PDAL筛选器不工作：无法分析pipelin

Question

所以这是我第一次使用PDAL。我使用python3.6和pdal1.9

 json_s = """{


        "test.las",
        {
        "type":"filters.outlier",
        "method":"statistical",
        "mean_k":12,
        "multiplier":0.5
        },
        {
        "type":"filters.range",
        "limits":"Classification![7:7]"
        },
        "testOut.las"

}"""

pipeline = pdal.Pipeline(json_s)
count = pipeline.execute()

它显示了错误

RuntimeError: JSON pipeline: Unable to parse pipeline. 

我检查了网站上的样本代码，它看起来是一样的。只是不知道为什么不行

Answer 1

PDAL格式如下所示：

json_s = """{

 "pipeline":[
        "input.las",
        {
          #anything you need
        },

        "output.las"
       {
       }
    ]
}"""

在您的情况下，请尝试：

json_s = """{

 "pipeline":[
        "test.las",
        {
        "type":"filters.outlier",
        "method":"statistical",
        "mean_k":12,
        "multiplier":0.5
        },
        {
        "type":"filters.range",
        "limits":"Classification![7:7]"
        },
        "testOut.las"
    ]
}"""
