🔧 Installation
Dependencies
This package forms an essential part for my docker-based real-time 3d tracker. It mainly depends on these two modules
To build the package, simply run:
bash
./scripts/build.sh
Usage
1. Prepare a Calibration Target
Use a ChArUco board similar to the one shown in the example image above.
To get you started we provide a bitmap file in ./content/board_pattern.MCC_Patt1040x720.bmp. You can use GIMP to rescale and print the file with a size of 1040 x 720 mm, including the white border. The configuration bellow matches this exact calibration target.
2. Configure Calibration Settings
Edit the configuration file ./cfg/CameraCalibrationSettings.json to match your setup:
json
{
"pattern_size_first": 11,
"pattern_size_second": 7,
"charuco_params_border_size": 1.0, # pixels
"charuco_params_dict": 0, # dict id
"charuco_params_marker_border_pixel": 1,
"charuco_params_marker_to_square_ratio": 0.75,
"charuco_params_square_size": 80.0, # mm
"savedir": "/home/docker/workspace/workspace/multi-camera-calib/data/results"
}
3. Run the calibration routine
Start the calibration process:
bash
./scripts/calibration.sh
What the script does:
- Waits 10 seconds for you to get the calibration board into view
- Records video for 15 seconds from each camera
- Extracts frames from the video streams
- Runs the calibration using the extracted frames
- Validates the calibration and stores results in
./test
Make sure to move the calibration board smoothly and visibly during the recording phase (approx. 25 seconds total).
Acknowledgements
The core of the calibration code is adapted from Multi_Camera_Calibration. To streamline re-calibration, the GUI was removed and replaced with JSON-based configuration.
