Trajectory Annotation

[wzcai99]

Hi, thank you for the great work on UrbanNav dataset. I am trying to use the dataset and after downloading from the Huggingface, I cannot find the trajectory annotations, all the data saved in the json file are the instance descriptions. Am I missing some important data processing steps?

Hi, the trajectory annotations are stored in the .txt files using the TUM format. We will update the README to clarify this data structure soon.

Hi, thanks for your reply. But after I download the data_samples.tar.gz from https://huggingface.co/datasets/Vigar001/UrbanNav/tree/main, I can only get some images, a .json file and a pkl file.

Hi, the data_samples.tar.gz file is just a small sample pack meant for debugging; to get the complete raw trajectories and instruction labels, you'll need to download the annos.tar.gz.

But after I downloaded the anno.tar.gz and unzip it, I can only get txt files with raw trajectories without instruction labels. And here are some of the downloaded txt files.
