This video demonstrates how to read point cloud data formatted as delimited text files.本文还介绍了其他类型的点云。您将看到如何定义分隔符和组件字段。
FME可以从三种基本格式中读取点云数据:
A complete list of supported point cloud formats is available on the格式化页面。
下面提供了读取这三种点云格式的步骤。An FME Workspace Template which includes sample data and a reader for all three types can be downloaded using the link on this article.
The LAS reader can be used to read compressed LASzip files (.laz),esri las数据集(.lasd)和压缩的esri.zlas文件。When reading data in LAS format (ASPRS Lidar Data Exchange) the components such as x,y,z,intensity etc are defined in the format so it is not necessary to specify these when adding the reader.
Currently Oracle Spatial is the only true database point cloud format supported by FME.请注意,从该格式读取允许您在读卡器参数中指定搜索信封,以优化特定区域的读取。To use the Oracle Spatial Point Cloud format you must have an Oracle client library installed.
FME includes a flexible Point Cloud XYZ reader for reading text data which includes at a minimum x,y,z columns and possibly other components such as intensity,classification etc.This reader makes it possible to read many types of data into a point cloud even if this was not the initial purpose of the data.When adding a reader for XYZ files it is necessary to define the delimiter and component fields as shown in the steps below.链接到本文的FME工作区模板包括一个读卡器和这个点云XYZ格式的示例数据。
