Abstract
The present invention discloses a method for modeling and registering 3D scene structure based on single image, belonging to the field of virtual reality technology. The method includes calibrating camera through analyzing image line features; analyzing property of plane support relationship by using categorized lines to obtain a preliminary scene structure; optimizing scene structure via interoperation by a small number of users to complete modeling of scene structure for whole image; and finally registering 3D image scene structure, collected by different cameras through line features, into a unified 3D scene, allowing application into modeling of wide-range scene structure. According to the present invention, corresponding information of 3D scene structure can be rapidly obtained through interoperation by a small number of users. In the meantime, the present invention can guarantee modeling integrity of scene structure and effectively reducing 3D modeling cost, making 3D reconstruction of wide-range scene structure easier.
