python mass search engine image


python Image crawler package

Recently, when doing some image classification tasks , To expand our dataset , We need to crawl under the search engine for additional images to expand our training set . It's really hard to do artificial intelligence , I'm still a reptile . Of course, there are many on the Internet python The crawler tool for writing , Of course , If you use it more, you will know , These crawler tools can not be used for multi keyword crawler, or they can not be used , Or it will be stopped after being detected by the website , Finally found a very easy to use python Image crawler Library icrawler, You can go straight through pip Installation , It can be done in a few lines of code , Don't be too cool .
Don't talk much , Attach installation commands :

pip install icrawler

Here is my crawler code :

from icrawler.builtin import BaiduImageCrawler
from icrawler.builtin import BingImageCrawler
from icrawler.builtin import GoogleImageCrawler
# Need crawler keywords 
list_word = [' smoking Pedestrians ',' smoking Pedestrians ',' answer the phone Pedestrians ',' Make a phone call Pedestrians ', ' Play with the smarthphone Pedestrians ']
for word in list_word:
#bing Reptiles 
# Save the path 
bing_storage = {'root_dir': 'bing\\'+word}
# From top to bottom is the number of parser threads , Number of download threads , And the save path set above 
bing_crawler = BingImageCrawler(parser_threads=2,
downloader_threads=4,
storage=bing_storage)
# Start crawling , keyword + graphics 
bing_crawler.crawl(keyword=word,
max_num=2000)
# Baidu crawler 
# baidu_storage = {'root_dir': 'baidu\\' + word}
# baidu_crawler = BaiduImageCrawler(parser_threads=2,
# downloader_threads=4,
# storage=baidu_storage)
# baidu_crawler.crawl(keyword=word,
# max_num=2000)
# google Reptiles 
# google_storage = {'root_dir': '‘google\\' + word}
# google_crawler = GoogleImageCrawler(parser_threads=4,
# downloader_threads=4,
# storage=google_storage)
# google_crawler.crawl(keyword=word,
# max_num=2000)

This crawler library can implement multithreading , Multiple search engines ( Baidu 、 Bing Ying 、 Google ) The reptiles of , Of course, Google crawlers need ladders . Here's a Bing based crawler , Baidu and Google Code is also below , It's just blocked by me , Of course, you can open all three at the same time ! In this way python The crawler library doesn't work very well .
Please give me a compliment if you like it
