摘要： In a mark detecting system using an image pickup device such as a TV camera in which a mark in the form of a regressive reflector is provided on an object, the field of view of the image pickup device is illuminated with light of a specified wavelength from an illuminating device placed in the vicinity of the image pickup device. The reflected light is introduced on the image pickup device through a filter capable of cutting off light having wavelengths other than the specified wavelength. Since the mark forms a bright pattern on an image produced within the field of view of the image pickup device, the position of the mark can be easily detected by means of a data processor which processes image signals.
