Multiple Camera Human Detection and Tracking inside a Robotic Cell - An Approach based on Image Warping, Computer Vision, K-d Trees and Particle Filtering

In an industrial scenario the capability to detect and track human workers entering a robotic cell represents a fundamental requirement to enable safe and efficient human-robot cooperation. This paper proposes a new approach to the problem of Human Detection and Tracking based on low-cost commercial RGB surveillance cameras, image warping techniques, computer vision algorithms, efficient data structures such as k-dimensional trees and particle filtering. Results of several validation experiments are presented.
