This paper presents an active tracking system that only uses depth image taken by Kinect. From the view point of Kinect, flexible software libraries including human detection and human-pose estimation cannot be applied when target people go outside of the viewing area, and the active tracking system solve or relax this problem. From the active-tracking -system viewpoint, different from other cameras, Kinect can take depth image in indoor scene independent of illumination conditions. This implies that the tracking system can keep tracking even in complete darkness. For single camera tracking system, Fixed Viewpoint Camera (FVC) setting, which does not change the 3D viewpoint under rotation, is useful for active tracking, because the rotation angle to keep target inside the image frame can directly computed from the 2D image position on the image plane. In the case of Kinect, however, we don’t have to use FVC settings if we know the relative viewpoint position from the rotation center, because 3D positional information is directly obtained from the sensor. First, we present the calibration method to know the relative position. Next, we present a 3D blob-tracking method based on mean-shift. Since this method uses 3D window function, the object separability from its background and the stability are both good when the target shape is roughly convex. As a tracking method using more precise 3D model, this paper also presents spin-image based tracking algorithm. Through the experiment, we discuss what method should be used for specific tasks. |
