Design of Endoscopic Image Processing System Based on ZYNQ
In order to solve the problems of large size and high cost of traditional medical endoscope system,an endoscopic image processing system based on ZYNQ is designed and implemented in this paper.The system uses the ZYNQ7020 launched by Xilinx as the main control chip,OV6946 is the image acquisition camera,OV426 is the image decoding chip,the FPGA is the im-age processing terminal to receive the RAW format image,remove the image bad pixels and do color interpolation to convert to color RGB image,then do white balance processing to restore the real color of the image,and finally enhance the image contrast to im-prove the visual effect,the image is stored in DDR3 through the AXI bus,and finally displayed through HDMI.The PS side initializ-es the FPGA configuration to assist in image acquisition and storage.From the test results,it can be concluded that the design of the system is simple,the resources are less,the processing time is high,the image processing results meet the expected requirements,and have a good application prospect.
