Human position estimation in Intelligent Space for an active information display

In this paper, we introduce a new active information display system which is based on Intelligent Space and a projector mounted mobile robot. This system is able to afford a human with relevant information by projecting it on where the human is looking such as a wall, a floor, and a door. For this system, Intelligent Space should recognize location of human. To estimate position of human in Intelligent Space using multiple camera system, we propose a human detection method based on the Histogram of Oriented Gradients(HOG) feature descriptors and the boosting technique in each camera and a position estimation method using multiple view geometry. The performance of proposed method for human position is verified by real-time experiments.
