Roboflow Universe

Object Detection Segmentation Base Model

What is Roboflow Universe?¶

Roboflow Universe is a community where people share computer vision models and datasets. Over 50,000 models and 250,000 datasets have been shared on Universe, with new models available every day. You can use Autodistill to run object detection and segmentation models hosted on Roboflow Universe.

[!NOTE] Using this project will use Roboflow API calls. You will need a free Roboflow account to use this project. Sign up for a free Roboflow account to get started. Learn more about pricing.

Installation¶

To use models hosted on Roboflow Universe with autodistill, you need to install the following dependency:

pip3 install autodistill-roboflow-universe

Quickstart¶

[!NOTE] Autodistill uses ontology to map model predictions to the expected class labels. For other Autodistill models, the term 'caption' is used when the model accepts prompting or a description for a prediction. When using Roboflow Universe as an Autodistill base model, the 'caption' will be the class name/label that the Universe model will return.

from autodistill_roboflow_universe import RoboflowUniverseModel
from autodistill.detection import CaptionOntology
from autodistill.utils import plot
import cv2

# define an ontology to map class names to our Roboflow model prompt:
# the ontology dictionary has the format {caption: class}
# where caption is the prompt sent to the base model, and class is the label that will
# be saved in the generated annotations

model_configs = [
    ("PROJECT_ID", VERSION_NUMBER)
]

base_model = RoboflowUniverseModel(
    ontology=CaptionOntology(
        {
            "person": "person",
            "forklift": "vehicle"
        }
),
    api_key="ROBOFLOW_API_KEY",
    model_configs=model_configs,
)

# run inference on a single image
result = base_model.predict("image.jpeg")

print(result)

plot(
    image=cv2.imread("image.jpeg"),
    detections=result,
    classes=base_model.ontology.classes(),
)

# label a folder of images
base_model.label("./context_images", extension=".jpeg")

Above, replace:

API_KEY: with your Roboflow API key
PROJECT_NAME: with your Roboflow project ID.
VERSION: with your Roboflow model version.
model_type: with the type of model you want to run. Options are object-detection, classification, or segmentation. This value must be the same as the model type trained on Roboflow Universe.

You can run multiple models on a single image. This is ideal if you need to identify multiple objects using different models hosted on Roboflow Universe. To run multiple models, add the models you want to run in the model_configs list. For example:

model_configs = [
    ("PROJECT_ID", VERSION_NUMBER),
    ("PROJECT_ID", VERSION_NUMBER)
]

All models will be run on every image.
