A new non-contact tool 3D geometry measurement system based on machine vision is described. In this system, analytical and optimization methods are used respectively to achieve system calibration, which can determine the rotation center of the drill. The data merging method is fully studied which can translate the scattered different groups of raw data in sensor coordinates into drill coordinates and get 3-D topography of the drill body. Corresponding data processing methods for drill geometry are also studied. Statistical methods are used to remove the outliers. Laplacian of Gaussian operator are used to detect the boundary on drill cross-section and drill tip profile. The arithmetic method for calculating the parameters is introduced. The initial measurement results are presented. The cross-section profile, drill tips geometry are shown. Pictures of drill wear on drill tip are given. Parameters extracted from the cross-section are listed. Compared with the measurement results using CMM, the difference between this drill geometry measurement system and CMM is, Radius of drill: 0.020mm, Helix angle: 1.310, Web thickness: 0.034mm.
