calibration
Application for intrinsic calibration:
You can create your own camera calibrations using ProCamCalib. Clone ProCamCalib. ProCamCalib allows you to calibrate your camera using a printed sheet of markers and comparing distances between pixels and centimeters. You can have a detailed explanation on how to use ProCamCalib here.
You will have to print the file sketchbook/libraries/PapARt/data/procamcalib/board.svg (A3 size).
Launch ProCamCalib.
Go to Settings > Load... and load the file sketchbook/libraries/PapARt/data/procamcalib/settings.pcc.
Click on projector in the left panel ; on the right change quantity to 0 (as we just want to calibrate the camera) and press enter to save.
In the left panel, go to Cameras > CameraX where X is the number of your camera. In the right panel select OpenCV as a FrameGrabber.
Put the printed sheet in front of the camera, on a planar surface. Press the PLAY button. A popup should open and display the camera feed. Each marker should have a symbol on it. The application takes automatically pictures to calibrate the camera, so you just have to move the sheet of paper in different positions.
Your camera is properly calibrated!
