图像到文本-Pytesseract与Windows上的数字作斗争 [英] Image to Text - Pytesseract struggles with digits on windows

问题描述

我正在尝试为ML项目实时预处理游戏框架.我想从框架中提取数字，所以我选择了Pytesseract，因为它在文本上看起来相当不错.虽然，无论我做的文字多么清晰，它都无法正确阅读.我的代码如下:

I'm trying to preprocess frames of a game in real-time for a ML project. I want to extract numbers from the frame, so I chose Pytesseract, since it looked quite good with text. Though, no matter how clear I make the text, it won't read it correctly. My code looks like this:

section = process_screen(screen_image)[1]
pixels = rgb_to_bw(section) #Makes the image grayscale
pixels[pixels < 200] = 0 #Makes all non-white pixels black
tess.image_to_string(pixels)

=> 'ye ml)'

当我未指定我想要数字时，充其量它最多会输出"ye ml)"，而当我输入数字时，它什么也不会输出.

At best it outputs "ye ml)" when I don't specify I want digits, and when I do, it outputs nothing at all.

未经处理的游戏图像如下所示:

The non-processed game image looks like so:

像素"图像如下所示:

The "pixels" image looks like so :

感谢Alex Alex，我反转了图像，并得到了

Thanks to Alex Alex, I inverted the image, and got this

得到"2710"，虽然更好，但仍不完美.

And got "2710", which is better, but still not perfect.

推荐答案

在识别之前必须反转图像.

You must invert the image before recognition.
