During the system calibration wand (or rod) process, we are aiming for two benchmarks.
1. A rating of "excellent calibration"
2. An error value < 1.0
In the event that you receive a high error value as shown above, address the following items then repeat calibration:
- Ensure there is nothing reflective in the calibration field by using the Snap feature to analyze the environment for any additional reflectivity present during calibration
- Ensure no reflectivity present on user completing the calibration by using the Snap feature
- Ensure the environment is not changing during the calibration process.
- Ex: others in the area walking through the field, a door opening with a reflective door knob, etc.
- Ensure there are no mirrors or windows in the view of the camera that could be reflecting images of the markers
- Check the condition of your wand (or rod) to ensure no movement of the calibration markers has occurred. (If this has occurred please Submit a Request)
- Ensure camera intensity is set appropriately (Typically between 2-4) (Camera Exposure Article)
- Ensure you are not stepping too close to the camera bar during calibration
- You should not need to move any closer to the cameras than the back of the treadmill
- Repeat calibration by following the procedure outlined in the Camera Exposure, Wand Calibration, and Set Reference article
