Research on Measurement Technology of Tool Geometry Parameters Based on Image Processing

The tool length, diameter, radius, and angles of the two blades can be measured automatically using image processing techniques such as image pre-processing and edge detection. Using the Delphi Platform, measurement software based on image processing is developed, which can detect geometric parameters of tools, achieving the automation of geometric parameter measurement. The binarization, median filtering, edge detection, contour extraction,parameter extraction and other image processing technology are applied. By high resolution CCD camera and optical amplifying system, tool geometry can be measured to meet the high-precision measurement of high degree of automation, repeatability and good demand.
