skellycam 2024.9.1094

Top-level package for skellycam.

SkellyCam

An easy and efficient way to connect to one or more cameras and record synchronized videos 💀📸

---

Motivation

Connecting to cameras on multiple platforms in a way that is not slow is a difficult challenge, especially for new developers.

There are a bunch of tools out there (e.g. OpenCV) and other open source libraries that give just enough to support hardware manipulation, but they need to be use in concert in order to be useful.

This library attempts to string those things together, and provide an interface for everyone to use in python with a simple pip install.

The primary focus is to provide an easy method to connect to one or more cameras and provide methods for streaming/recordig synchronized frames from the connected cameras.

NOTE - The SkellyCam package is the primary camera backend for the freemocap markeless motion capture software 💀✨

Installation and Usage

0. Open a terminal (ideally with a python virtual environment activate)

1. Install from Pip

Enter the command below and press 'Enter'

pip install skellycam

2. Launch SkellyCam GUI

Enter the command below and press 'Enter'

skellycam

3. Success! 💀📸✨

Hopefully a bunch of text scrolled by and a GUI popped up!

If not, please open an issue on the github repo and we'll try to help you out :)

Limitation (aka TO DO) -

• Currently uses opencv to connect to cameras, so it won't recognize hardware that can't be connected with cv2.VideoCapture - Support for other camera hardware (e.g. FLIR) coming soon
• Camera streams are not synchronized at run time, but are saved and synchronized after the fact. This is time-consuming process that requres frames be saved in RAM until the recording is done. Both of these weaknesses have solutions in the works.

New Python developers

1. Install Python 3.10
2. Create Virtual Environment
3. Install skellycam

How to use

RECOMMENDED - Use the GUI!

Launch the GUI by running skellycam in a terminal.

This is currently the most tested method for interacting with the cameras.

Example 1 - Connecting to a single Camera and showing the video feed

Example 1 Python Fle

In this example, we connect a camera at index 0. Calling show allows us to view the cameras frames allowing us to see video.

NOTE - Work in progress, no clean way to kill this window yet

from skellycam import CameraConfig, Camera

if __name__ == "__main__":
    cam1 = Camera(CameraConfig(cam_id=0))
    cam1.connect()
    cam1.show()

Example 2 - Connect to all available cameras and record synchronized videos

NOTE - Experimental and under development, might be unstable

Example 2 Python Fle

from skellycam.experiments import MultiCameraVideoRecorder

if __name__ == "__main__":

    synchronized_video_recorder = MultiCameraVideoRecorder()
    synchronized_video_recorder.run()
