[人工智能]图像处理工具3——进行图像文件的拷贝（不只是图像文件）

1 进行文件的拷贝，不只是图像文件

# 这个文件的作用是复制负样本的文件

import os
import gdal
import numpy as np
import time


def Positive(nature_to_path,label_path,label_to_path,img_path,img_to_path,):
    """
    进行负样本文件的拷贝
    :param nature_to_path:负样本已经存在的的文件夹
    :param label_path:全部的标签
    :param label_to_path:要复制到的负样本标签文件夹
    :param img_path:全部的影像
    :param img_to_path:要复制到的负样本影像文件夹
    :return:
    """
    filenames = os.listdir(nature_to_path)
    print(len(filenames))
    for filename in filenames:
        # 1 拷贝标签
        file_path = os.path.join(label_path, filename)
        label_to = os.path.join(label_to_path, filename)  # 路径2拼接
        with open(file_path, "rb") as f:
            res_one = f.read()
            with open(label_to, "wb") as a:
                a.write(res_one)

        # 2 拷贝rawdata
        remote_path = os.path.join(img_path, filename)

if __name__ == '__main__':
    start = time.time()
    Positive(
        nature_to_path=r"I:\5GF2\5dataset\3NegativeData\3Negativenaturedata",

2 拷贝含指定名字的图像

for filename in filenames:
    if filename[0:8] in names:
        # 1 拷贝标签
        file_path = os.path.join(path_png, filename)
        label_to = os.path.join(path_to_png, filename)  # 路径2拼接

print("images ok")
