Research on Rapidly Reconstructing Texture for Facades in 3D City Modeling

Rapidly reconstructing texture for building is now urgent and actual "bottle-neck" problem in three Dimensional City Modeling(3DCM).In this paper,we not only outline essential problems and propose reasonable solutions toward rapid texture reconstruction but also make specification on how to select image resource for texture,which way to take picture and what kind of software system should be set up.In addition,key algorithmics like Determining camera parameters,Matching building to its projection in images and so on,are detailed discussed and implemented.Taking two kind of image,one is close-image taken by digital camera and another is image sequences captured by digital video on helicopter,as texture resource,we design and implment two software system to make experiment and gain the encouraging result.
