Measurement of Worn Drill Bit Size Based on Edge Detection of Gradient Algorithm

In this paper, a gradient algorithm is proposed to measure the length of the drill bit. First, the image is obtained by using CCD, Then do a series of preprocessing such as grayscale, binarization, image denoising. Then Use gradient algorithm to further process the picture to get the edge contour of the drill bit. Finally, we can complete accurate measurement by positioning the end and tail of the drill bit.
