API概述

EasyIDP含有下面的几个模块

• Data Module : Download and provide path to example files.

• Point cloud Module : read, write, check and crop operation.

• GeoTiff Module : read, write, crop, and statistics operation.

  • cvtools Submodule : processing ndarray images.

• ROI Module : 从shp或txt文件中读取兴趣区域(ROI)

  • shp Submodule: read shape (*.shp) file.

  • jsonfile Submodule: read and write json and geojson file.

  • geotools Submodule: transform geo-coordinate.

• reconstruct Module : process 3D reconstruction software project.

  • Pix4D Submodule: handle Pix4D projects.

  • Metashape Submodule: handle Metashape projects.

• visualize Module : Draw visualization figures for the output.

每一个模块都由一些底层函数(如 easyidp.geotiff.* )和一个高级封装的类(如 easyidp.GeoTiff )组成。大部分情况下，除非特别需要，请使用大写的高级封装的类而不是小写的底层函数

例如，下面这个函数可以用来读取geotiff的元信息：

>>> import easyidp as idp
>>> header = idp.geotiff.get_header("one_geotiff_file.tif")

但是大部分情况下更推荐使用高级封装：

>>> geo = idp.GeoTiff("one_geotiff_files.tif")
>>> header = geo.header

尽管看上去代码数量变多了，但是高级封装有更方便使用的函数，而不用关心具体的数据结构细节。大部分的例子也使用高级封装的类

小心

The easyidp.Container object, its child objects, and objects contains this object, like easyidp.ROI , ProjectPool , easyidp.Recons , easyidp.Pix4D , easyidp.Metashape, can not be saved by pickle.
