btkGetEvents
Description
Extracts events from a biomechanical acquisition.
Parameters
| h | Handle pointing to a C++ btk::Acquisition object. |
Returned Values
| events | structure where each field corresponds to an event's label |
| eventsInfo | structure with additional informations- eventsInfo.subjects: contains the name of the subject for each event
- eventsInfo.units: structure with a single field named ALLEVENTS for the unit used by the events.
|
Detailed Description
The value of each field in the output
event corresponds to the time(s) where this event occurred.
If the events represent actions realized by more than one subject, each event starts by the name of the corresponding subject. The time(s) of each event are reordered. Events are also reordered based on their first time.
Events' time are computed using the following formula:
t = (event_frame - first_frame) / sample_frequency
Hence, an event set to the first frame of the acquisition, will have a (relative) time computed to 0.0 second.
