Claim 14:
15. A method for detecting a workpiece, comprising:
providing the detection device of claim 1;
placing the workpiece on the rotary table and rotating the rotary table so that the workpiece passes through the plurality of photographing devices in turn;
capturing images of the side surfaces of the workpiece by the image capture devices of the plurality of photographing devices; and
recording the first offset angle and the second offset angle while the image capture device captures the image of the corresponding side surface,
wherein, when the workpiece is a cuboid, the method further comprises calculating the 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.
