In a method having a device for individual grain sorting of objects (3.1) from bulk materials (3) on a conveying device (1) and an actuable discharge unit (2) which separates into fractions, the height distribution of the object (3.1) and the propagation of a light source (4) are advantageously used as sorting criterion, wherein a light-band (4.1) is projected transversely with respect to a conveying direction of the bulk material (3) on a plane of the conveying device (1), the objects (3.1) are moved through under the light-band (4.1), a first part (4.1.1) of the light is reflected, a second part (4.1.2) enters again at an entry point (3.1.1), is scattered and exits again at an exit point (3.1.2), a scattered propagation (B) is detected by a camera (9), and contiguous regions are identified in buffered rows (B |
