DIY Rangefinder can tell distance using a Web Cam!

Here’s a great free application that will turn your web cam into a range finder that can tell distance simply by calculating the height of stuff. Now, this will work really well on the golf course as the flagstick in golf is always the same. (of course, there’s a different stand for USGA and the UK so…)

This site will show you how you can 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.
