Il:\grs\Interwoven\NRPortbl\DCC\GRS\14056583_ .docx-27 04/2017 Device and method for optical quality control of the coating or staining of a kernel type substrate Abstract The invention relates to a device and a method for optical quality control of the coating or staining of a kemel-type substrate, in particular seed with a colour and contrast intensive coating composition. The device comprises a portable video unit comprising a colour video camera (2) and an opaquely sealed housing (1) for attaching the camera and illumination means, as well as an image analysis unit (not shown), which is connected to the video unit and in which a computer program is installed for colour distribution analysis of the colour image recording. The method provides the analysis of a colour image of a substrate sample consisting of a plurality of closely packed kernels for colour distribution on individual kernels.
