Noise

Noise is a result of issues with the tracking quality. From a troubleshooting perspective this means that the following calibrations aren't relevent in trying to resolve it:

Noise is a result of either:

The steps for addressing troubleshooting differ slightly between Natural and Marker modes but in both cases we need to essentially understand whether noise is being generated by the CamBar or the environment

Test - Observe Tracking Features

As a first step it's important to consider the current tracking environment the CamBar is tracking in. Is there visible movement in the tracking features detected in the UI

Can the CamBar be orientated to find more stable tracking features

Can the additional features be added to the environment to support tracking

Test - Pointcloud Cleanup

Does the tracking quality significantly improve after a "pointcloud Cleanup" is conducted? This can indicate that the pointcloud was containing too many incorrect tracking features (lighting changes, moving objects etc)

For longterm tracking consider locking the pointcloud or moving to marker mode

Test - Check for unexpected loss of tracking features

Observe the detected tracking features in the UI, are stable tracking features dropping in and out of detection? This is a strong indicator that there is an issue with the CamBar calibration

Test - Check Pixel Error

The pixel error can provide an indication of the CamBar calibration, when starting the tracking, is the initial value average or higher?

This can indicate that the CamBar calibration is poor. The pixel error alone should not be used as the single indicator of CamBar quality however, as the environment and type of features being tracked can also impact pixel error

When operating in Marker mode, as the system is using fixed markers in a locked pointcloud, it's less likely that noise is being generated from pointcloud pollution

Test - Check for movement in detected markers

The marker tracking core looks for the centre of markers, check to see if any visible "wobble" or movement can be seen in the UI

Adjust CamBar lighting to see if detection of the marker can be stabilised

Consider physically removing specific markers

Test - Check for intermittantly detected markers

Are some markers dropping in and out of detection when the camera is stationairy? This can be typcially caused by insufficent IR lighting or falloff towards the edge of the camera frame. Markers that drop in and out of detection, particularly when only tracking a handful of markers can introduce noise

Can CamBar lighting be adjusted to stabilise marker detection?

Can larger markers be used to reduce IR light falloff?

Test - Cover one lens

Does noise reduce significantly when covering one of the CamBar cameras?

This is a strong indication that the CamBar Calibration is poor

Test - Is noise present everywhere?

Is noise visible in the camera tracking across the whole marker area?

If it's only present in certain parts of the environment then it is likely caused by poor marker placement/detection instead of CamBar calibration

In the areas where noise is present:
