import tesserocr
from PIL import Image
ima = Image.open('1.png')
image=ima.resize((480,200),Image.ANTIALIAS)
image = image.convert('L')
這個(gè)是二值化閾值
threshold = 160
table = []
for i in range(256):
if i < threshold:
table.append(0)
else:
table.append(1)
通過(guò)表格轉(zhuǎn)換成二進(jìn)制圖片，1的作用是白色，不然就全部黑色了
image = image.point(table, "1")
print(tesserocr.image_to_text(image)[:5]) # print ocr text from image
