摘　　要：多图层无缝融合技术是三维视景仿真中的难点,无缝融合中要求对多个视景图层的融合点进行有效平滑,达到图层深度嵌入的目的。传统的三维飞控图层无缝融合方法采用基于RGB颜色模糊调配与像素点函数内插方法实现,以高阶奇次曲线拟合为目标函数,内插形成图层融合过渡带,此方法对于图层差异较小的融合有较好效果,当图层差异较大时,效果不佳。提出一种基于最大子图序列平滑的三维飞控图层无缝融合技术,对不同图层采用快闪波门预测,扣取图层的最大子图序列,然后将融合图层的最大子图序列放入平滑器进行平滑,采用序列平滑校正方法,对偏离平滑曲线的点进行校正,形成无缝图层融合平滑输出。采用实际三维飞控视景仿真图层进行实验,结果显示,采用该方法,图层融合效果明显优于传统方法,在三维视景仿真的图层融合中具有很好的应用价值。Seamless integration of multi-layer technology is the most difficult thing for three-dimensional visual simulation, the seamless integration points requires for fusion with multiple visual layers effectively smooth, reaching the depth of the layer embedded purposes. In the traditional three-dimensional visual layer fusion method, the fuzzy RGB color pixel inter-polation function method is used,the high-order odd curve fitting is taken as the objective function to deploy and achieve the edge of the center pixel fusion, this method has good effect for a layer of smaller differences, but when the layers are quite different, the results is poor. A three-dimensional flight control visual layers seamless fusion technology based on maximum sub-graph sequence smooth method is proposed, the maximum sub-graph sequence of layers is deducted, the fu-sion sequences is transferred into maximum sub-graph smoothers, the flash wave of door forecast is used in different layers, the smoothing correction method is used for a sequence of smooth curves deviate from the point of correction, and the seam-less smooth result is output. The effective three-dimensional visual simulation layer of flight is taken as experiment, and the results show that with the proposed method, the layer fusion result is better than traditional methods, it has good applica-tion value in the integration layer for the three-dimensional visual simulation.
