Dynamic 3D Complex Scene Perception And Its Enhanced Synthetic Vision Technology

The 21 st century,the rapid development in the field of aviation technology,helicopters,passenger transport machine,drone aircraft in the field of military and civil application aspects,such as playing an increasingly important role,with the expansion of the navigation and flight demand increased,aircraft flying the scene is more and more complex,accident rates do not fall high,how to improve the situational awareness of aircraft operators outside scene has become a very important topic of research significance.At first,this paper analyzes the dynamic three-dimensional complex scenes along the flight safety factor,according to the current pilots in flight phase of the urgent demand,put forward the dynamic three-dimensional complex scene synthesis of visual perception and enhance technical solutions,and then combined with the project progress and related research results at home and abroad,this paper introduces the key technology need to be solved in the solution of various problems as well as the realization method of final design for more than a screen,multi-channel,multiple points of view of integrated real-time visualization demo system to verify the validity and practicability of the solution.The basic work done in this paper is as follows:1.Combined with the practical application of dynamic three-dimensional complex scene visual perception and enhance synthesis technology this solution are analyzed,in order to improve the practical application value of research,this article finally selected hardware research platform for a new generation NVIDIA Jetson TX1 embedded Linux development platform,the platform closer military embedded Linux system,a higher application value.2.In this paper,the dynamic three-dimensional complex scene perception technology has made the relevant analysis and research,this paper introduces the dynamic 3D complex scene and the key technique of perception,using 3D scene modeling technology to create the database in this paper,the topographic database and obstacles;The visual environment of rain,snow and fog was created by using complex 3D scene visualization technology.The imaging effects of forward-looking infrared,lidar and millimeter-wave radar are simulated by multi-source sensor sensing technology.The fusion effect of various sensors is demonstrated by using the sensor fusion sensing technology to enhance the situational awareness of pilots in complex 3D scenes.3.In this paper,the technology of enhancing synthesis of visual research and analysis,this paper introduces the enhancement synthesis technology route,visual enhancement is studied the key technique in the synthesis of visual,terrain tips and warning technology is applied to realize the mainstream of the terrain warning system,the 3D scene terrain texture shows a wide variety of pattern and color,highlights the terrain ups and downs and dangerous area;The obstacle perception and highlight technology are used to highlight the dangerous obstacles in the 3D scene through wireframing,distance marking and coloring.Using flight instruments,landing landmarks and safe flight channel show virtual military elements such as flight state parameter and landing location information,flight planning security channel,the auxiliary pilot and low altitude cruise phase of flight landing decision,to ensure the safety of the flight.4.was designed and implemented many screen,multi-channel,many of the viewport comprehensive real-time visualization demonstration system,this paper introduces the application of comprehensive demonstration system related technology,and will be subdivided into several functional modules integrated demonstration system,detailed introduces the comprehensive demonstration system implementation effect of the interface of the layout and function module.Verified by comprehensive demonstration system in this paper provides the design scheme of can very good improve pilot situational awareness under complex 3D scene,so as to prove that the research of this study is of important significance and application value.
