摘　　要：纹理映射研究二维纹理与三维曲面的映射模型,实现三维模型的表面纹理恢复,是实景三维模型重建的最后一步。由于匹配误差的存在,映射模型解算结果也存在相应的误差,造成模型表面纹理贴合效果不佳。本文提出基于TPS的纹理坐标差值校正方法,利用TPS光滑、连续、弹性好的特点,对映射模型进行修正,实现精准高效的纹理贴图。Texture mapping studies the mapping model of 2D texture and 3D surface, which realizes the surface texture restoration of 3D model.It is the last step in reconstruction of the 3D model.Due to the matching error, the corresponding error is found in the calculation result of the mapping model, which results in the poor surface texture of the model.In this paper we present a method correcting the difference of texture coordinate based on TPS, which has the characteristics of smooth, continuous and elastic.It modifies the mapping model, which achieves accurate and efficient texture mapping.
