python如何破解绕开滑动拼图验证码？

使用pyppeteer获取滑块图片并通过cv2来进行图片处理算出拼凑位置的像素值，最后模拟用户进行滑动完成验证码，完整的代码如下：

#!/usr/local/python3/bin/python3
# -*- coding: utf-8 -*
from pyppeteer import launch
import asyncio
import time
import json
import random
import cv2

def get_track(length):
    list = []
    x = random.randint(1,10)
    while length:
        list.append(x)
        length -= x
        if length > 0 and length <= 5:
            break
        elif 5 < length < 25:
            x = random.randint(2,length)
        else:
            x = random.randint(5,25)
    for i in range(length):
        list.append(1)
    return list

def change_size( file):
    image = cv2.imread(file, 1)  # 读取图片 image_name应该是变量
    img = cv2.medianBlur(image, 5)  # 中值滤波，去除黑色边际中可能含有的噪声干扰
    b = cv2.threshold(img, 15, 255, cv2.THRESH_BINARY)  # 调整裁剪效果
    binary_image = b[1]  # 二值图--具有三通道
    binary_image = cv2.cvtColor(binary_image, cv2.COLOR_BGR2GRAY)
    x, y = binary_image.shape
    edges_x = []
    edges_y = []
    for i in range(x):
        for j in range(y):
            if binary_image[j] == 255:
                edges_x.append(i)
                edges_y.append(j)

    left = min(edges_x)  # 左边界
    right = max(edges_x)  # 右边界
    width = right - left  # 宽度
    bottom = min(edges_y)  # 底部
    top = max(edges_y)  # 顶部
    height = top - bottom  # 高度
    pre1_picture = image[left:left + width, bottom:bottom + height]  # 图片截取
    return pre1_picture  # 返回图片数据
async def main(url):
    try:
        browser = await launch({'headless':False, 'dumpio': True, 'autoClose': False, 'args': ['--no-sandbox', '--window-size=1366,850']})
        page = await browser.newPage()
        await page.evaluateOnNewDocument('''() => {delete navigator.__proto__.webdriver;}''')
        await page.evaluateOnNewDocument('''() => {Object.defineProperty(navigator, 'webdriver', {get: () => undefined,});}''')
        await page.evaluateOnNewDocument('''() =>{ Object.defineProperty(navigator, 'languages', { get: () => ['en-CN', 'cn'] }); }''')
