Bàn luậnUsing os.listdir
Trong bài viết này, chúng ta sẽ học cách lặp lại thông qua các hình ảnh trong một thư mục trong Python. & NBSP;
- Phương pháp 1: Sử dụng Os.ListDiros module to interact with the operating system.
- Ví dụ 1: Chỉ lặp qua .png chỉlistdir[] function from os to get access to the folders given in quotes.
- Lúc đầu, chúng tôi đã nhập mô -đun HĐH để tương tác với hệ điều hành.os.listdir[] function, we iterate through the images and printed the names in order.
- Sau đó, chúng tôi nhập chức năng listDir [] từ HĐH để có quyền truy cập vào các thư mục được đưa ra trong báo giá..png files to be loaded using the endswith[] function.
Python3
Sau đó, với sự trợ giúp của hàm Os.ListDir [], chúng tôi lặp lại thông qua các hình ảnh và in các tên theo thứ tự.
Ở đây chúng tôi chỉ đề cập đến & nbsp; .png sẽ được tải bằng hàm endswith [].

Tôi đang sử dụng Python, Open, Numpy và Scipy. Tôi có một thư mục hình ảnh mà tôi muốn xoay theo một số góc nhất định. Tôi muốn tập lệnh này. Tôi đang sử dụng điều này, OpenCV Python xoay hình ảnh theo độ x xung quanh điểm cụ thể nhưng dường như nó không chính xác như tôi đã hình dung. Tôi nhận được một kế hoạch xoay vòng không hợp lệ được chỉ định, nhưng tôi không nghĩ rằng tôi nên nhận được điều này.
Đây là mã của tôi trông như thế nào:
from scipy import ndimage
import numpy as np
import os
import cv2
def main[]:
outPath = "C:\Miniconda\envs\.."
path = "C:\Miniconda\envs\out\.."
for image_to_rotate in os.listdir[path]:
rotated = ndimage.rotate[image_to_rotate, 45]
fullpath = os.path.join[outPath, rotated]

Bạn cần thực sự đọc tệp hình ảnh trước khi xoay chúng. Những gì mã hiện tại của bạn đang làm chỉ là lặp lại thông qua tên của các tệp [và thư mục].
Os.ListDir [đường dẫn] cung cấp cho bạn một danh sách các nội dung của thư mục [về cơ bản chỉ là tên] và sau đó bạn cần mở các tệp này bằng hàm ndimage.Imread [].
Điều này sẽ hoạt động:
from scipy import ndimage, misc
import numpy as np
import os
import cv2
def main[]:
outPath = "C:\Miniconda\envs\.."
path = "C:\Miniconda\envs\out\.."
# iterate through the names of contents of the folder
for image_path in os.listdir[path]:
# create the full input path and read the file
input_path = os.path.join[path, image_path]
image_to_rotate = ndimage.imread[input_path]
# rotate the image
rotated = ndimage.rotate[image_to_rotate, 45]
# create full output path, 'example.jpg'
# becomes 'rotate_example.jpg', save the file to disk
fullpath = os.path.join[outPath, 'rotated_'+image_path]
misc.imsave[fullpath, rotated]
if __name__ == '__main__':
main[]
Tái bút: Cách lặp này thông qua nội dung của thư mục chỉ hoạt động nếu chỉ có các tệp trong thư mục và không có thư mục phụ. Os.ListDir [đường dẫn] sẽ trả về tên của bất kỳ tệp nào cũng như các thư mục con.
Bạn có thể tìm hiểu làm thế nào để chỉ liệt kê các tệp trong một thư mục từ bài đăng này: Cách liệt kê tất cả các tệp của một thư mục?
