The Target Localization Algorithm And Image Fusion Algorithm Based On Dm6467 Research

The target location accuracy can be greatly increased by the combination of beidou satellite positioning and monitoring screen.It has a strong potential application in military field such as high precision strike weapons,field command and dangerous works of engineering measurements. With improvement of the video processing chip performance,it is possible to realize complex image fusion algorithm in hardware system.In this paper the target finding algorithm and pyramid image fusion algorithm are studied in image processing and control calculating hardware system using TMS320DM6467as core processor.Fistly relevant technical background and the background of the paper are introduced,main content and frame structure of the paper are explained.All algorithms are realized in image processing and control calculating system which is developed by422Teaching and Research Section.The design of hardware system is introduced in second chapter,core processor DM6467and video decoder TVP5158are introduced in detail.Based on the study of the target location algorithm’s theory,the mathematical model is established,tested and error of the results are analysed,then the algorithm is programmed and realized in Linux system on ARM end of DM6467.Monitoring screen composites both infrared image and white image’s advantages by using the laplacian pyramid image fusion algorithm.By the study of the pyramid image fusion algorithm,tower decomposition and reconsruction process are established,based on appropriate fusion rules the laplacian pyramid image fusion alogorithm is simulated by using MATLAB. Application program is designed to realize the algorithms after completing theoretical work.DM6467is a ARM+DSP dual core processor,ARM end is mainly responsible for the overall control functions,including the capture and display function,menu display,and serial interface information processing to finish the target finding algorithm. Video processing functions is completed by DSP end,by using DVSDK,the laplacian pyramid image fusion algorithm with XDM standard can be complied.Only part window of the images are fused to achieve real time video display.Finally the program is debugged in image processing and control calculating hardware system and launched itself off-line by Nand Flash.
