1.使用pytesseract和PIL库
（1）安装pytesseract和PIL库：pycharm->settings->project interpreter
（2）安装识别引擎tesseract-ocr：点击打开链接
from PIL import Image import pytesseract text=pytesseract.image_to_string(Image.open('test3.png'),lang='chi_sim') print(text)但是识别英文和数字效果还可以，识别中文效果较差。
2.利用百度AI提供的python SDK
安装OCR Python SDK：pip install baidu-aip

（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）表格文字识别：# -*- coding: UTF-8 -*- from aip import AipOcr import time # 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 = "1-2.png" def get_file_content(filePath): with open(filePath, 'rb') as fp: return fp.read() options1={} # 调用通用文字识别接口 result1 = aipOcr.tableRecognitionAsync(get_file_content(filePath), options1 ) requestID=result1['result'][0]['request_id'] time.sleep(20) #为了'ret_msg': '已完成' options2 = {} options2["result_type"] = "json" result2=aipOcr.getTableRecognitionResult(requestID,options2) print(result2) str_result=str(result2) begin=str_result.find('word') for i in range(str_result.count('word')): print(str_result[begin+7:str_result.find('"',begin+8)]) begin=str_result.find('word',begin+1)识别出来的结果需要再处理一下。文章来源: 【Python】Python文字识别
