Android (OpenCV or alternative) bubble sheet scanner (specific)

Hello,

I need an Android bubble sheet scanner for specific bubble sheet (included)

I tried to do it myself but the bubbles are bit small and close to each other.

The bubble sheet will be printed on A4 paper, and filled with PENCILS (!).

It is possible to modify the bubble sheet (a bit!), like making bubbles a bit bigger, or making the bubbles sections a bit wider.

I would like that every sheet I scan exports an EXCEL file (or similar) with the ID as a name.

Thanks.
