Embodiment 1

[0052] An image processing-based production safety warning method for structural parts of the present invention mainly aims to detect potential safety hazards of structural parts during the production process of structural parts, so as to prevent the safety of equipment from being affected in the subsequent assembly process. The inventive concept of the method is as follows: analyze the real-time acquisition of the target structural part image, obtain the size information and edge information of the structural part, compare with the standard information, and obtain the assembly matching degree; perform finite element analysis on the three-dimensional model of the target structural part Through analysis, the assembly importance of each position of the structural parts during normal operation is obtained, and then the threshold is set according to the assembly importance, so as to realize the safety early warning of the production of structural parts and eliminate the potential sa...

Embodiment 2

[0107] This embodiment proposes an image processing-based structural component production safety early warning system, including a memory and a processor, and a computer program on the memory and running on the processor, the processor is coupled with the memory, and when the processor executes the computer program The method for early warning of structural component production safety in Embodiment 1 is realized.

Abstract

The invention relates to a method and a system for early warning of structural parts production safety based on image processing. The method obtains an image of a target structural part, performs a series of processing on the image, and outputs an assembly edge area map of the target structural part; adjusts the image and The size and rotation angle of the assembly edge area map are calculated, and the difference image between the adjusted image of the target structural member and the template image of the target structural member on the assembly edge area is calculated; according to the pixel values ​​of each position in the difference image, the target structural member is determined. The assembly matching degree at each position on the assembly edge is compared, and the assembly matching degree at the assembly edge position of the target structural part is compared with the set safety threshold of the matching degree to carry out the safety warning of the target structural part. The invention can objectively evaluate the assembly matching degree at each position of the assembly edge of the target structural part in a certain process, realize the production safety early warning of the structural part, and eliminate the hidden safety hazards during subsequent assembly of the structural part.

Description

technical field [0001] The invention relates to the technical fields of artificial intelligence and image processing, in particular to a method and a system for early warning of production safety of structural parts based on image processing. Background technique [0002] Structural parts are components with a certain shape and structure that can withstand loads, and are widely used in the fields of construction engineering and automobile manufacturing. With the development and innovation of mechanical equipment, for a large equipment such as an aircraft and a bulldozer, it is composed of tens of thousands or even hundreds of thousands of structural parts. It is composed of cutting, forming, straightening, edge processing, hole making and assembly. Problems in each link will affect the final assembly effect, especially the cutting, edge processing and hole making of structural parts. Mass production of structural parts that do not meet the requirements will bring serious ec...
