纹理映射作为三维重建的重要步骤,直接关系到生成模型的视觉效果。传统的纹理映射方法通常使用简单的混合方法来获取表面纹理。通过将模型表面投影到每个纹理图像上来获取相应的纹理区域,然后将它们混合在一起以获取表面纹理。然而,由于相机位姿的不准确性,纹理映射结果存在明显的模糊和鬼影等问题。此外,在高光环境下获取的纹理图像很容易包含高光区域,最终导致纹理颜色的丢失,降低纹理的真实性。为了解决这些问题,提出了一种无缝纹理映射方法,可以有效消除高光反射。通过衡量纹理图像的质量,为每个模型表面选择最佳的纹理图像,并利用色度一致性约束优化的相机位姿以消除明显的纹理错位。针对高光问题,提出了一个高光处理模块,使用多视图图像信息并基于双色反射模型定位和处理高光纹理。最后,对纹理图进行纹理颜色一致性调整,以处理纹理之间的颜色差异。实验结果表明,与现有方法相比,提出的算法可以有效消除高光反射的影响,从而获得更好的纹理映射结果。

As an important step of 3D reconstruction,texture mapping is directly related to the visual effect of the generative model.Classical texture mapping methods usually employ a simple blending method to obtain the surface texture.The corresponding texture regions are obtained by projecting the model surface onto each texture image,and then blending them to obtain the surface texture.However,due to the inaccuracy of the camera pose,the texture mapping results exhibit evident problems such as blurriness and ghosting.In addition,the texture images acquired in the high-light environment tend to contain highlight areas,resulting in texture color loss and diminished texture authenticity.To address these issues,a seamless texture mapping method capable of effectively eliminating highlight reflections was proposed.The method selected the best texture image for each model surface by assessing the quality of the texture image,and chromaticity consistency was utilized to constrain the optimized camera pose,eliminating obvious texture misalignments.To address the highlight problem,a highlight processing module was proposed,utilizing multi-view image information and employing a two-color reflection model to identify and process the highlight texture.Finally,adjustments were made to the texture color consistency to tackle color inconsistency between textures.The experimental results demonstrated that the proposed algorithm can obtain superior texture mapping results compared with state-of-the-art methods and effectively eliminate highlight reflections.
