Research on Real-time Edge Detection Control System Based on FPGA
This paper belongs to the field of image recognition processing technology,and proposes a real-time edge detection control system based on FPGA.In this paper,FPGA is used to configure the register of the camera,collect and obtain the original image,perform digital image grayscale processing,mean value filtering,sobel edge detection and calculation,binary processing,and then convert it into RGB,extract the image edge track of the target image,cache the image edge data into the DDR,and process the DDR read-write control module inside the FPGA,The DDR internal image data is converted to RGB format,and the edge of the target image is displayed in real time through the HDMI display.In this paper,the improved sobel edge extraction algorithm is used to refine the edge width,remove false edges,and filter out redundant image noise,so that the output edge image is more consistent with the actual edge information.
