下面是代码:
import pytesseract
import cv2
import numpy as np
def get_string(img_path):
img = cv2.imread(img_path)
img = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
kernel = np.ones((1,1), np.uint8)
dilate = cv2.dilate(img, kernel, iterations=1)
erosion = cv2.erode(img, kernel, iterations=1)
cv2.imwrite('removed_noise.jpg', img)
img = cv2.adaptiveThreshold(img, 255, cv2.ADAPTIVE_THRESH_GAUSSIAN_C, cv2.THRESH_BINARY, 11, 2)
cv2.imwrite('thresh.jpg', img)
res = pytesseract.image_to_string('thesh.jpg')
return res
print('Getting string from the image')
print(get_string('quotes.jpg'))

TesseractNotFoundError:未安装tesseract或它不在您的路径中
TesseractNotFoundError: tesseract is not installed or it's not in your path
推荐答案
步骤1:从链接.
第2步:安装后，找到" Tesseract-OCR "文件夹，双击该文件夹并找到 tesseract.exe .
Step 2: After installing find the "Tesseract-OCR" folder, double Click on this folder and find the tesseract.exe.
第3步:找到 tesseract.exe 后，复制文件位置.
Step 3: After finding the tesseract.exe, copy the file location.
第4步:像这样将这个位置传递到您的代码中
Step 4: Pass this location into your code like this
pytesseract.pytesseract.tesseract_cmd = r"C:\Program Files\Tesseract-OCR\tesseract.exe"
注意:C:\ Program Files \ Tesseract-OCR \ tesseract.exe ==您复制的位置
Note: C:\Program Files\Tesseract-OCR\tesseract.exe == your copied location
