📑 目录

👋 你好

我们是您计算机视觉的核心工具包。 从数据加载到实时区域计数,我们提供构建模块,让您能够专注于围绕模型构建应用程序。🤝

💻 安装

Python>=3.10 环境中通过 Pip 安装 supervision 包。

pip install supervision

在我们的指南中阅读更多关于 conda、mamba 以及从源码安装的内容。

🔥 快速入门

模型

Supervision 被设计为模型无关。只需接入任何分类、检测或分割模型。为了方便起见,我们为 Ultralytics、Transformers、MMDetection 或 Inference 等最流行的库创建了连接器。其他集成,如 rfdetr,已经直接返回 sv.Detections

使用 pip install pillow rfdetr 安装此示例的可选依赖项。

import supervision as sv
from PIL import Image
from rfdetr import RFDETRSmall

image = Image.open("path/to/image.jpg")
model = RFDETRSmall()
detections = model.predict(image, threshold=0.5)

len(detections)
# 5

  • inference

    使用 Inference 需要 Roboflow API KEY

    import supervision as sv
    from PIL import Image
    from inference import get_model
    
    image = Image.open("path/to/image.jpg")
    model = get_model(model_id="rfdetr-small", api_key="ROBOFLOW_API_KEY")
    result = model.infer(image)[0]
    detections = sv.Detections.from_inference(result)
    
    len(detections)
    # 5

标注器

Supervision 提供了大量高度可定制的 标注器,允许您为特定用例组合出完美的可视化效果。

import cv2
import supervision as sv

image = cv2.imread("path/to/image.jpg")
# Assuming detections are obtained from a model
detections = sv.Detections(...)

box_annotator = sv.BoxAnnotator()
annotated_frame = box_annotator.annotate(scene=image.copy(), detections=detections)

Datasets

Supervision 提供了一组 utils,允许你以受支持的格式之一加载、拆分、合并和保存数据集。

import supervision as sv
from roboflow import Roboflow

project = Roboflow().workspace("WORKSPACE_ID").project("PROJECT_ID")
dataset = project.version("PROJECT_VERSION").download("coco")

ds = sv.DetectionDataset.from_coco(
    images_directory_path=f"{dataset.location}/train",
    annotations_path=f"{dataset.location}/train/_annotations.coco.json",
)

path, image, annotation = ds[0]
# loads image on demand

for path, image, annotation in ds:
    # loads image on demand
    pass

  • load

    dataset = sv.DetectionDataset.from_yolo(
        images_directory_path=...,
        annotations_directory_path=...,
        data_yaml_path=...,
    )
    
    dataset = sv.DetectionDataset.from_pascal_voc(
        images_directory_path=...,
        annotations_directory_path=...,
    )
    
    dataset = sv.DetectionDataset.from_coco(
        images_directory_path=...,
        annotations_path=...,
    )
  • 拆分

    train_dataset, test_dataset = dataset.split(split_ratio=0.7)
    test_dataset, valid_dataset = test_dataset.split(split_ratio=0.5)
    
    len(train_dataset), len(test_dataset), len(valid_dataset)
    # (700, 150, 150)
  • 合并

    ds_1 = sv.DetectionDataset(...)
    len(ds_1)
    # 100
    ds_1.classes
    # ['dog', 'person']
    
    ds_2 = sv.DetectionDataset(...)
    len(ds_2)
    # 200
    ds_2.classes
    # ['cat']
    
    ds_merged = sv.DetectionDataset.merge([ds_1, ds_2])
    len(ds_merged)
    # 300
    ds_merged.classes
    # ['cat', 'dog', 'person']
  • 保存

    dataset.as_yolo(
        images_directory_path=...,
        annotations_directory_path=...,
        data_yaml_path=...,
    )
    
    dataset.as_pascal_voc(
        images_directory_path=...,
        annotations_directory_path=...,
    )
    
    dataset.as_coco(
        images_directory_path=...,
        annotations_path=...,
    )
  • 转换

    sv.DetectionDataset.from_yolo(
        images_directory_path=...,
        annotations_directory_path=...,
        data_yaml_path=...,
    ).as_pascal_voc(
        images_directory_path=...,
        annotations_directory_path=...,
