文中介绍了一种利用划分地物区域单元和地物特征生成红外热图像的方法。获得地物区域的方法有两种 :一种是针对一定的地面背景 ,借助于可见光图像数据 ,利用图像分割将地面背景按地物类型分为若干局部区域单元并进行单元类型编码 ;另一种直接利用计算机构造出不同的地表区域并编码。然后根据典型地物热模型和地表辐射统计模型 ,分析局部区域内的辐射起伏 ,完成局部区域的纹理处理 ,生成比较逼真的自然地面背景红外图像。
In this paper, a method of generating infrared thermal images using the features and features of the regionalized objects is introduced. There are two ways to get the feature area: one is for a certain ground background, with the help of visible light image data, the use of image segmentation will be ground background according to the type of object is divided into several local unit and cell type coding; the other Directly use computers to construct different surface areas and encode. Then, based on the typical terrain thermal model and surface radiation statistical model, the radiation fluctuation in the local area is analyzed, and the texture processing in the local area is completed to generate a more realistic natural ground background infrared image.
