Abstract

In the design of industrial camera systems, it requires high video image quality, fast frame rate and real-time video image processing. The FPGA has the advantages of parallel processing, abundant resources and field programmable, it provides a hardware implementation platform for real-time industrial camera system design. This paper uses FPGA, CMOS image sensor, DDR3 SDRAM memory and USB3.0 chip to realize system function design of video acquisition, image preprocessing, image cache and image transmission. Video acquisition uses Sony IMX455 image sensor to acquire video images. Image preprocessing uses Microsemi FPGA to realize data deserialization and hardware ISP functions. Image cache uses DDR3 SDRAM memory to achieve multi-frame image cache. Image transmission uses USB3.0 chip to transmit image data to the host computer. The experimental results show that the industrial camera system only uses a single FPGA to complete image sensor control, high-quality image preprocessing and real-time image cache, which can stably obtain 9568*6380@6.4fps video images.
