In this work, I proposed a practical system for detecting 3D volumetric intrusion in a predefined restricted area using depth images provided by a range camera.
This system can be employed for the protection of valuable objects displayed in public areas, as well as for monitoring the space around private property assets. The system defines a virtual 3D shield around the asset that has to be protected, thus delimiting the protected boundaries in all 3 dimensions.
Experimental results performed with both passive stereo camera and active infrared (IR) stereo confirmed that the proposed method effectively localized the intrusion in the volume of the monitored object.
Intrusion Detection (Factory Setting)
Factory-like activity in which the safety zone had to be monitored from a bird’s eye perspective in order to guarantee both ergonomic processes and efficient results.
In order to have everything in sight, the camera system was mounted at a height of 7m above the ground floor.
To generate a good quality depth map we employed a passive stereo camera that exhibited a canonical setup (two monochrome cameras) with a baseline of 100cm.
