Embodiment Construction
[0035] The present invention will be further described below in conjunction with the accompanying drawings.
[0036] refer to Figure 1 to Figure 6 , a kind of injection molding manipulator mold anomaly detection method based on LMDO, described anomaly detection method comprises following process:
[0037] 1) Collect the standard template image when the injection molding machine is in place, and perform preprocessing as the subsequent differential background image;
[0038] 2) Wait for the working status information of the injection molding machine. When it is detected that the injection molding machine is running to the mold opening position, the camera continuously captures images of the cavity surface of the mold, extracts the average image of several images, and preprocesses the average image. Prepare for subsequent image processing as the subsequent difference foreground image;
[0039] 3) Execute the LMDO-based anomaly detection algorithm on the differential foreground...
