Three-dimensional reconstruction for high-resolution satellite remote sensing image based on RFM

随着高分辨率卫星遥感成像技术的快速发展,基于卫星影像的三维重建技术研究已成为当前国内外研究的热点,但由于种种因素的制约,实现自动化、高精度的三维重建仍然存在很大困难。鉴于此,提出一种基于同源高分辨率卫星影像的三维信息提取方法,其步骤包括利用影像匹配技术获取同名点,通过影像同名点解算像对间几何转换模型,最终基于有理函数模型获取地物点的三维坐标。结果表明,利用文中方法可以实现影像的三维重建,精度上能够满足一定的生产需求。

With the rapid development of high-resolution satellite remote sensing imaging technique, 3Dreconstruction based on satellite image has become a focus of research, But it＇s difficult to perform anautomatic and high-precision 3D construction model due to various factors. A method for the 3Dinformation extraction based on homologous high-resolution satellite irnages is given. First, getting thecorresponding points by matching technology. Second building transform model between image pairs.Finally achieving the spatial coordinates based on the rational functionl model. The experimental resultshows that the method proposed can achieve a 3D image reconstruction which can meet the actual demandsfor its precision.
