Realization of Logic Control of Acquiring Image From Linear CCD Camera Based on FPGA
ABSTRACT: Using on-line system for detecting textile fabrics defect as an application background, the research and development of logic control of acquiring image from linear CCD camera based on camera link protocol was discussed in this paper. Design and implementation of logic control of signal transform interface, logic control of assembling frame images and synchronizing data sampling of images from linear CCD camera based on FPGA were presented briefly, and their simulated results were given.
