-Print the 'chessboard.png' and stick it on a flat surface. Make sure the rectangles have a height and width of 2,5 cm.
If you are using camera's with lenses that have distortion (bend lines) you should calibrate them first before mounting them. Download and extract this zip file containing the SolARTool_CameraCalibration tool to a windows pc. The basic configuration has already been done, you will have to execute the following steps for every camera.
-Print the 'chessboard.png' and stick it on a flat surface. Make sure the rectangles have a height and width of 2,5 cm.
--Connect the camera to the pc.
-Start the SolARTool_CameraCalibration.exe. If the camera view shows the wrong camera close the application and open the 'SolARTool_CameraCalibration_conf.xml'. Increase the DeviceId, save the file and start the application until the right camera is shown
-Press 'g' to start calibrating the camera. Every 2 seconds an image is taken for a total of 30 images. Move the chessboard every 2 seconds a bit, in the end covering as much of the whole image as possible.
After the calibration has finished a file 'camera_calibration.json' is created in the directory. Save this so you can upload it for this camera in the Gungnir Dartstracker later on.
