A Research On IR/SAR Image Simulation, Collection And Transmission Technologies For Image Fusion Applications

Multi-source image fusion has a widely application prospect in military field，Due to the different image sensor on the collected images have their own advantagesand disadvantages，By means of multi-source image fusion can make up for eachother of each sensor faults，And how to apply the advantages of multi-source imagefusion in military target recognition is an important research，The premise of imagefusion research heterogeneous sensor is to be able to obtain different sensor imageseffectively，This article revolves around the key technology of infrared/SAR imagefusion application oriented research work，To study heterogeneous sensor images areon the same target, but the same scene from different perspectives of SAR image andinfrared image collected respectively，Research priorities include from two aspectsof simulation and real-time acquisition for sensor images， And on the basis ofsuccess for sensor image sensor image data transmission.In this paper, the main research results and work is as follows:First of all, Research on infrared/SAR image simulation work, According to theideas of the hardware-in-the-loop simulation from has access to the real imagesensor using the Creator and Vega modeling simulation software simulation to getthe same scene, but the corresponding sensor images under differentperspectives.With tank model as an example this paper introduces the basic processof Creator of3d modeling, Using atmospheric transmission tools MAT set theatmosphere environment parameters, Materials through the TMM texture mappingtool to complete the3d model of texture and texture mapping, Then using Vegacompleted the infrared/SAR image simulation, Solved the tank track special effectsin the infrared image simulation image, aircraft tail flame effects image acquisition,SAR image simulation of SAR image simulation results under different parametersare obtained.Second, At Texas instruments DM6446DaVinci image acquisition system onthe basis of research on real infrared image acquisition was carried out, Include thebasic architecture of the hardware, the basic process of infrared image acquisition,H.264decoding algorithm and codec engine, as well as the design of the application,Successful collected real-time infrared image. In the end, Carried out the sensor image data transmission equipment softwaredesign work and construction of the hardware platform, on the basis of geting realimage sensor and the simulation image, Studied how to obtain image datatransmission to the server quickly and efficiently, Use of independent research anddevelopment in this lab, a portable network equipment to transmit image data, Thisequipment is a set of integrated various communication modes of the portablecommunication terminal, In the complicated and changeable external environmentquickly and reliably to form a communication network, Make full use of the mostcommonly used in the existing civil network, Including GPRS、 CDMA wirelessnetwork and wired Ethernet network.Then use the Java language to write the clientand the server PC software，Solve the sensor multithreaded programming problemsin image data transmission, combining with the portable communication terminalsoftware, this paper expounds the terminal parameters configuration and basic useprocess, The experimental results show that can successfully sensor image datatransmission to the server.
