perceptionmetrics 3.0.1

Tools for evaluating segmentation and object detection models

PerceptionMetrics

Unified evaluation for perception models

Project webpage here

⚠️ PerceptionMetrics was previously known as DetectionMetrics. The original website referenced in our Sensors paper is still available here

PerceptionMetrics is a toolkit designed to unify and streamline the evaluation of object detection and segmentation models across different sensor modalities, frameworks, and datasets. It offers multiple interfaces including a GUI for interactive analysis, a CLI for batch evaluation, and a Python library for seamless integration into your codebase. The toolkit provides consistent abstractions for models, datasets, and metrics, enabling fair, reproducible comparisons across heterogeneous perception systems.

What's supported in PerceptionMetrics

Task	Modality	Datasets	Framework
Segmentation	Image	RELLIS-3D, GOOSE, RUGD, WildScenes, custom GAIA format	PyTorch, Tensorflow
	LiDAR	RELLIS-3D, GOOSE, WildScenes, custom GAIA format	PyTorch (tested with Open3D-ML, mmdetection3d, SphereFormer, and LSK3DNet models)
Object detection	Image	COCO, YOLO	PyTorch (tested with torchvision and torchscript-exported YOLO models)

More details about the specific metrics and input/output formats required fow each framework are provided in the Compatibility section in our webpage.

Installation

In the near future, PerceptionMetrics is planned to be deployed in PyPI. In the meantime, you can clone our repo and build the package locally using either venv or Poetry.

Using venv

Create your virtual environment:

python3 -m venv .venv

Activate your environment and install as pip package:

source .venv/bin/activate
pip install -e .

Using Poetry

Install Poetry (if not done before):

python3 -m pip install --user pipx
pipx install poetry

Install dependencies and activate poetry environment (you can get out of the Poetry shell by running exit):

poetry install
eval $(poetry env activate)

Common

Install your deep learning framework of preference in your environment. We have tested:

• CUDA Version: 12.6
• torch==2.4.1 and torchvision==0.19.1.
• torch==2.2.2 and torchvision==0.17.2.
• tensorflow==2.17.1
• tensorflow==2.16.1

If you are using LiDAR, Open3D currently requires torch==2.2*.

Additional environments

Some LiDAR segmentation models, such as SphereFormer and LSK3DNet, require a dedicated installation workflow. Refer to additional_envs/INSTRUCTIONS.md for detailed setup instructions.

Usage

PerceptionMetrics can be used in three ways: through the interactive GUI (detection only), as a Python library, or via the command-line interface (segmentation and detection).

Interactive GUI

The easiest way to get started with PerceptionMetrics is through the GUI (detection tasks only):

# From the project root directory
streamlit run app.py

The GUI provides:

• Dataset Viewer: Browse and visualize your datasets
• Inference: Run real-time inference on images
• Evaluator: Perform comprehensive model evaluation

For detailed GUI documentation, see our GUI guide.

Library

🧑‍🏫️ Image Detection Tutorial

🧑‍🏫️ Image Detection Tutorial (YOLO)

You can check the examples directory for further inspiration. If you are using poetry, you can run the scripts provided either by activating the created environment using poetry shell or directly running poetry run python examples/<some_python_script.py>.

Command-line interface

PerceptionMetrics provides a CLI with two commands, pm_evaluate and pm_batch. Thanks to the configuration in the pyproject.toml file, we can simply run poetry install from the root directory and use them without explicitly invoking the Python files. More details are provided in PerceptionMetrics website.

Example Usage

Segmentation:

pm_evaluate segmentation image --model_format torch --model /path/to/model.pt --model_ontology /path/to/ontology.json --model_cfg /path/to/cfg.json --dataset_format rellis3d --dataset_dir /path/to/dataset --dataset_ontology /path/to/ontology.json --out_fname /path/to/results.csv

Detection:

pm_evaluate detection image --model_format torch --model /path/to/model.pt --model_ontology /path/to/ontology.json --model_cfg /path/to/cfg.json --dataset_format coco --dataset_dir /path/to/coco/dataset --out_fname /path/to/results.csv

DetectionMetrics

Our previous release, DetectionMetrics, introduced a versatile suite focused on object detection, supporting cross-framework evaluation and analysis. Cite our work if you use it in your research!
