Webcam RangeFinder

at 7:25 am. Filed under Computer Hacks, Cool Gadgets, DIY Hacks


DIY Lab has put up some plans that will allow you to use your webcam as a rangefinder. I wonder if the technique used is similar to the golf green distance estimators?

"Convert your webcam into a modern range estimation tool without any hardware. The math is very simple, so this new technique works very well for vision applications that need to run quickly. With a simple height estimation, the program will easily calculate the range to a distant object with high precision. The software will be next upgraded with motion detection."

    Exactly the same as the “golf green distance estimators”. “Simple height estimation”. Why hasn’t anyone thought of this before? This would be a great application for the iPhone. You could be a thousandaire!

    miked, this is the good 2500 years old pythagorean theorem at work. You can accomplish the same result with a ruler and a piece of string, both of known length. It’s an old trick I was taught in the army and should be easy to find on the net.
    Anyway, to get enough precision you always need to have a rough estimate of the subject height. I believe this wasn’t done before on phones probably because of their terrible optics and the resulting distortion that would reduce the calculations precision.

    i meant why hasn’t it been done on a computer before. i understand how it was done.

    I am moved to comment by miked’s first post: “You could be a thousandaire!”

    Yes, you could, just like most other dot com boomers 😉
