Abstract: Thc local photogrammetry texture mapping using casual images is a new 3D model texture mapping method, but there is texture distortion from lack of local texture. A compensation method of texture mapping was presented. On the basis of the local photogrammetry and constraint parameters texture mapping method, according to the relationship between the model and casual images, the area of texture missing is determined. I}he minimum rigid-body dynamics iner- tia determination method and mirror image method are utilized to search for the symmetry plane within the scope of model mapping. I}he texture information of the symmetric points is got to implement compensation of texture mapping for the area of texture missing. Experimental results show that,for the local symmetrical 3D modcl,the area of texture missing is complemented,and the texture stretching distortion is eliminated.
