Claim 0:
1. A detection device for detecting a workpiece with multiple surfaces, comprising:
a rotary table carrying the workpiece and moving the workpiece by rotation; and
a plurality of photographing devices arranged at a plurality of different positions around the rotary table, each photographing device has an image capture device capturing an image of a corresponding surface of the workpiece that is moved to the image capture device, an orientation of the image capture device is defined by a first offset angle and a second offset angle when the image capture device captures the image of the corresponding surface of the workpiece, the first offset angle is an angle of no less than 0 degrees and no larger than 30 degrees between a normal direction of the corresponding surface and an orthographic projection of an optical axis of the image capture device on a plane perpendicular to a rotation axis of the rotary table, the second offset angle is an angle of no less than 0 degrees and no larger than 30 degrees between the normal direction of the corresponding surface and an orthographic projection of the optical axis of the image capture device on a plane parallel to the rotation axis of the rotary table and perpendicular to the corresponding surface.
