2板式カメラによる農作物の認識

A TV camera with two image sensors was made by trial to recoginze the agri cultural crop and was tested． This camera consisted of two monochrome TV cameras，a lens and a spectroscopic optical device. Each monochrome camera had a MOS type image sensor and was synchronized each other by an external synchronizing signal. Two images of different wavelength formed on these image sensors and their video signals were compared by a dividing circuit to recognize the agricultural crop. The output signal of the dividing circuit was fed to a computer and the crop image was obtained.
