【Abstract】 A system for high precision measurement of cutting tools is described .The tools are backlit by incandescent lamps. Images are acquired from a digital camera and are trasmitted into a computer through USB interface. The image analysing programs extract the profiles of cutting tools using Zernike orthogonal matrix algorithm and calculate geometrical parameters accurately, which are outputed from a serial port . Zernike orthogonal matrix algorithm is described in detail.The analyse is for real data indicates that this system has a precision of 4 μm.更多还原
