基于计算机视觉的成熟番茄识别研究
Research on Recogniztion of Mature Tomato Based on Computer Vision
摘要
Abstract
Takes the image of tomato as the research object and proposes a new kind method of recognizing mature toma -to.First, takes the Hue of the HSI model as basis to make image segmentation to extract the image of mature tomato and use the maximum variance automatic threshold to make segmentation .The paper use the Hough transformation to recog-nize the contour after extract it from the target image and set the mean value of several maximum points of one contour as the value of recognition .Before the Hough transformation it use the minimum bounding rectangle ( MBR ) to marked the effective region , and this makes the Hough transformation effectively .A plenty of images of tomato was take into simula-tion test , the algorithm in this paper has the result as follow:78 .7%with the fruit cover rate 0%, 68 .1%with the fruit cover rate less than 50%and 41.9%with the fruit cover rate more than 50%.The average recognition rate reached 70.6%, The algorithm proposed in this paper can recognize the mature tomato accuracy , especially for the covered tomatoes , the recognition is accuracy .关键词
