Claim 15:
16. 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 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 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, the plurality of photographing devices including:
a first side surface photographing device located at an outer side of the rotary table and arranged higher than the workpiece in a direction perpendicular to the rotary table, the first side surface photographing device capturing an image of a first side surface of the workpiece when the workpiece is rotated to the first side surface photographing device;
a second side surface photographing device located at an inner side of the rotary table and arranged higher than the workpiece in a direction perpendicular to the rotary table, the second side surface photographing device capturing an image of a second side surface of the workpiece facing a center of the rotary table when the workpiece is moved to the second side surface photographing device;
a third side surface photographing device located at the outer side of the rotary table and arranged higher than the workpiece in the direction perpendicular to the rotary table, the third side surface photographing device capturing an image of a third side surface of the workpiece away from a center of the rotary table when the workpiece is moved to the third side surface photographing device, the second side surface and the third side surface are opposite to each other in a radial direction of the rotary table; and
a fourth side surface photographing device located at the outer side of the rotary table and arranged higher than the workpiece in the direction perpendicular to the rotary table, the fourth side surface photographing device capturing an image of a fourth side surface of the workpiece when the workpiece is moved to the fourth side surface photographing device, first side surface and the fourth side surface are opposite to each other in a rotation direction of the rotary table.
