people detection sensor

Crowd Detection Alert System

It aims to detect the number of people entering or exiting a mall (or any public place) and if the value exceeds the threshold max number of people in an area, then the respective staff or officials are alerted that more number of people have accumulated and it is dangerous. This helps the authorities in taking right decisions at that time ...

People Detection and Tracking with TOF Sensor | IEEE ...

20080903· People Detection and Tracking with TOF Sensor Abstract: This paper presents a method to detect, track and count people which pass a confined space using the latest 3D TimeofFlight (ToF) sensor technology. A slicing algorithm is employed and a novel method is proposed which derives the slicing level based on the probability density function and histogram respectively. It was found that the ...

Electric Field Proximity Sensor

The People Detector (also known as the "Electric Field Proximity Sensor") is an microelectronic based device that can detect the presence of both moving and stationary objects through solid materials. Its ability to operate through any nonconductive material permits complete invisibility. The sensor functions by detecting small changes in an ultralowpower electromagnetic field generated ...

People Detection and Tracking Using LIDAR Sensors

the detection and tracking of people are included between the most important ones, since many tasks that the robots must perform depend completely on the correct detection and later tracking of a specific person. This work proposes a solution for tracking people during their interaction with the robot in domestic environments using a single LIDAR sensor. During competitions, these sensors are ...
