signals [S[1] ... S[N]] received on said transducer elements [EL], display means [DIS] which are coupled to said construction means [REB] in order to display an image of the medium formed by means of the echographic signals. Said construction means [REB] are such that in so-called exclusion zones, in which a coherent reflector is detected and which are determined by determination means [DET], the reception delays [D] are estimated in a manner [INT] other than that [CORR] used for the other zones. The calculation [CAL] of echographic signals is then carried out on the basis of said estimated delays [D[Z],Di[Z]]. The invention enables a correction of phase aberrations and nevertheless offers an excellent lateral resolution, notably in the case of point coherent reflectors.

摘要： A method of estimating the position of the field of view of an imaging device, such as a camera, relative to a board involves designating markings on the board as references and detecting the shift in these reference markings within the field of view of the camera compared to a known position therein. The reference markings are selected such that detection thereof involves analysis of only a subset of the image produced by the imaging device. The selection of a group of one or more markings to serve as a reference involves determination of the image region (error window) in which the reference marking(s) may appear, given the maximal positional error of the imaging device. It is also checked (step T4) that the entire error window will be within the useable field of view of the imaging device and that, within the error window, no other group of markings will appear that could be confused with the selected group of markings (step T5). Detection of the reference group of markings involves generation of an image profile along a line crossing the center of the error window and finding the best match between the markings along this profile and the markings in the reference group.

摘要： A method of estimating the position of the field of view of an imaging device, such as a camera, relative to a board involves designating groups of markings on the board as reference groups and detecting the respective shifts in a set of these reference groups within the field of view of the camera compared to known positions therein. . A choice is made between the various possible sets of unambiguously-identifiable reference groups to be used for position estimation. This choice is based on a genetic algorithm optimization process in which the individuals in the population are different sets of candidate reference groups, a plurality of generations of individuals is generated, and the individual having the highest measure of a fitness parameter is selected to provide the set of reference groups to be used in position estimation. Advantageously, detection and localization of the reference groups involves analysis of only respective subsets of the image produced by the imaging device.
