Tooth Width and Pitch of Circle Saw Blade Research Based on Vision Measurement
Yang Ku · Machinery Design and Manufacture · 2014
The uneven length of saw tooth width and pitch affect their using time seriously,but the inspection of saw blade is all artificial,restricting production efficiency severely. It combines the rounded contours of circle saw blade with manual measurement characteristics,proposing a new method of measuring tooth width and pitch of circular saw blades based on vision measurement,which uses techniques including threshold segmentation,feature extraction,morphology and sub-pixel precision. Finally it got the smooth contours of the saw blade,obtained the number of teeth,tooth width and pitch length. By analyzing the experimental results,the average error of the method is 0.678 pixels,and estimation error is 0.068 mm. It can be used in high-precision measurement occasions and has instructive significance to many other objects' vision measurement.
