Embodiment 1

[0052] The main purpose of the image processing-based early warning method for structural parts production safety in the present invention is 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 idea of ​​the method is: analyze the real-time collected image of the target structural part, obtain the size information and edge information of the structural part, compare it with the standard information, and obtain the assembly matching degree; perform finite element analysis on the 3D model of the target structural part Analyze and obtain the assembly importance of each position of the structural parts during normal operation, and then set the threshold according to the assembly importance to realize the early warning of the production safety of the structural parts and eliminate the safety hazards generated during the a...

Embodiment 2

[0107] This embodiment proposes a safety early warning system for structural parts based on image processing, including a memory and a processor, and a computer program running on the memory and on the processor, the processor is coupled with the memory, and when the processor executes the computer program Realize the structural part production safety early warning method in embodiment 1.

Abstract

The invention relates to a structural member production safety early warning method and system based on image processing, and the method comprises the steps: obtaining an image of a target structural member, carrying out a series of processing on the image, and outputting an assembly edge region map of the target structural member; adjusting the size and the rotation angle of the image of the target structural member and the assembly edge region map, and calculating a difference image of the adjusted image of the target structural member and the template picture of the target structural member on the assembly edge region; according to the pixel value of each position in the difference image, determining the assembly matching degree of each position on the assembly edge of the target structural member, comparing the assembly matching degree of the assembly edge position of the target structural member with a set matching degree safety threshold, and carrying out safety early warning of the target structural member. The method can objectively evaluate the assembly matching degree of each position of the assembly edge of the target structural member in a certain process, achieves the safety early warning of the production of the structural member, and eliminates the potential safety hazards generated during the subsequent assembly of the structural member.

Description

technical field [0001] The invention relates to the technical fields of artificial intelligence and image processing, in particular to a method and system for early warning of structural component production safety based on image processing. Background technique [0002] Structural parts are components with a certain shape and structure that can bear 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-scale equipment such as airplanes and bulldozers, it is composed of tens of thousands or even hundreds of thousands of structural parts. The production process of structural parts is composed of many different processes, mainly consisting of materials, Cutting, forming, straightening, edge processing, hole making, and assembly are composed of links. Problems in each link will affect the final assembly effect, especially in the processes of cutting, edge proces...
