Abstract: The application of tilt photogrammetry in the construction of digital city is introduced in this paper.In view of the occlusion problem of texture map in the current 3D reconstruction process based on oblique photogrammetry,the geometric principle of texture occlusion is explored in detail,and the high-altitude tilt photography of joint fixed-wing aircraft is proposed to design the unobstructed image optimization algorithm for the 3D model of the building,by which the high-precision unshielded texture automatic map can be realized and verified through experiments.

Key words: multi-source image fusion, 3D reconstruction of buildings, unobstructed texture acquisition
