In many batch or short-run productions are often needed nearly 100 percent quality checking of all parts of products, subassembly and finally even assembly which are going to distribution. One from the most difficult tasks in quality control process is detailed inspection, which should catch as production defects, like dimensions defects, such the defects of visage. Because this one the automatic quality inspection without doubt increase the productivity of process and increase the quality of production as well. Of coarse there is the accuracy problem of implementation this inspection, because the resolution of CCD sensors is final and relatively low for measurement. We was focused to find and try to put on the methods how to increase these limitation. We tried to develop the methods for increasing the resolution using the series of images that are combined to one high-resolution image based on extraction of information from random sub-pixel movement of these images. During our work were designed and tested the mathematical methods and program modules for programming environment Matlab. The programming modules together with digital camera and 2D automatic position table offer the snapping of images, random movement of images, registration of image’s shifting in image series and their interpolation to one high resolution image, which is consecutive send to program for image processing.
