Paper Abstract

This paper presents a new method of high-precision calibration with grating grooves for precision vision measurement system of micro-size part. After an image of high precision grating grooves are grabbed by CCD, a black-and-white striped picture may be gotten. A group of data being similar to sinusoid is gotten by calculating the sum of gray-value of pixels in each column. These calculated data are elaborately showed a Lissajous figure in one plane by translation for pixel. The size mapping coefficient between the grating groove and their image pixels of the optical measurement system is calculated by analyzing and processing the Lissajous figure. It is not necessary to calculate the interior and exterior parameters of the camera for the calibration of measurement system when this method is adopted. Finally, this paper gives the result of calibration and its error analysis for one optical system.
