I have a school project and I need to do perimeter control in an open area.
So I have a drone up in the air to provide live video feed into my computer but I have no idea how to detect when something enters the area/perimeter.
Is there any software to do this?
If you have a static positioned webcam, you can use Linux as an os with the program "motion" - it detects changes in the webcam view, and then can run a script when motion is detected. Lots of other options like sensitivity level, watching only a certain area of the image for change, how long change must be taking place from reference frame for it to be considered "motion", how long to reset after an alert, etc. Both Free and free...

What about motion?

Description: V4L capture program supporting motion detection
Motion is a program that monitors the video signal from
one or more cameras and is able to detect if a significant
part of the picture has changed. Or in other words, it can
detect motion.
.
Motion is a command line based tool. It has no graphical
user interface. Everything is setup either via the
command line or via configuration files.
.
The output from motion can be:
- jpg/ppm image files
- mpeg/mp4/swf/flv/mov/ogg video sequences
.
Also, motion has its own minimalistic web server. Thus,
you can access the webcam output from motion via a browser.
