这次给大家带来python批量读取图片且存入数据库的实现，python批量读取图片且存入数据库的注意事项有哪些，下面就是实战案例，一起来看一下。
本文实例讲述了Python实现批量读取图片并存入mongodb数据库的方法。分享给大家供大家参考，具体如下：
我的图片放在E:\image\中，然后使用python将图片读取然后，显示一张，存入取一张（可以注释掉显示图片的语句），通过Gridfs的方式存入图片。代码如下：
# --* coding=utf-8 *--
from cStringIO import StringIO
from pymongo import MongoClient
import gridfs
import os
import matplotlib.pyplot as plt
import matplotlib.image as iming
import bson.binary
import numpy as np
if name == 'main':
connect = MongoClient('127.0.0.1', 27017) # 创建连接点
db = connect.mydb
print db.collection_names()
imgput = gridfs.GridFS(db)
dirs = 'G:\image'
files = os.listdir(dirs)
for file in files:
filesname = dirs + '\\' + file
print filesname
imgfile=iming.imread(filesname)
# iming.imsave('s.jpg',imgfile)
# print type(imgfile),imgfile
# imgfile.shape()
plt.imshow(imgfile)
plt.axis('off')
plt.show()
f=file.split('.')
print f
datatmp=open(filesname,'rb')
data=StringIO(datatmp.read())
content=bson.binary.Binary(data.getvalue())
# print content
insertimg=imgput.put(data,content_type=f[1],filename=f[0])
datatmp.close()
