Abstract :
This paper designs an event triggered and non-destructive readout industrial intelligent camera (ETNDRIIC) that can be used in auto manufacturing systems. The main hardware of an ETNDRIIC includes DSP, FPGA, CMOS, and DM9000. FPGA is used as an interface between DSP and CMOS, and it is easy for an ETNDRIIC to support different image sensors with different driven processes. In this system, a new, optimized algorithm, a restricted Laplacian sharpening algorithm, is adopted and is realized in DSP. The noise of image is depressed effectively through the algorithm and edges of the image after processing the images is distinct, the details are also observed. The Ethernet interface is integrated to implement a long-distance image transmission. It is more convenient to build a network with the camera for any complex auto manufacturing systems, which need more image information. It is proved that an ETNDRIIC is an advanced piece of equipment that is able to gather industry images for measuring.
