Method for the three-dimensional measurement of fast-moving objects

Abstract

Light sectioning or fringe projection methods are used to measure the surface of objects (2). According to said methods, the object (2) is moved past a measuring system (4) and the measured data is recorded during this movement. These methods can only be used for a high-resolution, comprehensive measurement of the surface if the object (2) is moved sufficiently slowly, in relation to the scanning rate of the measuring system (4), past said measuring system (4). To achieve a comprehensive measurement of the object surface, even when the object (2) performs a relatively fast movement, in particular a rotational movement, the object (2) is repeatedly moved past the measuring system (4) and measured. The use of a trigger device for recording the measured values permits the data obtained in the individual passes to be correlated in a three-dimensionally correct manner in relation to one another and the surface of the object to be measured with high resolution.
