# OpenDV-YouTube |
|
|
|
This is the dataset repository of `OpenDV-YouTube` language annotations, including `context` and `command`. For more details, please refer to <a href="https://arxiv.org/abs/2403.09630" target="_blank">GenAD</a> project and <a href="https://github.com/OpenDriveLab/DriveAGI#opendv-youtube" target="_blank">OpenDV-YouTube</a>. |
|
|
|
## Usage |
|
|
|
To use the annotations, you need to first download and prepare the data as instructed in <a href="https://github.com/OpenDriveLab/DriveAGI/tree/main/opendv" target="_blank">OpenDV-YouTube</a>. **Note that we recommend to process the dataset in `Linux` environment since `Windows` may have issues with the file paths.** |
|
|
|
You can use the following code to load in annotations respectively. |
|
|
|
```python |
|
import json |
|
|
|
# for train |
|
full_annos = [] |
|
for split_id in range(10): |
|
split = json.load(open("10hz_YouTube_train_split{}.json".format(str(split_id)), "r")) |
|
full_annos.extend(split) |
|
|
|
# for val |
|
val_annos = json.load(open("10hz_YouTube_val.json", "r")) |
|
``` |
|
|
|
Annotations will be loaded in `full_annos` as a list where each element contains annotations for one video clip. All elements in the list are dictionaries of the following structure. |
|
|
|
```python |
|
{ |
|
"cmd": <int> -- command, i.e. the command of the ego vehicle in the video clip. |
|
"blip": <str> -- context, i.e. the BLIP description of the center frame in the video clip. |
|
"folder": <str> -- the relative path from the processed OpenDV-YouTube dataset root to the image folder of the video clip. |
|
"first_frame": <str> -- the filename of the first frame in the clip. Note that this file is included in the video clip. |
|
"last_frame": <str> -- the filename of the last frame in the clip. Note that this file is included in the video clip. |
|
} |
|
``` |
|
|
|
The command, *i.e.* the `cmd` field, can be converted to natural language using the `map_category_to_caption` function. You may refer to [cmd2caption.py](https://github.com/OpenDriveLab/DriveAGI/blob/main/opendv/utils/cmd2caption.py#L158) for details. |
|
|
|
The context, *i.e.* the `blip` field, is the description of the **center frame** in the video generated by `BLIP2`. |
