针对全景影像难以提供空间度量的问题，提出一种基于双球面投影几何的可量测立体全景模型构建方法。该方法依据球面全景投影关系与多视几何原理，采用对应变换与本质变换求取旋转及平移参数，并推导出双球面核线约束；在此基础上，建立起双球面投影几何的立体全景模型，解决了球面全景的量测问题。实验结果表明，文中方法可使全景影像在真实呈现户外场景的同时，提供满足一定应用需求的量测分析功能。

Stereo vision reconstruction is an unresolved and hot research topic in the fields of computer vision and photogrammetry. The conventional techniques are mainly based on a limited field of view (FOV), which re-sults in the problems of blind areas and insufficient overlapping degrees. Though panorama is able to show a 360-degree field of view, it performs poorly in precision. In this paper, we present an innovative measurement vi-sion system on the strength of binocular spherical panoramas. We proposed a geometric model according to the principles of spherical panorama projection and multi-view geometry. In this model, we adopted the homography transformation and the essential transformation to obtain the parameters of the rotation matrix and the translation vector, which are used to establish binocular spherical projection geometry. The experiment we carried out vali-dated the feasibility of our model, which could be applied to the 3D measurement process.
