问题
Is there any way to constrain google cloud vision, especially for type TEXT_DETECTION to only recognize digits? I think it will greatly improve my result.
I cannot find any result or hint on the internet at all. Any help is appreciated.

Currently we are unable to constrain by numbers alone. HAve you tried the updated response stream with granular polyboxes to see if this is still an issue?
