Quick Start Guide: Raspberry Pi with Ultralytics YOLO11#

This comprehensive guide provides a detailed walkthrough for deploying Ultralytics YOLO11 on Raspberry Pi devices. Additionally, it showcases performance benchmarks to demonstrate the capabilities of YOLO11 on these small and powerful devices.

Watch: Raspberry Pi 5 updates and improvements.

!!! note

This guide has been tested with Raspberry Pi 4 and Raspberry Pi 5 running the latest [Raspberry Pi OS Bookworm (Debian 12)](https://www.raspberrypi.com/software/operating-systems/). Using this guide for older Raspberry Pi devices such as the Raspberry Pi 3 is expected to work as long as the same Raspberry Pi OS Bookworm is installed.

What is Raspberry Pi?#

Raspberry Pi is a small, affordable, single-board computer. It has become popular for a wide range of projects and applications, from hobbyist home automation to industrial uses. Raspberry Pi boards are capable of running a variety of operating systems, and they offer GPIO (General Purpose Input/Output) pins that allow for easy integration with sensors, actuators, and other hardware components. They come in different models with varying specifications, but they all share the same basic design philosophy of being low-cost, compact, and versatile.

What is Raspberry Pi OS?#

Raspberry Pi OS (formerly known as Raspbian) is a Unix-like operating system based on the Debian GNU/Linux distribution for the Raspberry Pi family of compact single-board computers distributed by the Raspberry Pi Foundation. Raspberry Pi OS is highly optimized for the Raspberry Pi with ARM CPUs and uses a modified LXDE desktop environment with the Openbox stacking window manager. Raspberry Pi OS is under active development, with an emphasis on improving the stability and performance of as many Debian packages as possible on Raspberry Pi.

Flash Raspberry Pi OS to Raspberry Pi#

The first thing to do after getting your hands on a Raspberry Pi is to flash a micro-SD card with Raspberry Pi OS, insert into the device and boot into the OS. Follow along with detailed Getting Started Documentation by Raspberry Pi to prepare your device for first use.

Set Up Ultralytics#

There are two ways of setting up Ultralytics package on Raspberry Pi to build your next Computer Vision project. You can use either of them.

Start with Docker
Start without Docker

Start with Docker#

The fastest way to get started with Ultralytics YOLO11 on Raspberry Pi is to run with pre-built docker image for Raspberry Pi.

Execute the below command to pull the Docker container and run on Raspberry Pi. This is based on arm64v8/debian docker image which contains Debian 12 (Bookworm) in a Python3 environment.

t=ultralytics/ultralytics:latest-arm64 && sudo docker pull $t && sudo docker run -it --ipc=host $t

After this is done, skip to Use NCNN on Raspberry Pi section.

Start without Docker#

Install Ultralytics Package#

Here we will install Ultralytics package on the Raspberry Pi with optional dependencies so that we can export the PyTorch models to other different formats.

Update packages list, install pip and upgrade to latest

sudo apt update
sudo apt install python3-pip -y
pip install -U pip

Install ultralytics pip package with optional dependencies
```
pip install ultralytics[export]
```
Reboot the device
```
sudo reboot
```

Use NCNN on Raspberry Pi#

Out of all the model export formats supported by Ultralytics, NCNN delivers the best inference performance when working with Raspberry Pi devices because NCNN is highly optimized for mobile/ embedded platforms (such as ARM architecture). Therefor our recommendation is to use NCNN with Raspberry Pi.

Convert Model to NCNN and Run Inference#

The YOLO11n model in PyTorch format is converted to NCNN to run inference with the exported model.

!!! example

=== "Python"

    ```python
    from ultralytics import YOLO

    # Load a YOLO11n PyTorch model
    model = YOLO("yolo11n.pt")

    # Export the model to NCNN format
    model.export(format="ncnn")  # creates 'yolo11n_ncnn_model'

    # Load the exported NCNN model
    ncnn_model = YOLO("yolo11n_ncnn_model")

    # Run inference
    results = ncnn_model("https://ultralytics.com/images/bus.jpg")
    ```

=== "CLI"

    ```bash
    # Export a YOLO11n PyTorch model to NCNN format
    yolo export model=yolo11n.pt format=ncnn  # creates 'yolo11n_ncnn_model'

    # Run inference with the exported model
    yolo predict model='yolo11n_ncnn_model' source='https://ultralytics.com/images/bus.jpg'
    ```

!!! tip

For more details about supported export options, visit the [Ultralytics documentation page on deployment options](https://docs.ultralytics.com/guides/model-deployment-options/).

Raspberry Pi 5 YOLO11 Benchmarks#

YOLO11 benchmarks were run by the Ultralytics team on nine different model formats measuring speed and accuracy: PyTorch, TorchScript, ONNX, OpenVINO, TF SavedModel, TF GraphDef, TF Lite, PaddlePaddle, NCNN. Benchmarks were run on a Raspberry Pi 5 at FP32 precision with default input image size of 640.

Comparison Chart#

We have only included benchmarks for YOLO11n and YOLO11s models because other models sizes are too big to run on the Raspberry Pis and does not offer decent performance.

