Using a Custom Fiducial Constellation
1.
The process of creating a fiducial map that will ensure accurate tracking quality is covered in the Fiducial Constellation Setup
Guide. If needed, contact Thales Visionix Technical Support for further information on how to create a constellation.
2.
Once the custom constellation is in place, it will need to be mapped before the IS-1500 can track off of it. The map informs the
IS-1500 system what fiducial IDs to expect and at what placements. One of the fiducials can serve as the origin of the constellation.
The origin also can be easily edited to be any point once the map has been created using the sfStudio Constellation Display tools.
It is important to note that the Simple Visual Mapping tool used to generate map files can only run on Windows operating systems.
3.
The map file is saved as the environmentPSEs.cfg in the sfStudio subfolder. Start by creating a copy of the current file and
renaming it, for example, to FidPoster.cfg. The system requires environmentPSEs.cfg to be the name of any map in use, and the
tool used for mapping will overwrite any file that currently has that name. It is therefore very important that an existing map file
be copied and saved under a different name before another map file is created. Keeping backups of constellations allows the
users to revert to a previous constellation or switch between them without needing to recreate the map files.
4.
With sfStudio connected to the InertiaCam, select the Simple Visual Mapper in the Tools dropdown of sfStudio. From here, the
Simple Visual Mapper Tool section will cover the process of mapping the custom constellation. See also the sfStudio User Guide
(MNL-0020) for more details.
5.
When mapping is complete, the SVM tool automatically saves it on your computer.
6.
If the IS-1500 is able to reach State 2 using the new map, it is recommended that a backup of this custom map file also be created.
