answerSheetScan

因为要当助教,批改答题卡,很无聊,想着能不能做一个识别答题卡的py程序,看了下git上的不少程序没法很符合自己的需求吧,参考了一些别人对答题卡的识别方法,采用的还是python上的opencv写了一个小原型(吐槽一下surface3的垃圾摄像头,不能对焦,设备有限,只能拿手机摄像头作摄像头)。

能用是能用了,不过识别率感人:cry:,填涂和线框重合的时候就没法识别了,这个问题研究了下可以通过识别凸域进行切割,有需要再改改吧,凑活自己能用:slightly_smiling_face:算是做个记录吧,算是菜鸟入门做了一点实际能用的东西。img里面放了一些测试图片。

依赖库:

1.numpy

2.pythonopencv

3.imutils

测试图:image
