Method and machine for harvesting crop material

摘要

The invention relates to a method and apparatus for harvesting crop material, involving the determination of the proportion of a product in a mixture of products containing crop material and bodies foreign to the crop, comprising: the capture of at least one initial image of a surface of the mixture to be examined; the assignment to each image pixel of one of two extreme grey levels according to the initial grey level of the pixel relative to a set threshold; and the recording the number of pixels of at least one extreme grey level to determine a area ratio between areas occupied by fruit and foreign bodies in the image. The invention has particular application to the harvesting of fruit, berries and the like produced on trees or bushes grown in rows to use the calculated proportion to adapt at least one of the functioning parameters of the machine.
