Data Format

The data includes a training set, a validation set, comprising 13,204 categories. The training set consists of 183,354 images, while the validation set has 29,821 images. The data organization is:

Annotation Files

Train/Val

The annotation files are provided in dictionary format and contain the keywords "images," "categories," and "annotations."

images : store a list containing image information, where each element is a dictionary representing an image.

    file_name            # The relative image path, eg. images/n07745046/21_371_29405651261_633d076053_c.jpg.
    height               # The height of the image
    width                # The width of the image
    id                   # Unique identifier of the image.

categories : store a list containing category information, where each element is a dictionary representing a category.

    name                 # English name of the category.
    name_zh              # Chinese name of the category.
    cat_info             # The format for the description information of categories is a list.
    cat_info_gpt         # The format for the description information of categories generated by ChatGPT is a list.
    novel                # For open-vocabulary detection, indicate whether the current category belongs to the 'novel' category.
    id                   # Unique identifier of the category.

annotations : store a list containing annotation information, where each element is a dictionary representing a bounding box annotation.

    image_id             # The unique identifier of the image where the bounding box is located.
    category_id          # The unique identifier of the category corresponding to the bounding box.
    bbox                 # The coordinates of the bounding box, in the format [x, y, w, h], representing the top-left corner coordinates and the width and height of the box.
    iscrowd              # Whether the bounding box is a crowd box.
    area                 # The area of the bounding box

Category Tree

The category tree stores information about dataset category mappings and relationships in dictionary format.

    categoryid2treeid    # Unique identifier of node in the category tree corresponding to the category identifier in dataset
    id2name              # English name corresponding to each node in the category tree
    id2name_zh           # Chinese name corresponding to each node in the category tree
    id2desc              # English description corresponding to each node in the category tree
    id2desc_zh           # Chinese description corresponding to each node in the category tree
    id2synonym_list      # List of synonyms corresponding to each node in the category tree
    id2center_synonym    # Center synonym corresponding to each node in the category tree
    father2child         # All direct child categories corresponding to each node in the category tree
    child2father         # All direct parent categories corresponding to each node in the category tree
    ancestor2descendant  # All descendant nodes corresponding to each node in the category tree
    descendant2ancestor  # All ancestor nodes corresponding to each node in the category tree

Image Download

Run the command to crawl the images. By default, the images will be stored in the './V3Det/' directory.

python v3det_image_download.py

If you want to change the storage location, you can specify the desired folder by adding the option '--output_folder' when executing the script.

python v3det_image_download.py --output_folder our_folder

Category Tree Visualization

Run the command and then select dataset path path/to/V3Det to visualize the category tree.

python v3det_visualize_tree.py

Please refer to the TreeUI Operation Guide for more information.
