本文介绍如何使用Python调用百度AI开放平台的OCR接口，实现通用文字、网络图片、身份证、银行卡、驾驶证、行驶证、车牌及营业执照等多种场景的文字识别功能。包含完整的代码示例、参数配置及结果解析，帮助开发者快速集成文字识别能力。

本文整理了基于Python调用百度AI接口实现各类文字识别功能的完整方案，供开发者参考使用。

1. 通用文字识别

# -*- coding: UTF-8 -*-
from aip import AipOcr
 
# 定义常量
APP_ID = '11352343'
API_KEY = 'Nd5Z1NkGoLDvHwBnD2bFLpCE'
SECRET_KEY = 'A9FsnnPj1Ys2Gof70SNgYo23hKOIK8Os'
 
# 初始化AipFace对象
aipOcr = AipOcr(APP_ID, API_KEY, SECRET_KEY)
 
# 读取图片
filePath = "test3.png"
 
def get_file_content(filePath):
 with open(filePath, 'rb') as fp:
 return fp.read()
 
# 定义参数变量
options = {
 'detect_direction': 'true',
 'language_type': 'CHN_ENG',
}
 
# 调用通用文字识别接口
result = aipOcr.basicGeneral(get_file_content(filePath), options)
print(result)
words_result=result['words_result']
for i in range(len(words_result)):
 print(words_result[i]['words'])

2. 网络图片文字识别

该功能专门用于识别背景复杂或字体特殊的网络图片中的文字内容。

# -*- coding: UTF-8 -*-
from aip import AipOcr

# 初始化AipFace对象
aipOcr = AipOcr(APP_ID, API_KEY, SECRET_KEY)
 
# 读取图片
filePath = "2-5.jpg"
 
def get_file_content(filePath):
 with open(filePath, 'rb') as fp:
 return fp.read()
 
options={}
options["detect_direction"] = "true" #检测朝向
options["detect_language"] = "true" #检测语言
 
result= aipOcr.webImage(get_file_content(filePath),options)

SECRET_KEY = 'A9FsnnPj1Ys2Gof70SNgYo23hKOIK8Os'
 
# 初始化AipFace对象
aipOcr = AipOcr(APP_ID, API_KEY, SECRET_KEY)
 
# 读取图片
filePath1 = "2-6-2.jpg" #正面
filePath2 = "2-6-1.jpg" #背面
def get_file_content(filePath):
 with open(filePath, 'rb') as fp:
 return fp.read()
 
options={}
options["detect_direction"] = "true" #检测朝向
options["detect_risk"] = "true"
#是否开启身份证风险类型(身份证复印件、临时身份证、身份证翻拍、修改过的身份证)功能，默认不开启
 
result1= aipOcr.idcard(get_file_content(filePath1),'front',options)
result2= aipOcr.idcard(get_file_content(filePath2),'back',options)
print(result1)
print(result2)
for key in result1['words_result'].keys():
 print(key+':'+result1['words_result'][key]['words'])
 
for key in result2['words_result'].keys():
 print(key+':'+result2['words_result'][key]['words'])

# 初始化AipFace对象
aipOcr = AipOcr(APP_ID, API_KEY, SECRET_KEY)
 
# 读取图片
filePath = "2-7.jpeg"
 
def get_file_content(filePath):
 with open(filePath, 'rb') as fp:
 return fp.read()
