Any way to record and classify navigation data automatically

Hi, all. Nearly all privacy friendly navigation maps are based on the open street map data. I know we can contribute to those maps manually. However, there are many complaints about missing data in some cities. For instance, I came across a few cities where speed limits are non-existent. So, it’s almost impossible to collect and enter that data manually.

I am wondering if there is any way or software that can automatically recognise road signs from camera recordings and convert this data into an appropriate format that can be imported into openstreetmaps.
