使用Python抓取google街景照片

Google map 提供Google Street View Image API让我们使用。

在：https://developers.google.com/maps/documentation/streetview/

下图是一些街景照片的参数信息。

size：图片尺寸

location：经纬度

heading：朝向角度

pitch：旋转角度

key:自己的API_KEY

下面的URL则是获得街景图片的URL，将上面参数拼在一起即可：

url = "https://maps.googleapis.com/maps/api/streetview?size=600x300&location=46.414382,10.013988&heading=151.78&pitch=-0.76&key="#你的KEY"

1. 首先要建一个项目，获取YOUR_API_KEY

2.按照url的格式进行构造

3.使用rullib2的方法下载并保存图片

# _*_ coding: utf-8 _*_
__author__ = 'Administrator'

import urllib2
import threading
from optparse import OptionParser
from bs4 import BeautifulSoup
import sys
import re
import urlparse
import Queue
import hashlib

def download(url, name):
	path = "C:\\Users\\Administrator\\Desktop\\GPS"
	#url = "http://pic2.sc.chinaz.com/files/pic/pic9/201309/apic520.jpg"
	#url = "https://maps.googleapis.com/maps/api/streetview?size=600x300&location=46.414382,10.013988&heading=151.78&pitch=-0.76&key="#你的KEY"

	#保存文件时候注意类型要匹配，如要保存的图片为jpg，则打开的文件的名称必须是jpg格式，否则会产生无效图片
	conn = urllib2.urlopen(url)
	f = open(name, 'wb')
	f.write(conn.read())
	f.close()
	print('Pic Saved!')
fp = open("C:\\Users\\Administrator\\Desktop\\GPS\\paris.txt", "r")

for line in fp.readlines():
	line =  (lambda x: x[11:-11])(line)
	zu = line.split('_')
	jin = zu[0]
	wei = zu[1]
	heading = zu[2]
	name = "C:\\Users\\Administrator\\Desktop\\GPS\\paris_sub\\" + jin + "_" + wei + "_" + heading + "_-004.JPG"
	url = "https://maps.googleapis.com/maps/api/streetview?size=936x537&location=" + jin + "," + wei + "&heading=" +heading + "&pitch=-004&key="#你的KEY"
	#print zu
	print name
	#print url
	download(url, name)

fp.close()
