如何在Python中下载谷歌图像搜索结果

使用 Google Custom Search 为了你想要实现的目标。 看见 @i08英寸 的答案 Python - Download Images from google Image search? 它有很好的描述、脚本示例和库参考。

请确保首先安装icrawler库,然后使用。

pip install icrawler

from icrawler.builtin import GoogleImageCrawler
google_Crawler = GoogleImageCrawler(storage = {'root_dir': r'write the name of the directory you want to save to here'})
google_Crawler.crawl(keyword = 'sad human faces', max_num = 800)

要使用Selenium从Google图像搜索中下载任意数量的图像:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import os
import json
import urllib2
import sys
import time

# adding path to geckodriver to the OS environment variable
# assuming that it is stored at the same path as this script
os.environ["PATH"] += os.pathsep + os.getcwd()
download_path = "dataset/"

def main():
    searchtext = sys.argv[1] # the search query
    num_requested = int(sys.argv[2]) # number of images to download
    number_of_scrolls = num_requested / 400 + 1 
    # number_of_scrolls * 400 images will be opened in the browser

    if not os.path.exists(download_path + searchtext.replace(" ", "_")):
        os.makedirs(download_path + searchtext.replace(" ", "_"))

    url = "https://www.google.co.in/search?q="+searchtext+"&source=lnms&tbm=isch"
    driver = webdriver.Firefox()
    driver.get(url)

    headers = {}
    headers['User-Agent'] = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36"
    extensions = {"jpg", "jpeg", "png", "gif"}
    img_count = 0
    downloaded_img_count = 0

    for _ in xrange(number_of_scrolls):
        for __ in xrange(10):
            # multiple scrolls needed to show all 400 images
            driver.execute_script("window.scrollBy(0, 1000000)")
            time.sleep(0.2)
        # to load next 400 images
        time.sleep(0.5)
        try:
            driver.find_element_by_xpath("//input[@value='Show more results']").click()
        except Exception as e:
            print "Less images found:", e
            break

    # imges = driver.find_elements_by_xpath('//div[@class="rg_meta"]') # not working anymore
    imges = driver.find_elements_by_xpath('//div[contains(@class,"rg_meta")]')
    print "Total images:", len(imges), "\n"
    for img in imges:
        img_count += 1
        img_url = json.loads(img.get_attribute('innerHTML'))["ou"]
        img_type = json.loads(img.get_attribute('innerHTML'))["ity"]
        print "Downloading image", img_count, ": ", img_url
        try:
            if img_type not in extensions:
                img_type = "jpg"
            req = urllib2.Request(img_url, headers=headers)
            raw_img = urllib2.urlopen(req).read()
            f = open(download_path+searchtext.replace(" ", "_")+"/"+str(downloaded_img_count)+"."+img_type, "wb")
            f.write(raw_img)
            f.close
            downloaded_img_count += 1
        except Exception as e:
            print "Download failed:", e
        finally:
            print
        if downloaded_img_count >= num_requested:
            break

    print "Total downloaded: ", downloaded_img_count, "/", img_count
    driver.quit()

if __name__ == "__main__":
    main()

对Ravi Hirani的答案稍加改进,最简单的方法是:

from icrawler.builtin import GoogleImageCrawler

google_crawler = GoogleImageCrawler(storage={'root_dir': 'D:\\projects\\data core\\helmet detection\\images'})
google_crawler.crawl(keyword='cat', max_num=100)

这个怎么样?

它允许您下载数百张图片,并有大量过滤器可供选择,以定制您的搜索

如果你愿意 每个关键字下载100多张图片 ,则需要安装“selenium”和“chromedriver”。

如果您安装了pip库或运行安装程序。py文件,Selenium将自动安装在您的计算机上。您的机器上还需要Chrome浏览器。对于chromedriver:

根据您的操作系统下载正确的chromedriver。

在Windows或MAC上,如果由于某种原因chromedriver给您带来了麻烦,请将其下载到当前目录下并运行该命令。

然而,在windows上,chromedriver的路径必须以以下格式给出:

