Description

technical field [0001] The invention belongs to the field of embedded machine vision, and more specifically relates to an industrial intelligent camera using an FPGA chip as a main processor and a CMOS image sensor as a photosensitive chip. Background technique [0002] At present, most machine vision systems use PC-based vision systems, which usually include industrial cameras, lenses, image acquisition cards, image processing software packages, and general-purpose computers or industrial computers for image processing. Video images are converted through image acquisition cards Send the digital signal to the computer for processing. Users can choose different image acquisition cards and computers according to their needs and performance differences, and implant corresponding algorithms in them. The PC-based vision system has the advantages of high versatility, flexible configuration, and easy implementation, but it also has defects such as large volume, high power consumpt...
