It is important to calibrate the structure sensor so it can give the best performance in capturing accurate measurements. Calibrations are required regularly, depending on usage could be weekly or monthly.
A poorly calibrated structure sensor can lead to:
There is a two-step process to calibrate your scanner: Stereo Calibration and Depth Calibration
Prior to beginning the process, make sure your structure sensor is fully charged and that the Structure Sensor Calibrator' app is installed on your ipad.
Steps to installing the Structure Sensor Calibrator app:
> Open the App Store
> Search Structure Sensor Calibrator
> Select 'Get' beside the application
For additional information on the Calibrator app go to (https://support.structure.io/article/382-getting-started---how-to-use-the-calibrator-app)
This calibration will make sure that the images from both cameras, the iPad and the Infrared image from the sensor are perfectly aligned, and overlayed one over the other.
When you start a scan and you don't have a solid red pattern over the body part you are aiming to scan, when you have a broken pattern with holes or only a few red dots or if the scan box is unstable, you need to do a depth calibration.
