计算和在每个点云特征上计算和输出统计信息。如果要计算聚合中的一组点云的点云统计信息，请在此变压器之前合并它们PointCloudCombiner。
Input Ports
Input
This transformer accepts only point cloud features.
输出端口
输出
Features with the calculated statistics are output through this port.
参数
计算统计数据
指定要为每个组件计算的统计信息。
The following statistics may be calculated:
- 最小值：数字组件的数值最小值。字符串组件的词汇最小值。
- Maximum: The numerical maximum for numeric components. The lexical maximum for string components.
- Range: The maximum minus the minimum. Undefined for string components.
- 均值：平均值，计算为值的总和除以点数。字符串组件未定义。
- Standard Deviation: The standard deviation as measured by the "nonbiased" or "n-1" method. Undefined for string components.
- 总和：所有值的总和。字符串组件未定义。
- 中位数：如果点数是奇数，或者如果点数是偶数，则在命令中列出值时的中间值。对于字符串组件，始终使用第一个中间值。
- Mode: The most frequent of all the values. If the dataset is bimodal (two or more values occur with the highest frequency) one of the values will be returned randomly.
统计数据将作为特征上的属性存储。属性将被命名
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, seeTransformer Parameter Menu Options。
