Embodiment Construction
[0041] The invention discloses a method and device for rapid size measurement and defect detection of a ring-shaped workpiece. figure 1 It is a device detection flowchart of the present invention, as shown in the figure:
[0042] Step 1: After the system is started, the circular workpiece enters the rotating disc;
[0043] Step 2: The optical fiber sensor (1) monitors the rotating disc, and a trigger signal is generated when a workpiece passes through;
[0044] Step 3: The trigger signal is sent to the three imaging stations respectively, figure 2 It is a schematic diagram of the station layout device of the present invention, and each station device is shown as figure 2 shown.
[0045] Step 4: After the imaging station obtains the image, the original image is sent to the software platform, and the software platform uses different algorithm detection modules for detection according to the images of different stations. Its main detection principle is:
[0046] 1) Station...
