Embodiment

[0053] An image dynamic detection system based on FPGA+ARM, including ARM processor and FPGA, ARM processor as the system controller, and completes the interaction of the application layer; FPGA completes the initialization, control and edge detection processing of the COMS sensor. The camera collects the image analog signal, converts it into a digital image signal, then optimizes the digital image signal processing, and finally converts it into an analog signal and displays it as a video. Among them, the edge detection algorithm outlines the shape of things and determines the shape; the interpolation method is used to detect moving objects and locate them.

[0054] A kind of image dynamic detection method based on FPGA+ARM, comprises the following steps:

[0055]Add ZYNQ7Processing System IP, make the interface of S_AXI_HP0_Interface effective, enable the Uart port, set two clocks, one 100Mhz, used for register reading and writing and control of peripherals; the other 150Mhz,...

Abstract

The invention discloses an image dynamic detection system and a method based on FPGA + ARM. The system comprises a COMS acquisition circuit, a zynq processing circuit and an HDMI display circuit. A COMS acquisition circuit is connected with a camera, and is used for video acquisition to form a digital image, and then that signal is transmit to a zynq processing circuit. The Zynq processing circuitconsists of FPGA and ARM. The FPGA is used to receive and transmit signals, and the edge detection algorithm is put into the FPGA as IP core. The ARM part stores an interpolation method. The HDMI display circuit is connected with that display for displaying video. Based on FPGA and ARM, the invention realizes fast image acquisition and processing.

Description

technical field [0001] The invention relates to digital image acquisition and processing technology, in particular to an image dynamic detection system and method based on FPGA+ARM. Background technique [0002] With the rapid development of science and technology, digital image acquisition and processing systems are more and more widely used in scientific research, industrial production and daily life. In today's consumer market, there are more and more electronic products with image display functions, including videophones, digital cameras, access control systems, and security monitoring systems. [0003] At present, digital image acquisition and processing technology is developing in the direction of real-time, large capacity, and miniaturization. Due to the large amount of data in the image processing algorithm implemented by general software, it is relatively slow to implement and has low real-time performance. Embedded image acquisition And processing is becoming more...
