2.代码和测试效果
2.1识别英文图片
代码如下：
from PIL import Image
import pytesseract
path="test2.png"
im=Image.open(path)
text=pytesseract.image_to_string(im)
print(text)test2.png图片如下：
识别效果：
结论：只有第1个字母识别错误
2.2 识别中文图片
代码如下：
from PIL import Image
import pytesseract
path="test4.png"
im=Image.open(path)
text=pytesseract.image_to_string(im,lang='chi_sim')
print(text)test4.png图片如下：
识别效果：
中文识别效果比较差。
