目前仍在測試階段

Dockerfile的Tesseract是最新版，辨識結果會有錯誤
test0.0.3尚在測試新版能否使用

參考

fork origin: https://github.com/otiai10/ocrserver

與原版差異

辨識圖片中井字型或同一排數字0~9位置，標準英文鍵盤排列的26個英文字母位置， 123、abc的手機螢幕鍵盤切換語言位置。

條件限制

test0.0.3版本可辨識圖片中井字型1到9的XY位置，但0需要在7到9的下方，
同水平中不可有重複數字，尚未加入符號的辨識。

目前可辨別錯誤

1. find multiple same or shortage of numbers by y point line
   圖片中鍵盤缺少或其他位置出現，123、456、789的三種數字組合。
2. not found number : 0
   0未被在數字789的底下找到。

TODO

1. 數字鍵盤789底下若有多個0
2. 數字鍵盤未確認井字X軸
3. 數字鍵盤未確認多個井字組合
4. 切換鍵未確認必定出現在左下角區域
