python图像识别

1. 获取验证码图片
首先，我们需要发送HTTP请求来获取验证码的背景图和滑块图。

python

import requests
import shutil

def fetch_captcha_images():
    response = requests.get('https://example.com/captcha')
    data = response.json()
    
    bg_image_response = requests.get(data['bg'])
    slider_image_response = requests.get(data['slider'])
    
    with open('bg.jpg', 'wb') as f:
        f.write(bg_image_response.content)
        
    with open('slider.png', 'wb') as f:
        f.write(slider_image_response.content)

    return 'bg.jpg', 'slider.png'
2. 处理图片并识别滑块位置
我们使用OpenCV库处理图片，并识别出滑块需要移动的位置。

python

import cv2

def detect_slider_position(bg_path, slider_path):
    bg = cv2.imread(bg_path, 0)
    slider = cv2.imread(slider_path, 0)

    result =
