[0030] like figure 2 A flow chart provided by an embodiment of the present invention is shown. See figure 2 , the mold detection method includes:

[0031] Step S110: Obtain an image of the mold to be inspected during the working process of the mold.

[0032] In the embodiment of the present invention, the mold detection method can be applied to detect whether there are foreign objects in a dynamically working mold.

[0033]During the working process of the mold, the image of the mold can be collected in real time through the camera. In addition, the camera can collect the image of the mold during work according to a certain frequency. After the image of the mold is collected, it is judged whether there is foreign matter in the mold according to the collected image. The image collected above is the image of the mold to be inspected during the working process of the acquired mold.

[0034] Step S120: Obtain a matching background image that matches the image of the mold to...

Abstract

The invention provides a mold testing method, a device thereof and electronic equipment, wherein the method, the device thereof and the electronic equipment relate to the field of mold testing technology. The mold testing method comprises the steps of acquiring a matched background image which matches a to-be-tested mold image in a plurality of prestored background image, wherein the background image is the image on the condition of no foreign matter in a working process; performing transformation processing, normalization processing and cutting processing on the to-be-tested mold image and the matched background image based on the matching matrix of the to-be-tested mold image and the matched background image, and obtaining a first mold image and a first background image; obtaining a first differential image of the first mold image and the first background image, performing threshold segmentation on the first differential image and communicating area screening, and obtaining a first area image; determining whether the pixel value of pixels in the first area image is zero; and if not, outputting information that the foreign matter exists in the mold. The mold testing method can realize automatic testing for the foreign matter of the mold.

Description

technical field [0001] The invention relates to the technical field of mold detection, in particular to a mold detection method, device and electronic equipment. Background technique [0002] In recent years, with the advancement of mold design and manufacturing technology, as well as higher requirements for process automation, high precision, high efficiency and long life, various molds have been vigorously developed. They are used in automobiles, aerospace, instruments, household appliances, It is widely used in the production of products in many fields such as electronics, communications, military industry and daily necessities. For example, progressive die is an important stamping equipment for semi-automation and automation, and it is an advanced mold structure to ensure stable processing quality. [0003] In actual production, manual monitoring of the internal state of the mold is mostly adopted. The operator mainly observes the internal condition of the mold visually...