Detailed Comparison Table#

The below table represents the benchmark results for two different models (YOLO11n, YOLO11s) across nine different formats (PyTorch, TorchScript, ONNX, OpenVINO, TF SavedModel, TF GraphDef, TF Lite, PaddlePaddle, NCNN), running on a Raspberry Pi 5, giving us the status, size, mAP50-95(B) metric, and inference time for each combination.

Reproduce Our Results#

To reproduce the above Ultralytics benchmarks on all export formats, run this code:

!!! example

=== "Python"

    ```python
    from ultralytics import YOLO

    # Load a YOLO11n PyTorch model
    model = YOLO("yolo11n.pt")

    # Benchmark YOLO11n speed and accuracy on the COCO8 dataset for all all export formats
    results = model.benchmarks(data="coco8.yaml", imgsz=640)
    ```

=== "CLI"

    ```bash
    # Benchmark YOLO11n speed and accuracy on the COCO8 dataset for all all export formats
    yolo benchmark model=yolo11n.pt data=coco8.yaml imgsz=640
    ```

Note that benchmarking results might vary based on the exact hardware and software configuration of a system, as well as the current workload of the system at the time the benchmarks are run. For the most reliable results use a dataset with a large number of images, i.e. `data='coco8.yaml' (4 val images), or `data='coco.yaml'` (5000 val images).

Use Raspberry Pi Camera#

When using Raspberry Pi for Computer Vision projects, it can be essentially to grab real-time video feeds to perform inference. The onboard MIPI CSI connector on the Raspberry Pi allows you to connect official Raspberry PI camera modules. In this guide, we have used a Raspberry Pi Camera Module 3 to grab the video feeds and perform inference using YOLO11 models.

!!! tip

Learn more about the [different camera modules offered by Raspberry Pi](https://www.raspberrypi.com/documentation/accessories/camera.html) and also [how to get started with the Raspberry Pi camera modules](https://www.raspberrypi.com/documentation/computers/camera_software.html#introducing-the-raspberry-pi-cameras).

!!! note

Raspberry Pi 5 uses smaller CSI connectors than the Raspberry Pi 4 (15-pin vs 22-pin), so you will need a [15-pin to 22pin adapter cable](https://www.raspberrypi.com/products/camera-cable/) to connect to a Raspberry Pi Camera.

Test the Camera#

Execute the following command after connecting the camera to the Raspberry Pi. You should see a live video feed from the camera for about 5 seconds.

rpicam-hello

Inference with Camera#

There are 2 methods of using the Raspberry Pi Camera to inference YOLO11 models.

!!! usage

=== "Method 1"

    We can use `picamera2`which comes pre-installed with Raspberry Pi OS to access the camera and inference YOLO11 models.

    !!! example

        === "Python"

            ```python
            import cv2
            from picamera2 import Picamera2

            from ultralytics import YOLO

            # Initialize the Picamera2
            picam2 = Picamera2()
            picam2.preview_configuration.main.size = (1280, 720)
            picam2.preview_configuration.main.format = "RGB888"
            picam2.preview_configuration.align()
            picam2.configure("preview")
            picam2.start()

            # Load the YOLO11 model
            model = YOLO("yolo11n.pt")

            while True:
                # Capture frame-by-frame
                frame = picam2.capture_array()

                # Run YOLO11 inference on the frame
                results = model(frame)

                # Visualize the results on the frame
                annotated_frame = results[0].plot()

                # Display the resulting frame
                cv2.imshow("Camera", annotated_frame)

                # Break the loop if 'q' is pressed
                if cv2.waitKey(1) == ord("q"):
                    break

            # Release resources and close windows
            cv2.destroyAllWindows()
            ```

=== "Method 2"

    We need to initiate a TCP stream with `rpicam-vid` from the connected camera so that we can use this stream URL as an input when we are inferencing later. Execute the following command to start the TCP stream.

    ```bash
    rpicam-vid -n -t 0 --inline --listen -o tcp://127.0.0.1:8888
    ```

    Learn more about [`rpicam-vid` usage on official Raspberry Pi documentation](https://www.raspberrypi.com/documentation/computers/camera_software.html#rpicam-vid)

    !!! example

        === "Python"

            ```python
            from ultralytics import YOLO

            # Load a YOLO11n PyTorch model
            model = YOLO("yolo11n.pt")

            # Run inference
            results = model("tcp://127.0.0.1:8888")
            ```

        === "CLI"

            ```bash
            yolo predict model=yolo11n.pt source="tcp://127.0.0.1:8888"
            ```

Best Practices when using Raspberry Pi#

There are a couple of best practices to follow in order to enable maximum performance on Raspberry Pis running YOLO11.

Use an SSD

When using Raspberry Pi for 24x7 continued usage, it is recommended to use an SSD for the system because an SD card will not be able to withstand continuous writes and might get broken. With the onboard PCIe connector on the Raspberry Pi 5, now you can connect SSDs using an adapter such as the NVMe Base for Raspberry Pi 5.
Flash without GUI

When flashing Raspberry Pi OS, you can choose to not install the Desktop environment (Raspberry Pi OS Lite) and this can save a bit of RAM on the device, leaving more space for computer vision processing.
