Apparatus and method for testing and spatial measurements of rotating objects, and in particular of tires

Device for testing and spatial measurements of rotating objects, in particular tires (14), with generates an image capture device (21) which captures an image (V) of the object to be measured (14) and a frame signal (VD); a zero position detector (50) in accordance an object-side reference position (51a) having an apparatus-side reference position (51b) is a zero position signal (RI) generated; a signal processing device (40), the frame signal (VD) and the zero position signal (RI) to an offset signal (RI wherein the offset signal (RI
