Drone Virtual Fence Using a Neuromorphic Camera

International Conference on Neuromorphic Systems 2021, 2021
Neuromorphic cameras are well suited to detect the motion of propellers (blades) on Unmanned Aerial Systems (UAS), or drones. In this paper, we introduce the concept of a virtual fence which is a low-cost networked situational awareness device to quickly alert that a drone has entered the zone.

Research platform for cattle virtual fences

2020 IEEE International Conference on Industrial Technology (ICIT), 2020
Prior work in virtual fences has proposed different schemes to keep cattle confined within a remotely configured perimeter. These techniques share a common pattern that consists in placing an electronic device in the animal capable of applying a stimulation when it approaches the pre-established limits.

Virtual Fence for a Surveillance System

2009
This paper presents a method for defining one or more virtual restricted zones within a surveillance area which is observed with stereo cameras. When an object enters a restricted zone, the system highlights the object shown in the monitoring screen or triggers other devices to produce a visual or auditory alarm. The proposed method works by extracting

Dynamic Virtual Fences for Controlling Cows

2006
A virtual fence is created by applying an aversive stimulus to an animal when it approaches a predefined boundary. It is implemented by a small animal-borne computer system with a GPS receiver. This approach allows the implementation of virtual paddocks inside a normal physically-fenced paddock.

A virtual fence for animals management in rangelands

MELECON 2008 - The 14th IEEE Mediterranean Electrotechnical Conference, 2008
Protecting biotopes and maintaining biodiversity are ecological aims highlighted in European policies. Grazing systems which have to adapt to these new constraints require new fencing technologies. Here we present a virtual fence based on an electromagnetic coupling principle.

From Robots to Animals: Virtual Fences for Controlling Cattle

The International Journal of Robotics Research, 2006
We consider the problem of monitoring and controlling the position of herd animals, and view animals as networked agents with natural mobility but not strictly controllable. By exploiting knowledge of individual and herd behavior we would like to apply a vast body of theory in robotics and motion planning to achieving the constrained motion of a herd.

Virtual fencing – past, present and future1

The Rangeland Journal, 2007
Virtual fencing is a method of controlling animals without ground-based fencing. Control occurs by altering an animal’s behaviour through one or more sensory cues administered to the animal after it has attempted to penetrate an electronically-generated boundary.
