基于VAPS虚拟仪表反走样设计仿真实现

Design and simulation of virtual instrument anti-aliasing based on VAPS

针对飞机模拟机虚拟仪表设计仿真时存在刻度线走样、刻度线位置不准确以及会产生锯齿现象等缺陷而进行反走样技术研究,提出区域采样技术和Bresenham反走样算法结合,重点在刻度线、字符的反走样技术上对其进行优化设计与研究,提高虚拟仪表画面的显示质量。通过VAPS软件完成了虚拟仪表设计与仿真。试验表明,该算法能够在虚拟仪表研发中实现反走样设计,达到飞机机载电子显示系统对其性能的高要求和标准。

There is scale line aliasing, line position calibration inaccurate and produce sawtooth appearances when this flight simulator for the design and simulation of virtual instrument. For these, the anti-aliasing technology is launched in the paper and the regional sampling and anti-aliasing algorithm Bresenham are combinated for the paper character anti-aliasing technology to opti- mize their design and research to enhance the display quality of the virtual instruments. Design and simulation of virtual instru- ments are completed through the VAPS software. Experiments show that the algorithm can achieve in a virtual instrument developed anti-aliasing design to achieve the aircraft airborne electronic display system on the performance of the high requirements and standards.
