PROBLEM TO BE SOLVED: To keep an imaging distance constant and also to appropriately perform the image processing of an imaged workpiece. SOLUTION: This system is provided with: an imaging device 87 for imaging the shape of the workpiece W bent with a die 33; a moving device 13 for moving the imaging device 87 in a prescribed direction and positioning it; a moving device controlling means for controlling the moving device 13; and optical reflecting member 91 for reflecting the image of the workpiece W in the direction of the iimaging device 87 by a prescribed angle. By performing control for moving the imaging device 87 in accordance with a position where the workpiece W is installed, a distance from the workpiece W to the optical reflecting member 91 and a distance from the optical reflecting member 91 to the iimaging device 87 are kept constant. Meanwhile, by preliminarily storing the image of a reference flange, picking up the image of a flange after bending the workpiece W and confronting the picked-up image of the flange with the image of the reference flange, the angle between the image of the reference flange and that of the picked-up flange is determined on the basis of confrontation.
