and unstable accuracy in manual sorting of mechanical parts in traditional industry
a multi-point complex recognition and sorting system based on machine vision is designed from the perspectives of software and hardware deployment
so as to achieve the automation and intelligent upgrading of the sorting process.Following the logic of "acquisition-analysis-decision-execution"
the system collects workpiece images through an industrial camera.The images are preprocessed via grayscale conversion and filtering to enhance image quality and eliminate noise
which lays a foundation for subsequent recognition.Then
the sardine optimization algorithm-Otsu’s method(SOA-OTSU) algorithm is adopted to complete adaptive threshold segmentation.Finally
Blob connected component analysis is used to extract key information such as workpiece contour and center coordinates
realizing rapid recognition and positioning of the target. The processed workpiece information is input into an Arduino controller
which drives the robotic arm to complete the actions of grabbing
transporting
and placing.Experimental results show that the system effectively avoids human subjective errors
and significantly improves the sorting speed and accuracy
with the workpiece grabbing accuracy maintained stably at a high level.It fully verifies the feasibility and practicality of the proposed scheme
and the system demonstrates good application prospects.
