Abstract:
1. A method for extracting parameters of a cutting tool, the method comprising: positioning the cutting tool on a moveable stage; performing one or more rotary scans of a first section of the cutting tool to generate a scanning point cloud; indexing a plurality of points of the scanning point cloud; detecting one or more feature points based on the indexed scanning point cloud; and extracting one or more parameters based on the detected feature points, wherein performing one or more rotary scans of the first section to generate the scanning point cloud comprises performing a first rotary scan of the first section to generate a first scanning point cloud, segmenting the first scanning point cloud, and performing a second rotary scan of the first section based on the segmentation of the first scanning point cloud to generate a second scanning point cloud, and wherein the scanning point cloud comprises the second scanning point cloud.
