Outline of Final Research Achievements

We developed a system which tracks multiple flying objects in 3D spalce in real-time and projects particular information onto each object. Six motion capture cameras (250fps) were used to track objects with less occlusion problem. When speed of the object is fast, the projection is delayed. We introduced a prediction model with Kalman filter and succeeded to minimize this issue.
