Laser scanning is an effective way to acquire geometry data of the cultural heritage with complex architecture. After
generating the 3D model of the object, it's difficult to do the exactly texture mapping for the real object. we take effort to
create seamless texture maps for a virtual heritage of arbitrary topology. Texture detail is acquired directly from the real
object in a light condition as uniform as we can make. After preprocessing, images are then registered on the 3D mesh
by a semi-automatic way. Then we divide the mesh into mesh patches overlapped with each other according to the valid
texture area of each image. An optimal correspondence between mesh patches and sections of the acquired images is
built. Then, a smoothing approach is proposed to erase the seam between different images that map on adjacent mesh
patches, based on texture blending. The obtained result with a Buddha of Dunhuang Mogao Grottoes is presented and
discussed.
