MULTILIGHTTRACKER: VISION BASED MULTI OBJECT TRACKING ON SEMI-TRANSPARENT SURFACES

Jesper Nielsen, Kaj Grønbæk

Abstract

This paper describes MultiLightTracker (MLT) - a simple and robust system for simultaneous tracking of multiple objects on 2D semi-transparent surfaces. We describe how the system performs object tracking on a surface which can be simultaneously used for back projection, allowing direct and undisturbing single- or multi-user interaction with the projected content. The system is vision based, supporting both 4:3 and 16:9 picture formats, and it requires only a webcam and a recent PC to work. MultiLightTracker currently tracks four different objects simultaneously in real time (~100ms latency) but the aim is to extend this number. In controlled environments such as meeting rooms or living rooms, MultiLightTracker is sufficiently robust for everyday collaborative use. Thus, MultiLightTracker is superior to existing multi-object tracking surfaces with regards to its easy availability, simplicity and comparable low cost.
