Abstract

The present invention relates to a method and a device for contactless scanning of an object (1). Light is conducted by distributing means (11, 12, 13) to the object and neighbouring surfaces (2, 16). A detecting means (9) detects light which is reflected by the object and the surfaces. The reflectivity of the surfaces is excellent, and the detecting means receives reflected light of high intensity from the surfaces. Light hitting the edge portion of the object will be spread when reflected, which implies that the detecting means receives light of low intensity. Consequently, the intensity will be high for the surfaces but will be at its lowest at the contour of the object. Therefore, signals depending on the detected intensity can be processed in a computer. The computer calculates a reproduction of the object, which can be used for e.g. calculating the length, width, height or volume of the object.
