提出了一种海天目标三维实时红外场景的仿真方法。首先建立了场景的3D物理模型,然后根据黑体辐射理论分别计算出背景与目标的红外辐射特性。考虑到气温对成像的影响,以及探测器分别对3~5μm与8~12μm波段的响应率,根据物体的表观温度对视场内的红外图像进行显示。最后将背景与目标进行融合得到最终的仿真场景。通过提出的方法对海面天空背景的建模与红外仿真以及水面舰艇的建模与红外仿真得到的三维实时红外仿真场景效果逼真与实测图像接近。
提齣瞭一種海天目標三維實時紅外場景的倣真方法。首先建立瞭場景的3D物理模型,然後根據黑體輻射理論分彆計算齣揹景與目標的紅外輻射特性。攷慮到氣溫對成像的影響,以及探測器分彆對3~5μm與8~12μm波段的響應率,根據物體的錶觀溫度對視場內的紅外圖像進行顯示。最後將揹景與目標進行融閤得到最終的倣真場景。通過提齣的方法對海麵天空揹景的建模與紅外倣真以及水麵艦艇的建模與紅外倣真得到的三維實時紅外倣真場景效果逼真與實測圖像接近。

A model to simulate 3D maritime target on the ocean background is introduced. First, a 3D physics model is con- structed. Afterwards, the infrared radiation characters of background and targets are calculated respectively according to the blackbody radiation theory. The influence of atmosphere temperature on the images is calculated in both 3-5μm and 8--12 μm wavebands. The infrared image based on the apparent object temperature is demonstrated. FinaIly, the backgrounds and targets are integrated to create the final simulation scene. The comparison experiment proves that the result of modeling and simulation is realistic and close to the practical images.
