Speed detection

Post by crizcook »

Hi Everyone
I am interested in tracking how quickly something passes right to left from a video feed, and if greater than a particular speed, to trigger.

You guessed it, for basic car speed detection - i live in a little village that is used as a race track at night. Initially it would be good to have just an alert of capturing the image of the car. I would move onto apnr / posting to facebook as the next stage.

Back to detection, any ideas?

BI out-of-the-box cannot do this. Not sure about the AI option.

Same issue where I am. This is what I had thought of...

- Putting two white marks in the street (using the chalk water based spray). , 100' apart - or a known distance. Probably illegal, which is why I havn't done it.
If there are marks in the road... cracks/manhole covers/marking... use those.

- Using BI, you could time the marks where the front/read tire touches the marks, noting the timing.

- using the timings, you can easily calculate the speed.


Kind of weird. But, I think it would work. The Sherriff dept. here in Minnesota usig this meathod with helicopters on dome of the freeways with markings 1/10 to 1/3 mile apart.
