#$%^&*AU2015205898B220160331.pdf#####Abstract Disclosed is 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 accommodating an array of sensor elements, - means for generating a probe light incorporating a spatial pattern, - means for transmitting the probe light towards the object thereby illuminating at least a part of the object with said pattern in one or more configurations, - means for transmitting at least a part of the light returned from the object to the camera, - means for varying the position of the focus plane of the pattern on the object while maintaining a fixed spatial relation of the scanner and the object, - means for obtaining at least one image from said array of sensor elements, - means for evaluating a correlation measure at each focus plane position between at least one image pixel and a weight function, where the weight function is determined based on information of the configuration of the spatial pattern - data processing means for: a) determining by analysis of the correlation measure the in-focus position(s) of: - each of a plurality of image pixels for a range of focus plane positions, or - each of a plurality of groups of image pixels for a range of focus plane positions, and b) transforming in-focus data into 3D real world coordinates.WO 2010/145669 PCT/DK2010/050148 I 0 0 0 I I- - - r I 0 I L _ _ _ _ _ _ _ _ _ _ _ _ _ A0 000
