Webcam timing

Measure, analyze, and plot webcam frame timings.

Features

• Supports most USB webcams and Luxonis Oak cameras
• Measures time between frames
• Saves frame times in .csv file
• Logs statistics (e.g. frames per second, mean deviation) to console
• Shows plot

Setup

1. Create a virtual environment with a Python 3.10 interpreter
2. Run pip install -r requirements.txt to install dependencies
3. Configure the program for your camera by editing create_camera.py. Use the OpenCvCamera class for standard UVC webcams (e.g. Logitech C270) and the OakCamera class for Luxonis Oak cameras. If your camera is not supported, you can add support yourself by implementing the abstract base class CameraBase. Pull requests welcome!

Usage

• Run measure.py to create a .csv file containing the delays between frames
• Plots of existing csv files can be shown by running plot.py with the path to the file as argument
• Stats of existing csv files can be shown by running analyze.py with the path to the file as argument
• Run display.py to see the video stream of the camera. This is useful for troubleshooting
