This example demonstrates how to continuously focus on the first detected face. It will determine the distance to the face and adjust the lens position accordingly. The example requires a device with an auto-focus color camera and a stereo camera pair to function properly. The example uses YuNet model to detect faces.
Running this example requires a Luxonis device connected to your computer. Refer to the documentation to setup your device if you haven't done it already.
You can run the example fully on device (STANDALONE mode) or using your computer as host (PERIPHERAL mode).
Here is a list of all available parameters:
-d DEVICE, --device DEVICE
Optional name, DeviceID or IP of the camera to connect to. (default: None)
-fps FPS_LIMIT, --fps_limit FPS_LIMIT
FPS limit for the model runtime. (default: 20)
You need to first prepare a Python 3.10 environment with the following packages installed:
You can simply install them by running:
pip install -r requirements.txtRunning in peripheral mode requires a host computer and there will be communication between device and host which could affect the overall speed of the app. Below are some examples of how to run the example.
python3 main.pyThis will run the example with default arguments.
Running the example in the standalone mode, app runs entirely on the device.
To run the example in this mode, first install the oakctl tool using the installation instructions here.
The app can then be run with:
oakctl connect <DEVICE_IP>
oakctl app run .This will run the example with default argument values. If you want to change these values you need to edit the oakapp.toml file (refer here for more information about this configuration file).
