Embodiment 1

[0055] Illustratively, figure 1A schematic flowchart of the state monitoring method of the mold provided in the first embodiment of the present application. The method of this embodiment can be executed by the state monitoring device of the mold provided by the embodiment of the present application, and the device can be implemented by software and / or hardware. , and can be integrated into the industrial computer. like figure 1 As shown, the state monitoring method of the mold of this embodiment includes:

[0056] S101. Acquire a template image of a target mold and an image to be detected.

[0057] In this step, when it is necessary to perform state detection on the target mold, the template image and the image to be detected of the same target mold collected by the visual imaging component are obtained, wherein the template image is the image of the target mold in a normal state, that is, when the visual imaging component is used When the quality of the target mold is inta...

Embodiment 2

[0082] The preprocessing process of the template image of the target mold will be described below through a specific embodiment, for example, Image 6 A schematic flowchart of the preprocessing process of the template image provided in the second embodiment of the present application, such as Image 6 As shown, in this embodiment, the preprocessing of the template image includes:

[0083] S201: Determine a pre-selected area of ​​the template image according to a frame selection operation performed by a user on the target mold in the template image on the human-computer interaction interface.

[0084] The industrial computer provided by this embodiment includes a human-computer interaction interface, and the user can view the image collected by the visual imaging component through the human-computer interaction interface, and perform corresponding operations on the image. In a possible implementation manner, in this embodiment, the region of interest of the template image is d...

Embodiment 3

[0097] Figure 7 A schematic structural diagram of the state monitoring device for a mold provided in Embodiment 3 of the present application, as shown in Figure 7 As shown, the state monitoring device 10 of the mold in this embodiment includes:

[0098] Image acquisition module 11 and image processing module 12 .

[0099] The image acquisition module 11 is used to acquire the template image and the image to be detected of the target mold; the template image is the image of the target mold in a normal state, and the template image includes an image of interest including the image of the target mold area;

[0100] The image processing module 12 is configured to identify and locate the image to be detected by using a pyramid template matching algorithm according to the region of interest of the template image to obtain the target area of ​​the image to be detected; According to the pixel difference existing between the regions of interest, the sensitive sub-region included i...

Abstract

The embodiment of the invention provides a mold state monitoring method and device, an industrial personal computer, a storage medium and a system, and the method comprises the steps of obtaining a template image of a target mold and a to-be-detected image, the template image being an image of the target mold in a normal state, and the template image comprising a region of interest of the image of the target mold; according to the region of interest of the template image, adopting a pyramid template matching algorithm to identify and position the to-be-detected image to obtain a target region of the to-be-detected image; determining sensitive sub-regions contained in the target region according to a pixel difference between the target region and the region of interest; and according to the area of the sensitive sub-region, determining whether the target mold is abnormal, so that automatic monitoring of the mold quality is realized, the real-time performance and the accuracy of mold abnormality detection are considered, and the mold monitoring quality and the production efficiency are improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of mold protection, and in particular, to a mold state monitoring method, device, industrial computer, storage medium, and system. Background technique [0002] In recent years, the increasing demand for injection molding products in the automobile, construction, household appliances, food, medicine and other industries has promoted the development and improvement of the entire injection molding and molding technology level, and also led to the development of the injection molding industry. In the injection molding industry, the mold is an important molding equipment, and its quality is directly related to the final quality of the product. Since the mold accounts for a large proportion of the production cost of injection molding, its service life directly affects the product cost. In order to protect the mold, it is necessary to monitor and detect the production status of the mold...
