Realtime data¶
Flydra is capable of outputing a low latency stream of state estimate from the Kalman filter.
The data are originally encoded into a “data packet” by
flydra_core.kalman.flydra_tracker.Tracker.encode_data_packet()
.
Then, they are transferred to a separate thread in the
flydra_core.MainBrain.CoordinateSender
class. There, multiple
packets are combined into a “super packet” with
flydra_core.kalman.data_packets.encode_super_packet()
. By combining
into a single buffer to send over the network, fewer system calls are
made, resulting in better performance and reducing overall latency.
