Detection and identification method for circular high-reflection workpieces

Abstract

The invention relates to the technical field of visual inspection, in particular to a detection and identification method for a circular high-reflection workpiece, which comprises the following stepsof: 1, performing image acquisition on the workpiece; 2, performing binarization processing on the acquired image; 3, performing spot detection algorithm operation and circular detection algorithm operation on the binarized image, and identifying whether a workpiece has defects or not and identifying circular size information on the workpiece; and step 4, converting the judgment result of whetherthe workpiece has defects or not and the identified circular size information into readable data information and outputting the readable data information. The display interface displays the acquired image and defect position and size information marked on the image, so that an operator can conveniently and quickly know the detection condition of the workpiece, the whole steps are simple, conventional technicians can conveniently and quickly master skilled work, and the operation efficiency is indirectly improved.

Description

technical field [0001] The invention relates to the technical field of visual inspection, in particular to a detection and recognition method for a round highly reflective workpiece. Background technique [0002] The feature of machine vision inspection is to improve the flexibility and automation of production. In some dangerous working environments that are not suitable for manual work or where artificial vision is difficult to meet the requirements, machine vision is often used to replace artificial vision; at the same time, in the process of mass industrial production, the efficiency and accuracy of using artificial vision to check product quality is low. , the use of machine vision inspection methods can greatly improve production efficiency and production automation. Moreover, machine vision is easy to realize information integration, and it is the basic technology to realize computer integrated manufacturing. Visual inspection is to use machines instead of human eye...

Problems solved by technology

[0003] As mentioned above, visual inspection has a huge market value. The core of the visual inspection system is not the hardware equipment but the algorithm steps. Factors such as capabilities vary widely. If the design of the core algorithm steps is lacking, it will affect the operating efficiency and quality of the entire set of visual inspection equipment. In the algorithm steps of circular highly reflective workpieces, most of the technical solutions on the market are expensive to use. At the same time, the algorithm steps are relatively complicated, which is not conducive to the general technical personnel's routine parameter change and other operation settings.
