Now, any time streaming is set, a new log file will be created. It is possible for this to happen multiple times during a single
sfHub session, especially since actions like connecting to sfStudio will start and stop streaming of data.
a.
Using sfHub by itself will be cleaner and ensure only one log is created, but will not allow the user to view the data
as it is being collected.
i.
To do this, run the sfHub program directly from the sfHub folder that sfHub.info was found in.
ii.
Allow a few seconds for sfHub to find the tracker and begin tracking (see Figure 33).
Figure 33 – sfHub Tracking
iii.
When the sfHub output appears as it does in Figure 33, with Streaming On, the Filter Initialized, and the
whirligig next to S1 turning freely, tracking is running and the data collection has begun. Perform the
tracking run to collect the desired data.
iv.
The log is generated continuously as sfHub is streaming and does not need a special save process. When
finished with data collection, simply close the sfHub window.
b.
Using sfStudio will allow a user to look at the data as it’s begin collected, but has the potential to create small,
throwaway log files that will need to be discarded manually from the system later.
i.
Open sfStudio.
ii.
If you would like to watch any displays while tracking (such as 3D Data display or Optical Data Display), open
these and drag them off to their own windows now. (These displays only need to be open for convenience,
all displays will be usable when the log is played back, not only the ones currently in use.)
iii.
Click the Connect button to automatically launch and connect to sfHub.
iv.
Perform the tracking run to collect the desired data.
v.
The log is generated continuously as sfHub is streaming and does not need a special save process. When
finished with data collection, simply close sfStudio and sfHub.
6.
When the desired data logs have been collected, remember to disable logging by repeating steps 1-4, this time setting
logData
0
.
The log files are automatically generated in the logs subfolder of the sfHub folder. They can be found in ./sfHub/logs/<InertiaCam
Serial Number>/<Date/Time Stamp>. For instance, if a log was created using an InertiaCam with serial number ICM-1705998-3 at
12:52PM on July 11, 2017, this log would be the ./sfHub/logs/ICM-1705998-3/2017-07-11_12.52.23PM folder. If sfStudio was used
to create logs, the small throwaway log folder can usually be identified by looking at the folder size. Those with drastically smaller file
sizes than the others are unlikely to contain the data that was collected. This can always be confirmed by simply playing back the log
files.
