摘要

提出了一种基于高/多光谱图像的空天一体融合仿真方法。以航空高光谱数据为基础，根据航天多光谱遥感相关参数，通过空天一体光谱维变换、尺度空间变换、辐射强度变换、混合像素变换和噪声变换将航空高光谱图像中的地物目标进行空天一体映射到航天多光谱图像中，得到特定地物目标的航天多光谱融合模拟仿真图像。仿真实验表明该方法简便易行，有效地减少了地物目标的三维建模和探测器响应建模的巨大工作量，较好地实现了对特定地物目标航天多光谱图像的模拟，开拓了遥感图像仿真模拟方法的新领域，具有重要的研究和应用价值。%A simulation method by air and space integrated fusion based on hyper-/multispectral imagery is proposed. The transformations of spectra, scale-space, radiative intensity, mixed pixel, noise are adopted in the simulation method on the basis of aviatic multispectral imagery according to parameters of space multispectral imagery, and certain ground objects in the aviatic hyperspectral imagery are mapped into the space multispectral imagery to obtain simulative space multispectral imagery for these ground objects through the simulation method. Experimental results demonstrate that the simulation method is effective and easy to implement; the heavy workload on model establishment of three-dimensional scene and sensor response is reduced in this simulation method;it is successful for the method to simulate space multispectral imagery of certain ground objects. A new domain on simulation method of remote sensing imagery is developed. This simulation method is valuable in research and application.
