The Design And Realization Of Dynamic Virtual Landscape

UAV(Unmanned Air Vehicle) has many advantages, such as good invisibility, strong flexibility, and low cost. More important, no pilots will die using UAVs. In modern war, UAV is more and more widely used. UAV composes of many complex devices, which is very expensive. If using real UAV in trainning, we have to face a high cost, a serious risk, and a limit of aerial condition and weather. The developping "Simulating Trainning System of UAV" has the same characteristics of operation and display as real UAV system. It can simulate the whole process of flying. An important component of it is the simulation of reconnaissance image.In this article,the author gived out a project on 3D modelling basing on the analysing of the characteristic of UAV s reconnaissance image. With moving models, a good real-time simulating reconnaissance image has been accomplished. Furthermore, a network model and a serial-port model are employed to implement the commucation within system, which is also referred in this article.
