Read speed limit signs using Cam - Page 2

If your camera is placed behind the inside mirror, and pointing fairly stright forward with a bit of zoom. The pictures would be much better, than captured from an angle.
Speed signs is allways in about the same height, so one can focuse on one sertaint area of the image, narrowing down the bit-stream.

I have no idea of how I would make this cross platform since the original code for the tollroad system is written in delphi and my system will be written in C#

I dont think cross platform is important. It would be nice but mose CarPC owners are running Windows.

I like the idea, there are lots of time when I'm in new placed I end up wondering if I am speeding because I'm not paying attention. Subscribed.

This would be good way of recording the speed limits for certain stretches of roads. When combined with a set of GPS traces, it could add speed limit data.

In some distant future, it could record the speed of the car, compare it to the speed limit, and relay some kind of speed index (i.e. 80% of speed limit) to a server so others could see whether the route was congested. Eh, obviously it would simply report 100% if you were traveling faster than the limit!

In any case, it is a cool first step towards using a car PC for something different and unusual.

That's funny, I'm writing an app in C# for Linux as we speak.

Thunderstick, what language is it written in? I mentioned before I wouldn't mind helping make it work on everything. If it's any .NET language, just don't hardcode any C:\ paths and make the video device configurable. Then it will work on Mac/Linux without any code changes.

Most people use Windows on their carpc because most software for carpc's are written for windows. It's the chicken and the egg all the way to the supermarket. The more apps like this that aren't frontend plugins that are written crossplatform the more freedom everyone will have choosing the platform that works best for them.

How many people in this forum would be running Linux if only their favorite Navigation App, XM plugin, XYZ app ran on Linux also? I know for a fact there's a lot. There's plenty of people who aren't afraid of the unknown and are willing to try something new if they see the benefit and value from doing so.

Ups...
So there's no problem in writing C# for linux?

To be honest, I thought that everything stoped beeing crossplatformed as long as it used .NET *blush*

[Raises hand]

While Linux is still a somewhat opaque black box to me, my experiments with it have been encouraging and it's been stable and fast for me.

For what my inexperience is worth, I was thinking of what Bugbyte mentioned...record where the speed limit signs are and set them up to be recorded by GPS so you could just have the information as a sort-of Place of Interest in the POI DB. Then it could be a small icon in your frontend that could tell you the speed limit...in case you forget, like I often do.

If you take a look at my Speed Zone plug in for RR, I am planning to do something simlar with the speed limit information gathered. Currently in the pluggin you have to manually enter speed limits. I thought if I could figure out a way to read speed limit signs efficiently I could have it automatically save the speed limit information thus making easier for the user of Speed Zone to safely drive and effectively monitor the drivers speed and position.

if your gonna make an app like that i think it should have a professional looing gui. nothing too overkill with skins and metallic colors just the regular windows back and foreground. just putting in my 2 cents cause i seen some pretty jassed up cheesy lilliput front ends that made me skin sick ahahah

bowser22 · 07-06-2009, 03:07 PM

i feel like i killed the thread...no posts in days

Crinos · 07-06-2009, 04:04 PM

Lol... You've sentenced to view 999 episodes of "The L Word" xP

If I ever come arround to make anything like this... I will try my very best to make it crossplatform and skinnable.
