导语
哈喽!boys and girls 我是每天疯狂赶代码的木木子~
今天带大家来点儿好玩儿的东西,我想你们肯定是喜欢的!
上面这个大家都认识吧
对,就是字符动画啦,之前也是不是再那个旮旯里面看见过,但是还没上手自己试的。
小编给大家先试试效果了,效果也是真不错,趣味性蛮强滴 推荐指数5颗星,大家都开始动手
燥起来吧~
那么如何将视频动画转成字符画呢?今天就来教大家怎么转换,非常简单,今天教大家制作的
这款工具就能一键转换!
正文
一、准备中
1)素材的话可以自己找一小段视频的哈。
2)环境安装
本文用到的环境如下:Python3、Pycharm、numpy、cv2以及部分自带模块。
模块安装:
pip install -i https://pypi.douban.com/simple/ +模块名
二、原理简介
1)视频转为一帧帧的图片这个利用OpenCV就可以实现了。
2)**将每帧图片转为字符画,**原理是根据图片的像素值确定每个像素点用什么字符。
3)按顺序播放字符画即可。
三、代码演示
