Three dimensional movable object surface optical detection method, involves separating brightness distributions for different wavelengths by lens e.g. dichroic beam splitter, where distributions are detected by object surface

摘要

The method involves illuminating a surface (2) to be detected and/or illuminated of an object (1) by an illuminating arrangement (L) that is provided with four lights (L1-L4) i.e. blue high-power LEDs. Images of the object surface are taken by high-resolution interline cameras (K1, K2). Brightness distributions for different wavelengths (lambda 1, lambda 2) are separated by a lens e.g. dichroic beam splitter (ST) or evaluation electronics, where the brightness distributions are detected by the object surface to be detected. An independent claim is also included for a device for three dimensional optical detection of a surface of a three dimensional movable object.
