Abstract
A system and method are disclosed for highly efficient imaging of selected object features utilizing, in combination, a 2D imaging subsystem and a 3D imaging subsystem wherein data from the 2D imaging subsystem is used to predetermine areas containing 3D features of interest such that delay attributable to imaging of areas of non-interest for 3D features is minimized.
Claims19
A method for imaging an object, comprising the steps of:
- scanning a selected region of the surface of an object with a 2D optical detector to obtain data corresponding to 2D features of the selected region of the surface;
- generating a 2D image from the data corresponding to 2D features of the selected region of the surface;
- scanning the selected region of the surface of an object with a 3D optical detector to obtain data corresponding to 3D features of the selected region of the surface;
- and
- generating a 3D image of portions of the selected region of the surface, the portions of the selected region being selected based upon the 2D image previously generated for the selected region.
