一个小需求,实现车牌识别,实现车牌识别算法(复杂)!本篇文章借助百度云来完成,不用闭门造车了。换用了python来做,真的是顺畅简单。
安装python环境(我用python3.7)
python官网下载地址:https://www.python.org/downloads/release/python-374/ 建议直接下载安装版installer(看对系统和位数)
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***Desktopbig.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'])
至此,我们就实现了使用百度云SDK,通过编写python代码调用接口的车牌识别需求。
