Accurate texture mapping is a key factor for reconstructing visually realistic models. After basic theory of texture mapping is introduced

two practical issues are discussed for 3D reconstruction based on 3D laser scanner. An algorithm of model reconstruction based on its texture and an algorithm of lighting consistency recovery of texture images are proposed to deal with the inconsistency of images in space and lighting. Experiments with real outdoor data prove the effectiveness of these algorithms

which will lay a technological foundation for improving visual reality of 3D reconstruction of outdoor objects in large scale.
