摘要
本文首先解释T-共线方程的概念,提出了基于T-共线方程进行三维配准的准则和数学模型,以及两共轭影像在三维空间进行配准和三维重建的计算方法。可视化将人类对现实世界认识的准则:感觉-思维-认知,应用于对数据世界的认识,因此配准、融合和立体视觉重建,有助于对地球影像的理解和解译。本文以三个案例的卫星和航空摄影地形测量数据,基于T-共线方程,对摄影地形测量数据的配准、融合和可视化,进行了原理性试验。
At first,the concept of T-collinear equation is explained in this paper.Based on T-collinear equation the rules and mathematic model for 3D registration and 3D reconstruction are put forward.The computation method for 3D registration and 3D reconstruction with two conjugate images is studied.The rule “Sensation-Thinking-Recognition” with which human being recognize the reality,is applied to visualization for understanding the Datum world,So the registration,fusion and stereoscopic vision reconstruction could be useful for Geo image interpretation。In three cases,Based on T-collinear equation the satellite and aerial phototopographic data are used to 3D registration,fusion and visualization test.
