Parameters
[out]pitchThe computed mean pitch (will be zero if buffer is empty)
[out]rollThe computed mean roll (will be zero if buffer is empty)
Return values
Returnsfalse if the buffer is empty

Definition at line 537 of file image_warp_util.cpp.

)

Computes the median pitch and roll.

Parameters
[out]pitchThe computed median pitch (will be zero if buffer is empty)
[out]rollThe computed median roll (will be zero if buffer is empty)
Return values
Returnsfalse if the buffer is empty

Definition at line 551 of file image_warp_util.cpp.

void swri_image_util::PitchAndRollEstimatorQueue::LoadNewData ( double  new_pitch,
double  new_roll 
)

Loads new pitch and roll data directly onto the buffer.

Parameters
[in]new_pitchNew pitch data
[in]new_rollNew roll data

Definition at line 566 of file image_warp_util.cpp.

void swri_image_util::PitchAndRollEstimatorQueue::SetBufferSize ( int32_t  buff_size = 50)
