Data Visualization

Hi there! Thank you for your outstanding work! I am trying to generate diagrams of 3D bounding boxes in your paper from the YAML annotation files in the dataset. I have encountered some confusion during the camera projection transformation, which has led to significant issues with the bounding boxes I have drawn. Could you please share your visualization code? Or provide some explanations about the data? Thank you very much!

Hi,

Did you figure out how to do this correctly?
I am facing a similar problem. @XHwind, your response here would be greatly appreciated.

Thanks,

I haven’t resolved the visualization issue yet, which has prevented me from continuing work on this dataset. I tried another dataset, TUMTraf, and was able to visualize the annotated data. I also attempted RCooper, but encountered similar visualization issues.

According to RoCo-Sim, visualization problems with roadside device annotations are common in V2X datasets. Its author proposed some correction methods, and I’m looking forward to the release of their code.

If you have any solutions for visualizing V2X-Real, please feel free to contact me. Thank you very much!

Hi there, thank you for using our dataset! I think the issue that you're facing is because of the transformation matrix. Please check out our dataset tool repo for getting the correct transformation: https://github.com/zhz03/dataset_tool

You can also find some examples there: https://github.com/zhz03/dataset_tool/blob/main/data_examples/v2x-real/vehicle_1/output/000030_cam1_bbx_20251110_153609.jpg

Please let me know if there are any questions regarding our code!
