open3d.ml.torch.datasets.Waymo#
- class open3d.ml.torch.datasets.Waymo(dataset_path, name='Waymo', cache_dir='./logs/cache', use_cache=False, **kwargs)#
This class is used to create a dataset based on the Waymo 3D dataset, and used in object detection, visualizer, training, or testing.
The Waymo 3D dataset is best suited for autonomous driving applications.
- __init__(dataset_path, name='Waymo', cache_dir='./logs/cache', use_cache=False, **kwargs)#
Initialize the function by passing the dataset and other details.
- Parameters:
dataset_path – The path to the dataset to use.
name – The name of the dataset (Waymo in this case).
cache_dir – The directory where the cache is stored.
use_cache – Indicates if the dataset should be cached.
- Returns:
The corresponding class.
- Return type:
class
- static get_label_to_names()#
Returns a label to names dictionary object.
- Returns:
A dict where keys are label numbers and values are the corresponding names.
- get_split(split)#
Returns a dataset split.
- Parameters:
split – A string identifying the dataset split that is usually one of
'training' –
'test' –
'validation' –
'all'. (or) –
- Returns:
A dataset split object providing the requested subset of the data.
- get_split_list(split)#
Returns the list of data splits available.
- Parameters:
split – A string identifying the dataset split that is usually one of
'training' –
'test' –
'validation' –
'all'. (or) –
- Returns:
A dataset split object providing the requested subset of the data.
- Raises:
ValueError – Indicates that the split name passed is incorrect. The
split name should be one of 'training', 'test', 'validation', or –
'all'. –
- is_tested()#
Checks if a datum in the dataset has been tested.
- Parameters:
attr – The attribute that needs to be checked.
- Returns:
- If the datum attribute is tested, then return the path where the
attribute is stored; else, returns false.
- static read_calib(path)#
Reads calibiration for the dataset. You can use them to compare modeled results to observed results.
- Returns:
The camera and the camera image used in calibration.
- static read_label(path, calib)#
Reads labels of bounding boxes.
- Parameters:
path – The path to the label file.
calib – Calibration as returned by read_calib().
- Returns:
The data objects with bounding boxes information.
- static read_lidar(path)#
Reads lidar data from the path provided.
- Returns:
- pointcloud data with shape [N, 6], where
the format is xyzRGB.
- Return type:
pc
- save_test_result(attr)#
Saves the output of a model.
- Parameters:
results – The output of a model for the datum associated with the attribute passed.
attr – The attributes that correspond to the outputs passed in results.
