Abstract

In order to determinate image size or position in opto-electronic image measurement, it is important to determinate image edge positions. Optical diffraction and the presence of variable filtering process make the image edge blurring, thus the determination of edge position is difficult. The formation and transmission process of electronic image by opto-electronic measuring system using CCD as detector attempt to be analysed, and a mathematical model to be defined in this paper. Edge position will be defined by calculating the point amplitude values of image edge, and the effects of the system parameters on the measurement of edge position will be found out.
