camera-fusion

Multiple cameras correction calibration and fusion with OpenCV Python. This package use ChAruco board to achieve accurate multi-cameras fusion.

Installation

pip install camera-fusion

Depending of your environment, you could have to compile OpenCV from source with Python bindings.

Quickstart

Calibration

Print a ChAruco board, for example the one in the ./resources folder.

Measure the length of the Aruco marker and the length of the black chess square. Then start the calibration scripts.

Usage examples

Generate the lens correction calibration file for a specific camera.

python3 ./bin/camera_calibration

Generate homographies between multiple cameras to fuse/blend on a specific plane. If no lens correction calibration exist for the cameras, they will be generate.

python3 ./bin/camera_fusion

Simple blending methods are implemented:

  • Blue channel to RGB blending
  • Gray scale to RGB blending
  • Weighted blending
  • Difference

Use cases

This project was made to create a super low-cost degree of linear polarization imager. With three cheap repurposed webcams, we achieve decent results and frame-rate.
