你们好!感谢你们的杰出工作!我想请问你们的距离场文件是如何获取的?

我在utils/dexnet/grasping/meshpy/sdf_file.py下看到SdfFile类的write方法没有实现;通过blender建模时没有找到“符号距离场”相关文件的导出方法;在网上有查到使用gazebo导出.sdf文件的方法,但是与你们数据集中提供的.sdf文件并不是同类的内容。

我目前有以下进展:

  1. 符号距离场文件(.sdf)可以使用dex-net中的代码生成。可以搜索dex-net搭建环境参考相关实现(需要使用SDF-Gen)
  2. 我尝试复现了dexnet中的SDF_GEN,导入了如001-饼干盒、002-罐头等简单的物品模型,这些模型生成的.sdf文件与数据集中的.sdf文件相同;但导入复杂模型如026-一字螺丝刀头、071-三阶魔方时,生成的.sdf文件与数据集中的.sdf文件不同。

作者团队提供工具(邀请制),工具包含生成sdf脚本。有需要的各位可以前去 graspnet/graspnet-baseline#33 申请