C: \complete\path\到\chromedriver.exe

在Linux上,如果您在安装google chrome浏览器时遇到问题,请参阅本CentOS或Amazon Linux指南或Ubuntu指南

对于所有操作系统,您必须使用“--chromedriver”或“-cd”参数来指定您在计算机中下载的chromeddriver的路径。

我一直在使用这个脚本从谷歌搜索下载图片,我一直在用它们训练我的分类器 下面的代码可以下载与查询相关的100个图像

from bs4 import BeautifulSoup
import requests
import re
import urllib2
import os
import cookielib
import json

def get_soup(url,header):
    return BeautifulSoup(urllib2.urlopen(urllib2.Request(url,headers=header)),'html.parser')


query = raw_input("query image")# you can change the query for the image  here
image_type="ActiOn"
query= query.split()
query='+'.join(query)
url="https://www.google.co.in/search?q="+query+"&source=lnms&tbm=isch"
print url
#add the directory for your image here
DIR="Pictures"
header={'User-Agent':"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/43.0.2357.134 Safari/537.36"
}
soup = get_soup(url,header)


ActualImages=[]# contains the link for Large original images, type of  image
for a in soup.find_all("div",{"class":"rg_meta"}):
    link , Type =json.loads(a.text)["ou"]  ,json.loads(a.text)["ity"]
    ActualImages.append((link,Type))

print  "there are total" , len(ActualImages),"images"

if not os.path.exists(DIR):
            os.mkdir(DIR)
DIR = os.path.join(DIR, query.split()[0])

if not os.path.exists(DIR):
            os.mkdir(DIR)
###print images
for i , (img , Type) in enumerate( ActualImages):
    try:
        req = urllib2.Request(img, headers={'User-Agent' : header})
        raw_img = urllib2.urlopen(req).read()

        cntr = len([i for i in os.listdir(DIR) if image_type in i]) + 1
        print cntr
        if len(Type)==0:
            f = open(os.path.join(DIR , image_type + "_"+ str(cntr)+".jpg"), 'wb')
        else :
            f = open(os.path.join(DIR , image_type + "_"+ str(cntr)+"."+Type), 'wb')


        f.write(raw_img)
        f.close()
    except Exception as e:
        print "could not load : "+img
        print e

我在努力 this library 既可以用作命令行工具,也可以用作python库。它有很多论点来寻找具有不同标准的图像。

这些示例取自其文档,用于将其用作python库:

from google_images_download import google_images_download   #importing the library

response = google_images_download.googleimagesdownload()   #class instantiation

arguments = {"keywords":"Polar bears,baloons,Beaches","limit":20,"print_urls":True}   #creating list of arguments
paths = response.download(arguments)   #passing the arguments to the function
print(paths)   #printing absolute paths of the downloaded images

或作为命令行工具,如下所示:

$ googleimagesdownload --k "car" -sk 'red,blue,white' -l 10

您可以使用安装 pip install google_images_download

这个问题的一个简单解决方案是安装一个名为 google_images_download

pip install google_images_download

使用此python代码

from google_images_download import google_images_download  

response = google_images_download.googleimagesdownload()
keywords = "apple fruit"
arguments = {"keywords":keywords,"limit":20,"print_urls":True}
paths = response.download(arguments)
print(paths)

调整限制以控制要下载的图像数量

但有些图像可能已损坏,因此无法打开

更改 keywords 获取所需输出的字符串

您需要使用自定义搜索API。有一个方便的 explorer 在这里我使用urllib2。您还需要从开发人员控制台为应用程序创建API密钥。

我试过很多代码,但没有一个适合我。我在这里发布我的工作代码。希望它能帮助其他人。

我使用的是Python 3.6版 icrawler

首先,您需要下载 icrawler 在您的系统中。

然后运行下面的代码。

from icrawler.examples import GoogleImageCrawler
google_crawler = GoogleImageCrawler()
google_crawler.crawl(keyword='krishna', max_num=100)

代替 keyword krishna 与您想要的文本。

笔记 :-下载的图像需要路径。现在我使用了脚本所在的相同目录。您可以通过以下代码设置自定义目录。

google_crawler = GoogleImageCrawler('path_to_your_folder')
