Fiducial Markers

the fiducial markers are a series of markers that can be used with the ncam system to help with the recovery process key points the fiducials can be printed to any size fiducials are not always required if making your own, make sure they are printed onto a completely flat surface only ever use one of each type of fiducial in a space if the system see's the same pattern twice it will cause confusion when to use them with the updates in ncam reality 2023, it is not required to use the fiducials when operating in marker mode when operating in natural mode, and saving and reloading an alignment, then it can be useful to still use the fiducials how to use them if using the fiducials they should be placed into the environment in a position where they can easily be seen by the camera bar they should be in a fixed position, and after the fiducial has been learnt by the system then it should not be moved inside the reality software preferences, enable the "fiducial tracking" core with the system tracking, move the camera around your space and make sure that the camera bar can see the fiducial at some point during this movement in the 2d witness view, 5 white crosses will be displayed on the chart when it has been properly detected these are also represented in the 3d tracking view after the fiducials have been learnt the alignment can be saved as normal after the fiducials have been learnt, and the alignment saved, we recommend turning off the fiducial tracking mode it only needs to be activated when learning fiducials, any alignment that has fiducials learnt in it, will automatically turn it back on when needed when recovering sizes as a general rule on sizing 2 4 meters from mk2 camera bar to ceiling a3 4 6 meters from mk2 camera bar to ceiling a2 6 10 meters from mk2 camera bar to ceiling a1 the fiducial anchor chart may need additional lighting depending on where it can be mounted in the volume and this should be taken into account
