template class mrpt::poses::SE_average<2>

Computes weighted and un-weighted averages of SE(2) poses.

Add values to average with append(), when done call get_average(). Use clear() to reset the accumulator and start a new average computation. Theoretical base: See SO_average<2> for the rotation part. The translation is a simple arithmetic mean in Euclidean space. Class introduced in MRPT 1.3.1

Fields

bool enable_exception_on_undeterminate {false}

(Default=false) Set to true if you want to raise an exception on undetermined average values.

Methods

void clear()

Resets the accumulator.

void append(const mrpt::poses::CPose2D& p)

Adds a new pose to the computation.

See also:

get_average

void append(const mrpt::poses::CPose2D& p, const double weight)

Adds a new pose to the weighted-average computation.

See also:

get_average

void get_average(mrpt::poses::CPose2D& out_mean) const

Returns the average pose.

Parameters:

std::logic_error	If no data point were inserted.
std::runtime_error	Upon undeterminate average value (ie the average lays exactly on the origin point) and enable_exception_on_undeterminate is set to true (otherwise, the 0 orientation would be returned)
