Claim 19:
20. The detection device of claim 16, wherein:
the plurality of photographing devices are adapted to capture images of corresponding ones of the side surfaces of the workpiece; and
the detection device is adapted to record the first offset angle and the second offset angle while the plurality of photographing devices capture the images of the corresponding side surfaces, wherein, when the workpiece is a cuboid, the detection device is further adapted to calculate a size of the corresponding side surface by the following formulas:

E1=e1/cos α1

wherein E1 is the length of one edge of the corresponding side surface, and e1 is the length of the image of the one edge, α1 is the first offset angle; and

E2=e2/cos α2

wherein E2 is the length of the other edge adjacent to the one edge of the corresponding side surface, and e2 is the length of the image of the other edge, α2 is the second offset angle.
