如何准备数据集？

[yangfengzzz]

请问我在BODex的论文中看到，通过Blender渲染Realsense D435的数据集，也就是这里提供下载的几个数据集。请问能否自己合成这些数据集，点云数据是如何得到的？

BODex does not use Blender. Some of our previous work (e.g., DREDS, HOTrack) leveraged Blender to simulate realistic point cloud noise in order to reduce the sim-to-real gap.

However, since this is not the focus of our current work—and given that Blender rendering is relatively slow—we directly generate synthetic point clouds using this tool, without explicitly addressing the sim-to-real gap.
