Changes

1. * Download and the camera calibration application from the release portal (link). 2. * Print the asymmetrical circle calibration pattern from the release portal (link). 3. * Verify the correct size by measuring the reference length on the upper right corner. 4. * Mount the calibration pattern on a planar surface. 5. * Install and open the Camera Calibration application. 6. * Target the calibration pattern with the camera (the pattern gets augmented --> check if the augmentation is placed at the center of the circles before taking a calibration screenshot). 7. * Tap on the display to mark a frame for calibration. a. ** The calibration pattern should take up aus much of the camera view as possible. b. ** Keep the camera and calibration pattern stable to not introduce blur. c. ** Take calibration frames from different viewpoints. d. ** Circles of the calibration pattern should also be in the corners of the camera view. e. ** Take as much calibration frames as possible (at least 30). 8. * After having enough calibration frames, open the menu and press calibra-tion. 9. * A toast indicates that calibration was done and shows the reprojection er-ror. This error should be as low as possible (lower than 3). 10. * The camera matrix and distortion coefficients are now saved on the device in the Downloads folder. The device name is used as the filename of the textfile. 11. * Forward the calibration file to the development department.
