我刚用pip安装了Liblas:

C:\Users\Geri>pip install liblas
Requirement already satisfied (use --upgrade to upgrade): liblas in c:\python27\arcgis10.2\lib\site-packages
Requirement already satisfied (use --upgrade to upgrade): setuptools in c:\python27\arcgis10.2\lib\site-packages (from liblas)

当我想导入模块时,我得到以下内容:

>>> import liblas
Runtime error 
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "C:\Python27\ArcGIS10.2\lib\site-packages\liblas\__init__.py", line 2, in <module>
    from core import get_version
  File "C:\Python27\ArcGIS10.2\lib\site-packages\liblas\core.py", line 136, in <module>
    las = ctypes.CDLL(lib_name)
  File "C:\Python27\ArcGIS10.2\Lib\ctypes\__init__.py", line 365, in __init__
    self._handle = _dlopen(self._name, mode)
WindowsError: [Error 126] The specified module could not …

我尝试使此代码打开LAS文件进行更改,然后将结果保存到新的LAS文件中.las文件包含具有坐标(X和Y)和值(如高程的Z)的点.不幸的是,如果我没有将保存部分放入其中,代码可以工作,但是当我在下面这样做时,我收到以下错误:

Traceback (most recent call last):
  File "C:\Users\Geri\Desktop\Sync\pythonlas\envisecond.py", line 33, in <module>
    listx1=p.append(listx1, float[newx])
AttributeError: 'float' object has no attribute 'append'
enter code here

到目前为止,我知道我需要一个数组来将值保存到代码末尾的las文件中:

import laspy
import laspy.file
import numpy as p
header = laspy.header.Header()
inFile2 = laspy.file.File("C:\\Users\\Geri\\Desktop\\Sync\\pythonlas\\mapperclip\\2clip.las", mode = "r")
inFile3 = laspy.file.File("C:\\Users\\Geri\\Desktop\\Sync\\pythonlas\\mapperclip\\3clip.las", mode = "r")
point_records = inFile2.points
point_records = inFile3.points

t=0
listx1=p.array([], dtype=float)
listy1=p.array([], dtype=float)
listz1=p.array([], dtype=float)
while t < 415:
    z=0
    q=0
    p=0.1
    while z==0:

        xmin=inFile3.x[t]-p
        ymin=inFile3.y[t]-p
        xmax=inFile3.x[t]+p
        ymax=inFile3.y[t]+p
        n=0
        for points in inFile2.points:
            ax=inFile2.x[n] …
