camera-capture-system

Description

A system that:

1. captures USB camera feeds using openCV with platform specific backends
2. syncronizes the video feeds and adds metadata
3. sends the resulting frame and metadata over a network connection using ZMQ PubSub

Usage

clone the repo and cd into it

git clone https://github.com/kristina-aino/camera-capture-system.git
cd camera-capture-system

poetry setup, test and build

poetry install
poetry run pytest
poetry build

create the config file for your camera setup

Example

{
  "cam0": {
    "id": 1,
    "width": 1920,
    "height": 1080,
    "fps": 30,
    "name": "A-webcam",
    "position": "center"
  },
  "cam1": {
    "id": 0,
    "width": 1920,
    "height": 1080,
    "fps": 60,
    "name": "Another-webcam",
    "position": "center-right"
  },
}

• "cam0", "cam1", etc. is considered the uuid and is required to be unique (enforced by json standard)
• "id" is the OpenCV id the camera runs under
• "width", "height" and "fps" are camera specification
• "name" and "position" are human redables with no logical value

Start the capture and publishing on localhost port 10000

poetry run python main.py

Or use it as a module

from camera_capture_system.core import load_all_cameras_from_config, MultiCameraCaptureAndPublish

cameras = load_all_cameras_from_config(path_to_conf)

pccp = MultiCameraCaptureAndPublish(cameras=cameras)
pccp.start()
