For this tutorial, you'll need

  1. A bright space

    1. indoor mode may require recalibration later

  2. Structure sensor and iPad

  3. The structure sensor calibrator app

  4. An internet connection

Why Calibrate?

Calibration doesn't increase the resolution of your scan, but improves the color and depth alignment of the scan.

If the bounding box bounces, flips, or wiggles- the cause is most often due to depth. Click here to see an article from Occipital on refining depth calibration.

1. Let's begin calibrating! First, open the app.

2. You'll need

  • A well lit area

  • An area with many angles, corners and dimensions is ideal

  • Slowly pan the scanner across the room, pausing occasionally

Panning slowly allows Structure sensor to determine if wide lens is attached. Pause for blue dots to be applied. Pro Tip: More blue dots = better calibration

3. Tap the screen to begin calibration. This will connect the scanner to the calibration server.

4. Now you'll be asked to move the scan to better match the background. In the example, we'll move our scan a bit to the right.

5. Last, you'll need to save your calibration to the sensor. 

Congrats! You just calibrated your structure sensor!
