基于 IR-SFS 算法空间目标红外影像3D重建
3 D reconstruction of space target IR image based on IR-SFS algorithm
摘要
Abstract
In this paper, a new 3D surface reconstruction algorithm named IR-SFS(shape from shading for in-frared images) for infrared images of space targets is proposed based on the traditional single image SFS ( shape from shading) algorithm, in which both external light source and self-radiation of infrared objects are consid-ered.Firstly, the traditional SFS algorithm is described and the features of IR imaging of space targets are then analyzed to build the IR-SFS radiation equation followed by simulation study .Using temperature estimation to get the IR residual gray image , 3 D reconstruction models are achieved on the synthetic infrared images of he-mi-sphere , hemi-cylinder satellite and the real infrared image of USA STS 107 ( Space Transportation System Program 107 ) as the experimental targets .The experiment results show that higher peak signal to noise ratio ( PSNR) and better visibility at the top of the space shuttle door , the tail, the cabin and the square equipment in the cabin of STS107 can be obtained by using the proposed 3D reconstruction algorithm with optimized pa-rameters.The overall performance is significantly improved compared to the original SFS algorithm .关键词
