On the basis of an optical modulation model and a normalized correlation model, an objective evaluation method for the resolution of a low-light-level image intensifier was explored by using the dual criterion of template matching and optical modulation as core algorithms. A set of resolution objective evaluation system for the low-light-level image intensifier was constructed. In the method, the optical modulation model and the normalized correlation model are independent of each other and also cannot be separated from each other. Firstly, the template matching coefficients in the normalized correlation model were used to performed the location and preliminary evaluation , then the optical modulation model was taken to do a quantitative analysis. The image processing scheme in first qualitative analysis then the quantitative analysis improves the accuracy and repeatability of resolution test for the low-light-level image intensifier, implements the objective and accurate evaluation for low-light-level image intensifier and avoids the shortcomings of visual observation method which is influenced by human's subjective factors. The experiments demonstrate that the resolution of the image captured by CCD has good consistency with that of visual observation result by human eyes. The method is also suitable for the evaluation of resolutions of other visible light imaging systems.
