Statistics are calculated and output on each point cloud feature individually. If you want to calculate point cloud statistics on a group of point clouds in aggregate, merge them prior to this transformer with thePointCloudCombiner。

Parameters
Statistics to Calculate
Specifies which statistics to calculate for each component.
下面的统计数据可以计算：
- Minimum: The numerical minimum for numeric components. The lexical minimum for string components.
- 最大：用于数字部件的数值最大。字符串组件词法最大。
- Range: The maximum minus the minimum. Undefined for string components.
- Mean: The average value, calculated as the sum of values divided by the number of points. Undefined for string components.
- 标准偏差：由“nonbiased”或“n-1”方法测量的标准偏差。未定义的字符串组成部分。
- Sum: The sum of all values. Undefined for string components.
- Median: The middle value when the values are listed in order if the number of points is odd, or the average of the two middle values if the number of points is even. For string components, the first middle value is always used.
- 模式:最常见的所有值。如果dataset is bimodal (two or more values occur with the highest frequency) one of the values will be returned randomly.
Statistics will be stored as attributes on the feature. Attributes will be named<组分> <统计>, where statistic is one of the following:分,max,范围,mean,stdev,和,中位数,mode。例如，如果计算了部件中位数z, then an attribute namedz.medianwould be added to the feature.
编辑变压器参数
使用一组菜单选项，变压器参数可以通过引用在工作区中的其它元件来分配。更先进的功能，如高级编辑，算术编辑，也是一些变压器可用。要访问这些选项的菜单，点击
