“不支持的图像对象，使用Tesseract

Posted 2023-01-05

我正在使用Tesseract和Python从图像中构建字符标识符。

这是我的代码：

from PIL import Image
import pytesseract as pyt
     
image_file = 'location'
im = Image.open(image_file)
text = pyt.image_to_string(image_file)
print (text)

执行该程序时出现以下错误：

TypeError：不支持的图像对象

谁能解决这个问题？

答案

the error i am getting is as follows
Traceback (most recent call last):

TypeError: Unsupported image object

另一答案

以下是我的代码：

    import cv2
    import numpy as np
    from PIL import Image
    import pytesseract
    print("hello")
    image = cv2.imread('E:\\OCRimages\\mydrive.jpeg')
    print(image)
    gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)
    print(gray)
    a = cv2.imshow('gray',gray)
    print('done')
    b= pytesseract.image_to_string(a)    
    print(b)
