Introduction
The latest Python to do OCR text recognition_Baidu source code , now has been updated to the GUI version
installation
I saw the official and found out that there is pip installation. . I looked for the SDK for a long time
Method one pip
pip install baidu-aip
Method two sdk
After downloading the python SDK , decompress it and run the decompressed setup.py
python setup.py install
Create an application, get the key
Open Baidu Cloud, register for real-name authentication,
enter the console, click on text recognition, create an
application, and copy ID + key in the created application
Start to recognize
Text to be recognized
Basic version V0.0.0
# 利用百度OCR在线识别图片文本
from aip import AipOcr
""" 读取图片 """
def get_file_content(filePath):
with open(filePath, 'rb') as fp:
return fp.read()
if __name__ == "__main__":
""" 你的 APPID AK SK """
APP_ID = '你的 App ID'
API_KEY = '你的 Api Key'
SECRET_KEY = '你的 Secret Key'
client = AipOcr(APP_ID, API_KEY, SECRET_KEY)
image = get_file_content('tmp.PNG')
""" 调用通用文字识别, 图片参数为本地图片 """
res = client.basicGeneral(image);
print( res)
For Image, Baidu conditions: image data, base64 encoding, base64 encoding requires no larger than 4M, 15px shortest side at least, the maximum longest side 4096px, support jpg / png / bmp format
basicGeneral () Returns the format interpretation
