moments_object_model_3d — Calculates the mean or the central moment of second order for a 3D object
model.
moments_object_model_3d( : : ObjectModel3D, MomentsToCalculate : Moments)
moments_object_model_3d calculates the mean or
the central moment of second order for a 3D object model.
To calculate the mean of the points of the 3D object model,
select 'mean_points'
in MomentsToCalculate. If instead the central moment
of second order should be calculated, select
'central_moment_2_points'. The results are the variances
of the x, y, z, x-y, x-z, and y-z axes.
To compute the three principal axes of the 3D object model
select 'principal_axes' in MomentsToCalculate.
The result is a pose with the mean of the points as center. The
coordinate system that corresponds to the pose has the
x-axis along the first principal axis, the y-axis along the second
principal axis and the z-axis along the third principal axis.
ObjectModel3D (input_control) object_model_3d(-array) → (handle)
