| 摘 要： | 电子航图在飞行仿真领域有着重要应用,然而由于局部纸质航图尺寸、来源及扫描设备等因素的影响,扫描得到的各个子航图颜色不一致,严重影响航图的整体效果.因此本文重点讨论了电子航图的颜色校正问题,利用相郊子航图间的重重叠域,采用线性映射变换的方法,在RGB、YIQ、YUV、HIS 4种颜色空间下对电子航图进行校正和比较.实验结...

| Abstract: | Electronic chart has important application in the field of flight simulation.The colors of the scanned sub chart differ from each other due to the partial paper chart’s size,source,scanner and so on,which has a strong impact on the visual effect of the whole chart.The paper elaborates on the color correction of electronic chart.The contiguous sub charts’ overlapped area and linear mapping transform is used to correct electronic chart in the RGB,YIQ,YUV,HIS space.The experiment result shows that the YIQ model has better visual effect. |
