Intrinsics

Intrinsics is enabling each camera to distinguish real world coordinates based on the camera’s physical configuration

• You will calibrate intrinsics:
  • If the settings on the physical camera change (zoom, brightness, focus)
  • If DARI support suggests that you recalibrate

1. In DARI Capture, click the ‘CALIBRATE’ tab on the left
2. Click the ‘Intrinsics’ tab on the right
3. Click ‘Capture Calibration Board’
4. Show the calibration board to any camera or just the camera in need of intrinsic calibration), keep it horizontal and parallel to the lens
5. Move the board around to cover the area the camera can see until coverage is at least 75%
6. Angle the board reach as high of a max angle as possible, some cameras will be more difficult than others, a goal should be about 60°. If it takes more than a minute to achieve, move on to the next camera.
7. Repeat on all necessary cameras
8. Click ‘Stop Capturing Calibration Board’ when you are done
9. Click ‘Calibrate Intrinsics’ and wait for the calculations to complete, this can take some time if a lot of time was spent calibrating.
10. Check the calibration error in the ‘Error’ column
11. Ensure all pixel errors are yellow or green in color
12. If they are red, click the trashcan icon to delete the calibration and repeat steps 3-11
