Real-time Artillery Experiment Image Acquisition And Processing System Based On FPGA

Artillery test is to promote an important part of the national defense science and technology progress. Research on the acquisition and processing of the artillery test data, can promote the development of informatization and artillery test to the intelligent direction. At present, artillery test data collection generally use IC control circuit.In gun bore flaw detection and the gun muzzle vibration measurement test, researchers need to image data acquisition and processing of the artillery testing. In this paper, we design a real-time image acquisition and processing system based on the acquisition and processing of the artillery test image. The System uses the FPGA chip EP4CE15F17C8 as the core control device, select OV7670 CMOS camera as a collection of components, the use of SDRAM as cache on chip and select ADV7123 as video coding chip, using the VGA circuit as a display element. Through these chip component realizes the hardware circuit is built, and based on the hardware circuit design of software design, the use of Hardware Description Language Verilog HDL to complete the software design of image acquisition and image processing. Design and implementation of CMOS sensor I2C initialization, camera data acquisition, SDRAM burst read and write the function of image acquisition control, complete the classical Gaussian filter, fast median filter, Sobel edge detection algorithm, the traditional Canny edge detection algorithm and an improved Canny edge detection algorithm for FPGA implementation.Through the use of Quartus Ⅱ logic analyzer SignalTap Ⅱ waveform simulation of the real-time image acquisition and processing system of each software module, and completed the functional verification of software module of image acquisition and image treatment. Finally, the hardware experiment of image acquisition and processing system is carried out under laboratory conditions.
