Industrial array camera can accurately and efficiently locate any element in the image. At present, it is widely used in the surface quality inspection of various steels in the steel industry. The combined application of 2D and 3D camera can capture the surface image of special steels in real time and transmit the terminal for AI data analysis in real time. Can also be used as a teaching, personal experimental tool. It is an industrial camera with extremely fast speed and strong image capture ability.
