A rapid succession of objects such as sweets are sorted according to shape by being fed through a viewing zone, flash illuminated in the viewing zone, and viewed by a number of fixed electronic viewers spaced in one plane around the viewing zone through just under 180 DEG , the edges of the images produced by the viewers being examined for approximation to a spherical shape, approximation to symmetry and reentrants, and one of a number of air jet nozzles being thereby automatically energised to direct the object into an appropriate bin. |
