  • 摘要:针对双目立体视觉重建点云模型与高分辨率纹理图像的融合问题,本文提出了一种新的纹理映射方法。在双目立体视觉系统上增设长焦纹理相机拍摄高分辨率纹理图像,利用高分辨率纹理图像与双目图像的二维特征匹配,以双目图像为桥梁,得到纹理图像与三维点云模型的匹配关系,进而实现高分辨率纹理图像到三维点云模型的映射。同时,针对映射过程中多视纹理图像重叠部分的数据冗余,提出一种引导线点云数据分区方法,有效解决了多视纹理图像重叠部分的映射问题。通过实验验证,所提方法能够方便准确地实现多视纹理图像与双目三维点云模型的纹理映射。在本文实验条件下,三维模型的纹理可分辨原始线宽为0.157 mm的线对,与双目系统直接产生的三维模型相比,其纹理分辨率提高了1倍,验证了所提出的多视高分辨率纹理映射方法的有效性。
