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 and measurement pixels of an object in the image, wherein the measurement pixels are converted into an approximation of coordinates of positions to be measured assuming a default distance to the positions, and the optical axis of the lens arrangement is adjusted sequentially onto the positions to be measured. After measuring the distances to the positions, the coordinates are recalculated increasing the accuracy of the coordinates.
