Two ideas

Tune cloud online interface or use the SDK to do development (environment and configure third-party libraries to compile a lot of trouble, of course, these problems can be avoided using python)
Own license plate recognition algorithms (complex)

Baidu cloud began to prepare a text recognition using C ++ SDK to do, find it necessary to prepare curl, jsoncpp and OpenCV, and curl and jsoncpp need to compile a lot of trouble, so switching to a python to do, really smooth and simple.
Install python environment (I use python3.7)

Open the installation package can be installed without the brain. After installing, see if the installation was successful.

cmd

python --version

Baidu Cloud SDK to create applications to download and install

Reference https://cloud.baidu.com/doc/OCR/s/pjwvxzmtc documentation, installation python SDK

View pip version (python own environment, but be aware version)

pip --version

If the version is not appropriate, then the upgrade itself pip

pip install -U pip

AnSo baidu-aip

pip install baidu-aip

Now we are on the Baidu Cloud SDK installed, create applications down

Creating an application

Fill out their own

现在我们就创建好了车牌识别的应用，点击应用列表可查看。

这里的APPID、API KEY、Secret Key要在代码中使用。（注意不要泄漏）

编码调接口，实现需求

python代码实现

'''
Statement
1\. using the file
2\. prepare a image path and call func "get_license_plate(filePath)"
3\. you can get a json object
4\. get the info from the pbject
example : 
{
    "log_id": 3583925545,
    "words_result": {
        "color": "blue",
        "number": "苏HS7766"
    }
}
'''

from aip import AipOcr
import json

"""get img"""
def get_file_content(filePath):
    with open(filePath, 'rb') as fp:
        return fp.read()

""" get licsense plate """
def get_license_plate(filePath):
    """ APPID AK SK """
    APP_ID = '********'
    API_KEY = '**************'
    SECRET_KEY = '******************'

    """ create client """
    client = AipOcr(APP_ID, API_KEY, SECRET_KEY)

    image = get_file_content(filePath)

    """ 调用车牌识别 """
    res = client.licensePlate(image)
    return res

""" call example """
str = 'C:\\Users\\***\\Desktop\\big.jpg' """ 照片绝对地址 """
res = get_license_plate(str)
print('车牌号码：' + res['words_result']['number'])
print('车牌颜色：' + res['words_result']['color'])
