Shown below is a video of a robot that uses the perceived vanishing point of an image to navigate through a corridor. The robot, based on an iRobot Create, uses a standard webcam and video processing to locate the vanishing point of what it sees, and navigates towards that point. Such navigation wor
Bob,
Thanks for the input. You don’t happen to have any pictures or video of your robot, do you? I’d love to see some.
I can definitely see the limitations of this implementation, but coupled with other means of navigation, it might be useful. I can also see how it can be used in specific situations - perhaps hospitals?
I tried doing this a couple of years ago, and it does work but only in corridor type situations. Notice in this case that the black stripe at door handle height is providing a strong cue.
It turns out that there are plenty of situations in a home or office environment where vanishing points cannot be easily computed.
