================================================  
Sorry 服务器欠费已停用，现给出爬虫代码及切图代写  
================================================  
1、爬取验证图片

#coding:u8
    from selenium import webdriver
    from selenium.webdriver.common.keys import Keys
    from selenium.webdriver.common.by import By
    from selenium.webdriver.support.ui import WebDriverWait
    from selenium.webdriver.support import expected_conditions as EC
    from selenium.webdriver.common.action_chains import ActionChains
    import requests
    import base64
    import re
    import time
    import os
    import _thread
    
    
    def getImage(name):
    	login_url="https://kyfw.12306.cn/otn/resources/login.html"
    	driver = webdriver.Chrome()
    	driver.get(login_url)
    	count=0
    	while 1:
    		count+=1
    		if not os.path.exists(name):
    			os.mkdir(name)		
    		driver.find_element_by_class_name("login-hd-account").click()
    		try:	
    			time.sleep(2)
    			img_element =WebDriverWait(driver, 100).until(
    				EC.presence_of_element_located((By.ID, "J-loginImg"))
    			)
    			base64_str=img_element.get_attribute("src").split(",")[-1]
    			imgdata=base64.b64decode(base64_str)
    			pname=os.path.join("verify",name+str(count)+".jpg")
    			print(pname)
    			with open(pname,'wb') as file:
    				file.write(imgdata)
    		except Exception as e:
    			print(u"网络开小差,请稍后尝试")	
    		
    		driver.refresh()
    print("start")
    try:
    	_thread.start_new_thread(getImage,("THREAD-1",))
    	_thread.start_new_thread(getImage,("THREAD-2",))	
    	_thread.start_new_thread(getImage,("THREAD-3",))
    	_thread.start_new_thread(getImage,("THREAD-4",))	
    except Exception as e:
    	print("启动失败")
    while 1:
       pass

爬虫开了4个线程，将验证图片放入4个文件夹中，请自行归并到一个文件夹下，供切图使用  
2、切图

#coding:u8
    import cv2
    import os
    if not os.path.exists("12306_dataset_obj"):
    	os.mkdir("12306_dataset_obj")
    if not os.path.exists("12306_dataset_word"):
    	os.mkdir("12306_dataset_word")	
    for batch,file_name in enumerate(os.listdir("verify")):
    
    	print(u"处理第{:>9}张图".format(batch+1))
    	im=cv2.imread("verify/{}".format(file_name),1)
    
    	patch=[
    		im[0:25,120:290],
    		im[41:108,5:72],
    		im[41:108,77:144],
    		im[41:108,149:216],
    		im[41:108,221:288],
    		im[113:180,5:72],
    		im[113:180,77:144],
    		im[113:180,149:216],
    		im[113:180,221:288]
    		]
    	
    	for i,item in enumerate(patch):
    		if i is not 0:
    			cv2.imwrite("12306_dataset_obj/{}.jpg".format(batch*8+i),item)
    		else:
    			cv2.imwrite("12306_dataset_word/{}.jpg".format(batch+1),item)
