Abstract

An optical instrument and a method for obtaining distance and image information of an object is disclosed to improve the speed and accuracy of data acquisition. The instrument comprises a camera, positioning unit, distance measuring unit, lens arrangement and control unit. The camera acquires images of an object and the control unit defines an area to be scanned as well as an object feature of the object, wherein measurement pixels corresponding to positions on the object may be defined in the area with an increased density of measurement pixels at the object feature. Subsequently, the distances to the object at the selected positions of interest are measured.
