Abstract
In order to improve the display effect of anti-aliased symbol and video superposition in the airborne head-up display system,a kind of anti-aliased symbol and video overlay algorithm is proposed and is realized on FPGA.By adding the background fusion calcula-tion,the adj acent edges of anti-aliased symbol and video is smooth.Two DDR3 are used to store the video and graphic data respectively, both parallel process to improve the overall performance of the system.Optimization of the implementation process of background fusion algorithm,the complexity of the DDR3 interrupt is reduced.The experiment results show that the overall performance of the system is improved,and the overlay fusion image has good effect and high flexibility,which is suitable for the display system of the airborne cockpit.关键词
