Function mindspore::dataset::KITTI
Defined in File datasets.h
Function Documentation
Function to create a KITTIDataset.
Note
When usage is ‘train’, the generated dataset has multi-columns, ‘image’, ‘label’, ‘truncated’, ‘occluded’, ‘alpha’, ‘bbox’, ‘dimensions’, ‘location’, ‘rotation_y’; When usage is ‘test’, the generated dataset has one column ‘image’.
- Parameters
dataset_dir – [in] Path to the root directory that contains the dataset.
usage – [in] The type of data file to read (default = “train”).
decode – [in] Decode the images after reading (default = false).
sampler – [in] Sampler object used to choose samples from the dataset. If sampler is not given, a
RandomSampler
will be used to randomly iterate the entire dataset (default = RandomSampler()).cache – [in] Tensor cache to use (default=nullptr, which means no cache is used).
- Returns
Shared pointer to the current Dataset.
Example/* Define dataset path and MindData object */ std::string folder_path = "/path/to/kitti_dataset_directory"; std::shared_ptr<Dataset> ds = KITTI(folder_path); /* Create iterator to read dataset */ std::shared_ptr<Iterator> iter = ds->CreateIterator(); std::unordered_map<std::string, mindspore::MSTensor> row; iter->GetNextRow(&row); /* Note: In KITTI dataset, each dictionary has key "image" */ auto image = row["image"];
