Measurement and application of compacting section of stem cutter based on machine vision
摘要
Abstract
To measure the effectiveness of the compaction section on stem-cutters and study its influences on the quality of the cut stems,machine vision technology was used to capture images of the compacting section,convert them into point cloud maps,and apply GrabCut segmentation.Total variation extraction and standard score conversion were performed for the quantitative measurement of the compaction section on the stem-cutter.Besides,standard score of total variation was employed for auxiliary evaluation and verification for the weights of post-cutting slivers and thickness uniformity.The findings are as follows:(1)The total variation standard score P and measurements of machine vision meet the relation P=0.05RvB/Rv(x);(2)the coefficient of total variation standard score P in different measurement angles ranges from 0.27%to 1.29%.At the same time,when measuring the stem with different compression sizes,the coefficient of total variation standard score P measured is between 0.25%and 1.37%,indicating that the method meets the accuracy requirements for quantitative analysis;(3)As the total variation standard score PPP increased,the compacting effect of the section improved,the stem removal amount decreased by 47.15%,the stem width qualification rate increased by 21.95%,and the standard deviation reduced from 0.024 mm to 0.013 mm.This method provides reliable descriptive capability for the compacting section and can effectively evaluate the compacting effect,assisting in inferring the quality of cut stems.关键词
