Surface crack size determining method, e.g. for building, involves determining crack edges and determining crack size based on adjustment amount of crack edges up to covering and reproduction scale

The method involves exposing a charge-coupled device (CCD) array (2) with a known reproduction scale using an optical system. A surface (10) of an object (11) is illuminated with two light sources (3, 4) whose rays fall in a fixed angular field on the surface. Crack edges are determined and are brou...

description The method involves exposing a charge-coupled device (CCD) array (2) with a known reproduction scale using an optical system. A surface (10) of an object (11) is illuminated with two light sources (3, 4) whose rays fall in a fixed angular field on the surface. Crack edges are determined and are brought on top of each other for covering. Crack size is determined based on adjustment amount of the crack edges up to covering and the reproduction scale. Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Bestimmung einer Rissgröße in einem Objekt (11), bei denen über mehrere Lichtquellen (3, 4) ein Riss (6) unter einem definierten Einfallswinkelbereich beleuchtet und die Rissgröße anhand des Abbildungsmaßstabes und der Pixelanzahl eines CCD-Arrays (2) eines optischen Sensors ermittelt wird.
