点云统计计算器
Statistics are calculated and output on each point cloud feature individually.如果要计算一组点云的点云统计数据的总和,merge them prior to this transformer with the点云合并器.
Input Ports
输入
此转换器只接受点云功能。
输出端口
Output
具有计算出的统计信息的特性通过这个端口输出。
Parameters
要计算的统计信息
Specifies which statistics to calculate for each component.
可计算以下统计数据:
- 最小值:数值分量的最小值。The lexical minimum for string components.
- 最大值:数值组件的最大值。字符串组件的词法最大值。
- 范围:最大值减去最小值。未定义字符串组件。
- Mean: The average value,calculated as the sum of values divided by the number of points.未定义字符串组件。
- Standard Deviation: The standard deviation as measured by the "nonbiased" or "n-1" method.未定义字符串组件。
- sum:所有值的总和。未定义字符串组件。
- 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.对于字符串组件,总是使用第一个中间值。
- 模式:所有值中最常见的。If the 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.属性将被命名
编辑变压器参数
使用一组菜单选项,可以通过引用工作区中的其他元素来指定变压器参数。More advanced functions,例如高级编辑器和算术编辑器,are also available in some transformers.要访问这些选项的菜单,点击beside the applicable parameter.更多信息,see变压器参数菜单选项.
