pipeline - 在 pdal 管道文件中读入和合并多个 .las

Question

我可以在管道文件中读取和输出单个 .las 文件。

如何读取两个 .las 文件，合并它们，然后根据以下示例应用过滤器和输出？

{
  "pipeline":[
    {
      "type":"readers.las",
      "filename":"E:\\offload\\3dspatial\\processed\\99.526\\201406071257\\201406071257.las",
      "spatialreference":"EPSG:32635"
    },
    {
      "type":"filters.chipper",
      "capacity":600
    },
    {
      "type":"writers.pgpointcloud",
      "connection":"host='localhost' dbname='db' user='user' password='pw'",
      "schema":"pointcloud_99_526",
      "table":"pc_201406071257",
      "compression":"dimensional",
      "srid":"32635"
    }
  ]
}

Answer 1

这似乎只是测试它。

{
  "pipeline":[
    {
      "type":"readers.las",
      "filename":"E:\\offload\\3dspatial\\processed\\99.526\\201607150650\\201607150650.las",
      "spatialreference":"EPSG:32635",
"tag":"A"
    },

    {
      "type":"readers.las",
      "filename":"E:\\offload\\3dspatial\\processed\\99.526\\201607140910\\201607140910.las",
      "spatialreference":"EPSG:32635",
"tag":"B"
    },


        {
            "type":"filters.merge",
            "tag":"merged",
            "inputs":[
                "A",
                "B"
            ]
        },


    {
      "type":"filters.chipper",
      "capacity":600
    },
    {
      "type":"writers.pgpointcloud",
      "connection":<info>,
      "schema":"pointcloud_99_526",
      "table":"pc_merge_201607150650_201607140910",
      "compression":"dimensional",
      "srid":"32635"
    }
  ]
}
