從存檔中打開圖像並加載到 cv2

Question

我正在嘗試將存檔中的圖像加載到 CV2 中。

我的文件語句是存檔路徑。

file = "Final/small_img.zip"

接下來，我嘗試循環打開存檔一個圖像：

#import the zipfile as archive
with zipfile.ZipFile(file, 'r') as archive:
    
    #get the filename of all files in the archive and append to a list
    archive_file = archive.namelist()
    
    #Test initial program with a single image
    news = archive.open(archive_file[0])
    pic = cv.imread(news)
    #pic = Image.open(news)

我可以使用 Image.open(news) 使用 PIL 打開圖像，但由於我不會同時運行 pytesseract 和 haarcascade，因此我需要數組中的圖像。

我發現了我的問題，我忘記導入 numpy ....

#import the zipfile as archive
with zipfile.ZipFile(file, 'r') as archive:
    #get the filename of all files in the archive and append to a list
    archive_file = archive.namelist()

    # Test initial program with a single image
    news = archive.open(archive_file[0])
    pic = Image.open(news)
    pic_arr = np.array(pic)

    #Test tesseract
    #im1 = pytesseract.image_to_boxes(pic)
    im1 = pytesseract.image_to_string(pic)
    faces = face_cascade.detectMultiScale(pic_arr)
    print(f"{len(faces)} faces detected in the image.")
