Class: QgsPointCloudStatistics

Used to store statistics of a point cloud dataset.

Added in version 3.26.

Methods

classesOf	Returns a list of existing classes which are present for the specified attribute
clear	Clears the statistics of all attributes
combineWith	Merges the current statistics with the statistics from stats
maximum	Returns the maximum value for the attribute attribute If no matching statistic is available then NaN will be returned.
mean	Returns the mean value for the attribute attribute If no matching statistic is available then NaN will be returned.
minimum	Returns the minimum value for the attribute attribute If no matching statistic is available then NaN will be returned.
sampledPointsCount	Returns the number of points used to calculate the statistics
stDev	Returns the standard deviation value for the attribute attribute If no matching statistic is available then NaN will be returned.
statisticsOf	Returns the calculated statistics of attribute attribute
toStatisticsJson	Converts the current statistics object into JSON object
