准备工具

pip3 install PIL pip3 install opencv-python pip3 install numpy 谷歌驱动

建议指定清华源下载速度会更快点

使用方法 : pip3 install opencv-python -i https://pypi.tuna.tsinghua.edu.cn/simple/opencv-python/

前言

本篇文章采用的是cv2的Canny边缘检测算法进行图像识别匹配。

Canny边缘检测算法参考链接:https://www.jb51.net/article/185336.htm

具体使用的是Canny的matchTemplate方法进行模糊匹配,匹配方法用CV_TM_CCOEFF_NORMED归一化相关系数匹配。得出的max_loc就是匹配出来的位置信息。从而达到位置的距离。

难点

由于图像采用放大的效果匹配出的距离偏大,难以把真实距离,并存在误差。 由于哔哩哔哩滑块验证进一步采取做了措施,如果滑动时间过短,会导致验证登入失败。所以我这里采用变速的方法,在相同时间内滑动不同的距离。 误差的存在是必不可少的,有时会导致验证失败,这都是正常现象。

流程

1.实例化谷歌浏览器 ,并打开哔哩哔哩登入页面。

2.点击登陆,弹出滑动验证框。

3.全屏截图、后按照尺寸裁剪各两张。

5.模糊匹配两张图片,从而获取匹配结果以及位置信息 。

6.将位置信息与页面上的位移距离转化,并尽可能少的减少误差 。

7.变速的拖动滑块到指定位置,从而达到模拟登入。
