• Free software: MIT license
• Documentation: https://rpi-deep-pantilt.readthedocs.io.

Basic Setup

Before you get started, you should have an up-to-date installation of Raspbian 10 (Buster) running on your Raspberry Pi. You'll also need to configure SSH access into your Pi.

• Install Raspbian
• Configure WiFi
• Configure SSH Access

Installation

1. Install system dependencies

sudo apt-get update && sudo apt-get install -y \
    cmake python3-dev libjpeg-dev libatlas-base-dev raspi-gpio libhdf5-dev python3-smbus

2. Install the rpi-deep-pantilt package.

pip install rpi-deep-pantilt

Example Usage

Real-time object detection

The following will start a PiCamera preview and render detected objects as an overlay. Ensure you're able to detect an object before trying to track it.

rpi-deep-pantilt detect

rpi-deep-pantilt detect --help

Usage: rpi-deep-pantilt detect [OPTIONS]

Options:
  --loglevel TEXT  Run object detection without pan-tilt controls. Pass
                   --loglevel=DEBUG to inspect FPS.
  --help           Show this message and exit.

Real-time object tracking

The following will start a PiCamera preview, render detected objects as an overlay, and track an object's movement with the pan-tilt HAT.

By default, this will track any person in the frame. You can track other objects by passing the --label

rpi-deep-pantilt track

rpi-deep-pantilt track --help 
Usage: rpi-deep-pantilt track [OPTIONS]

Options:
  --label TEXT     The class label to track, e.g `orange`. Run `rpi-deep-
                   pantilt list-labels` to inspect all valid values
                   [required]
  --loglevel TEXT
  --help           Show this message and exit.

Credits

The MobileNetV3-SSD model in this package was derived from TensorFlow's model zoo, with post-processing ops added.

The PID control scheme in this package was inspired by Adrian Rosebrock tutorial Pan/tilt face tracking with a Raspberry Pi and OpenCV

This package was created with Cookiecutter and the audreyr/cookiecutter-pypackage project template.
