這篇文章主要為大家詳細介紹了python利用百度AI實現(xiàn)文字識別，主要涉及通用文字識別、網(wǎng)絡(luò)圖片文字識別、身份證識別等文字識別功能，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文為大家分享了python實現(xiàn)文字識別功能大全，供大家參考，具體內(nèi)容如下

1.通用文字識別

# -*- coding: UTF-8 -*-
from aip import AipOcr
 
# 定義常量
APP_ID = '11352343'
API_KEY = 'Nd5Z1NkGoLDvHwBnD2bFLpCE'
SECRET_KEY = 'A9FsnnPj1Ys2Gof70SNgYo23hKOIK8Os'
 
# 初始化AipFace對象
aipOcr = AipOcr(APP_ID, API_KEY, SECRET_KEY)
 
# 讀取圖片
filePath = "test3.png"
 
def get_file_content(filePath):
 with open(filePath, 'rb') as fp:
 return fp.read()
 
# 定義參數(shù)變量
options = {
 'detect_direction': 'true',
 'language_type': 'CHN_ENG',
}
 
# 調(diào)用通用文字識別接口
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.網(wǎng)絡(luò)圖片文字識別

識別一些網(wǎng)絡(luò)上背景復雜，特殊字體的文字。

# -*- coding: UTF-8 -*-
from aip import AipOcr
 
# 定義常量

API_KEY = 'Nd5Z1NkGoLDvHwBnD2bFLpCE'
SECRET_KEY = 'A9FsnnPj1Ys2Gof70SNgYo23hKOIK8Os'
 
# 初始化AipFace對象
aipOcr = AipOcr(APP_ID, API_KEY, SECRET_KEY)
 
# 讀取圖片
filePath = "2-5.jpg"
 
def get_file_content(filePath):
 with open(filePath, 'rb') as fp:
 return fp.read()
 
options={}
options["detect_direction"] = "true" #檢測朝向
options["detect_language"] = "true" #檢測語言
 
result= aipOcr.webImage(get_file_content(filePath),options)
print(result)
for i in range(len(result['words_result'])):
 print(result['words_result'][i]['words'])

SECRET_KEY = 'A9FsnnPj1Ys2Gof70SNgYo23hKOIK8Os'
 
# 初始化AipFace對象
aipOcr = AipOcr(APP_ID, API_KEY, SECRET_KEY)
 
# 讀取圖片
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" #檢測朝向
options["detect_risk"] = "true"
#是否開啟身份證風險類型(身份證復印件、臨時身份證、身份證翻拍、修改過的身份證)功能，默認不開啟
 
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'])

4.銀行卡識別

識別銀行卡并返回卡號和發(fā)卡行。

# -*- coding: UTF-8 -*-
from aip import AipOcr
 
# 定義常量
APP_ID = '11352343'
API_KEY = 'Nd5Z1NkGoLDvHwBnD2bFLpCE'
SECRET_KEY = 'A9FsnnPj1Ys2Gof70SNgYo23hKOIK8Os'
 
# 初始化AipFace對象
aipOcr = AipOcr(APP_ID, API_KEY, SECRET_KEY)
 
# 讀取圖片
filePath = "2-7.jpeg"
 
def get_file_content(filePath):
 with open(filePath, 'rb') as fp:
 return fp.read()
 
options={}
 
result=aipOcr.bankcard(get_file_content(filePath),options)
print(result)
#bank_card_type 銀行卡類型，0:不能識別; 1: 借記卡; 2: 信用卡
for key in result['result']:
 print(key+':'+str(result['result'][key]))

 return fp.read()
 
options={}
options["multi_detect"] = "true"

result= aipOcr.licensePlate(get_file_content(filePath),options)
 
for i in range(len(result['words_result'])):
 print(result['words_result'][i]['color']+' '+result['words_result'][i]['number'])
