A METHOD AND DEVICE FOR RECORDING IMAGES OF GRAINS FROM CEREALS TO DETECT CRACKING

摘要

A method and device for recording images of small particles to analyze the quality of the particles, especially to detect any cracking in the particles. The method comprises the steps of feeding (102) particle samples which each comprise at least one particle, to a place for image recording, and illuminating (104) a particle sample from at least two directions simultaneously, the illumination occurring with different light wavelengths for each direction. The method further comprises the steps of recording (106) an image of the illuminated particle sample with the aid of an image-recording means, which records partial images of the particle sample in different channels, which are sensitive to different wavelengths, and comprising (108) the different partial images to analyze the particle sample. Each partial image shows the particle sample illuminated from one direction by the channel recording only one of the different light wavelengths.
