关于相机w2c矩阵的问题: #7
Comments
万分期待您的解答! |
你好!你使用了blender渲染的数据集,你需要删除https://github.com/TencentARC/InstantMesh/blob/7fe95627cf819748f7830b2b278f302a9d798d17/src/data/objaverse.py#L186 |

您好,在instantmesh的objaverse.py文件中,代码显示加载的是cameras.npz文件中的cam_poses,并且将其作为w2c矩阵。您的渲染数据集的代码好像将cam_poses作为了c2w矩阵,好像存在一点点问题。还有一个问题就是您的代码也提供了w2c矩阵,对应为cam_poses_w2c,我想知道为什么get_3x4_RT_matrix_from_blender()函数中要将旋转和平移都左乘cam_rec,cam_rec将y轴和z轴都转换了方向,为什么要这样做?可以和instantmtesh中对应的上吗?
