PointCloudStatisticsCalculator

Calculates statistics on point cloud components and adds the results as attributes.

Typical Uses

  • Inspecting and analyzing point cloud features
  • Calculating statistics for use in further operations

How does it work?

The PointCloudStatisticsCalculator receives point cloud features and calculates selected statistics on each one individually. The results are output on each point cloud feature.

Available statistics include:

  • Minimum
  • Maximum
  • Mean
  • Sum
  • Range
  • Standard Deviation
  • Median
  • Mode

Statistics may be calculated for any or all of these point cloud components:

  • x
  • y
  • z
  • intensity
  • color_red
  • color_green
  • color_blue
  • classification
  • return
  • number_of_returns
  • angle
  • flight_line
  • scan_direction
  • point_source_id
  • posix_time
  • user_data
  • gps_time
  • gps_week
  • flight_line_edge
  • normal_x
  • normal_y
  • normal_z

Statistics are stored as attributes, named <component>.<statisticname>, where <statisticname> will be one of the following: min, max, range, mean, stdev, sum, median, mode.

For example, if the median was calculated for component z, then an attribute named z.median would be added to the feature.

Examples

Usage Notes

  • To calculate point cloud statistics on a group of point clouds as a single entity, merge them prior to this transformer with the PointCloudCombiner transformer.

Choosing a Point Cloud Transformer

FME has a selection of transformers for working specifically with point cloud data.

For information on point cloud geometry and properties, see Point Clouds (IFMEPointCloud).

Parameters

Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.

Dialog Options - Tables

Transformers with table-style parameters have additional tools for populating and manipulating values.
