Pi Pico plus camera to read and decode road speed signs?

I was just sitting doing nothing much and I suddenly had a thought. Could something like a Raspberry Pi Pico recognise/decode road speed signs and display the speed limit on a small display. It would make an interesting little, though expensive, project. Time to do some reading and watch some videos.

Just my off the top of my head answer. That might be fairly difficult, I haven't seen any camera lens that would produce a big enough image to be used, but maybe. There are also issues with glare, window curvature, dirty car windows. Many moons ago (50 yrs) I wrote some code to read text but in a tightly controlled environment. I do not remember a thing about it. I am curious though to hear how you do, keep us informed.

It is considered poor judgement to traverse a chasm in 2 leaps.

It may not be practical as there is no homogeneity in the design of road signs. Formats vary from area to area.

Besides, it might interfere with your texting as you drive 🙂

Highly possible, and entirely implementable, IMO!

There are standard image libraries available to help with this, and then there are AI libraries to do the same.

It all depends on how much time you're willing to put into such kind of project, and how far you want to go.

Cheers
