Design and implementation of PCI bus infrared image acquisition system based on FPGA

In order to meet the requirement of image acquisition and testing of infrared imaging equipment with special data format, a PCI bus image Acquisition system was developed. The Field-programmable Gate Array (FPGA) chip is used as the main controller to realize signal acquiring and data processing, and PCI9054 is used to translate the data to the host computer of the system. The host computer identifies the head and tail of frame data according to the communication protocol, reconstructs and displays the image. The experiment results show that when the resolution of image is 128 X 128 , pixel grayscale depth is 16 bit, the system can acquire the infrared image with the speed 100 fps stably, and the design satisfies the requirement of using.
