Improve Aircraft Cockpit Display System Compass Screen Display Quality

The graphics display plays more and more important role in the Electronic Flight Instrument System. The complex situation of flight requests that the graphics display of cockpit must be dynamic,real-time and legible.But in the raster graphic display system,scale lines and character will be distorted seriously owe to the limited screen resolution in the case of deflection,which affect the display quality.The thesis based on the research of the last graduate student improves the graphics creating arithmetic more and puts forward more effective arithmetic on scale lines and character for high display quality.The thesis put emphases on dissertating the arithmetic of antialiasing rotation of the compass scale lines,small character and the technology of animated drawing when the compass is rotating.At the same time,the program of the compass picture is offered.
