近年来,Deep Learning(以下简称DL)在计算机视觉上的应用在2D图像方面几乎已经无孔不入。不论是检测,分割还是分类,DL已经成为了图像处理的主要方法。然而目前 DL在三维重建方面的应用还比较少,例如在Image-based 3D Reconstruction方面,传统的SFM方法仍然是公认的较为优秀的主流方法,而DL在这方面的应用还不成熟。今天给...
Surface Reconstruction Geometric Regularization Flattening 3D高斯:受2D高斯散斑(2DGS)的启发,我们的目标是将3D椭球体压平成2D圆盘,使优化的高斯更好地符合物体表面,并实现高质量的表面重建。3DGS的尺度s=(s1,s2,s3)定义了椭球体沿三个正交轴的大小。最小化沿最短轴的比例有效地将3D椭球体转换为2D磁盘。缩放正...
