The Design Of Map Track Display System Software For Multi-UAV

With the increasingly close integration of track display and digital map,digital map has become an indispensable part of the track display system and the basis for all follow-up work.This thesis aims to design a multi-UAV map track display system to realize terrain threat modeling,map display and multi-UAV track display functions.This system is based on Windows7 operating system,with Visual Studio2010 MFC library functions,combined with Arc Engine10.1 development package and Open CV2.4.9 library functions to build a two-dimensional visualization platform.Among them,the terrain threat needs to use the Open CV library function to complete the data acquisition and processing under MFC,and finally the threat model is displayed on the vector map.The functions of map display and track display are achieved through secondary development of Arc Engine with VC++/MFC.The digital map in this thesis is divided into vector map and digital elevation map.Vector map is the map of the front desk,and the digital elevation map is the backstage map.According to the data structure characteristics of he digital elevation map,the terrain threat is modeled using Open CV library functions.The modeled graphics are divided into circle and rectangle.The map display function is to load the vector map in the system initialization interface,which is derived from the Google map without offset.Using Arc Map software to label the geographic names and select the regional ribbons,and the vector map is displayed by using the Arc Engine component technology.At the same time,points,lines,geometry,and text also need to be plotted on the vector map.The multi-UAV track display includes two parts: map display operation and track display function.The map display operation can not only display labels for waypoints,but also perform operations such as zooming in,zooming out,and panning the vector maps.The track display function is to connect a series of discrete waypoints to obtain clear,easy-todifferentiate multi-UAV routes with configurable track colors and editable machine numbers.Finally,the system functions,such as the terrain threat modeling,map display and track display are verified by example.The result shows that the system design functions meet the requirements.
