摘要
在红外图像特征提取的基础上,提出了一种基于单幅红外图像自动识别并重构标准几何体的方法,即采用红外目标图像上关键点的几何特性对红外目标进行自动分类;利用空间直角变换以获得目标的关键参数;最后实现了红外目标图像的标准几何体的三维模型重构,为复杂红外目标的自动重构打下基础。
A new method in which a 3D reconstruction with single infrared image is carried out through identifying the types of standard geometrical solids automatically is proposed. The edge features based on the temperatures of solids are extracted. Then the geometrical characteristics of key points in the edge features are used to identify the sorts of standard geometrical solids. The 3D standard geometrical models are reconstructed by the key parameters of solids, which are obtained by orthogonal coordinates transform. The 3D reconstruction of standard geometrical solids is the base of reconstruction of complicated solids.
