基于机器视觉的柑橘果形测控系统设计
Design of Citrus Fruit Shape Measurement and Control System Based on Machine Vision
摘要
Abstract
Aiming at the problems of low detection accuracy of roundness and fruit diameter and long attitude positioning time in citrus fruit shape features,an embedded fast detection and control system was designed.The system used STM32 micro-controller as the system control core,and measured the radius error and shape error of the monocular camera im-age.The dynamic citrus images were processed in real time using Gaussian filtering,digital image morphology,Hu mo-ments and Canny algorithm.Experiments shows that the radius error of the visual detection system is controlled within 1.8%,and the shape error is 2.71%-3.69%.Under the conveying speed of 5 citrus per second,the online grading ac-curacy of citrus roundness and fruit diameter are 81%and 91.92%,respectively.This study combined the machine vi-sion non-destructive testing technology to realize the comprehensive detection and classification of citrus roundness and fruit diameter characteristics under dynamic conditions.关键词
