摘要:
A scanner for obtaining and / or measuring the 3D geometry of at least a part of the surface of an object, said scanner comprising: - at least one camera (180) containing an array of sensor elements, - a means to generate (110, 120, 130) a probing light that incorporates a spatial pattern, - a means to transmit (140, 150, 170) the probing light towards the object, thereby illuminating at least a part of the object with the said pattern in one or more configurations, - a means for transmitting (140, 150, 170) at least a part of the light returned from the object to the camera (180), - a means for varying (151) the position of the plane of focus of the pattern on the object while maintaining a fixed spatial relationship between the scanner and the object, - a means to obtain at least one image of said matrix of sensor elements, - a means to evaluate a measure of the correlation in each position of the focus plane between at least one image pixel and a weighting function, in which the weighting function is determined based on the spatial pattern configuration information; and - a means of data processing to: a) determine by position correlation analysis the position or focus positions of: - each of the plurality of image pixels for a range of focus positions, or - each one of the plurality of groups of image pixels for a range of focus plane positions, and b) transform the focused data into 3D real world coordinates.Un escáner para la obtención y/o la medida de la geometría 3D de al menos una parte de la superficie de un objeto, comprendiendo el citado escáner: - al menos una cámara (180) que contiene una matriz de elementos sensores, - un medio para generar (110, 120, 130) una luz de sondeo que incorpora un patrón espacial, - un medio para transmitir (140, 150, 170) la luz de sondeo hacia el objeto, iluminando por ello al menos una parte del objeto con el citado patrón en una o más configuraciones, - un medio para transmitir (140, 150, 170) al menos una parte de la lu
