about the classification part about sg_pr

[lxh990620]

I would like to know the algorism of genrating the semantic graph.
Could i consider the .json format data as the semantic graph?
According to Raw input>semantic segmentation>instance segmentation>semantic graph.

Thanks a lot.

Hi! Thanks for your interest in our work!

1. For visualizing the 3D semantic graph, you can simply draw the nodes with colour according to their semantic labels and 3D positions, which are stored in the .json files. We created the visualization with ROS Rviz.
2. For the classification details, you can find here that we map the original semantic KITTI labels to ours.
3. Yeah, you can consider .json files as semantic graphs. Each .json represents a semantic graph for the scene and the index is the file name.

Hope it helps you. Please let me know if anything unclear. Thank you!
