Passive Observer of Activities for Aging in Place Using a Network of RGB-D Sensors

Figure 8

Two views of the calibrated virtual scene based on the merged point clouds of the two depth sensors. Both views show the segmented portion of the point clouds associated with the detected objects after the older adult has left the monitoring area. Virtual reconstruction size of the point cloud is based on the physical sizes of the objects. The detected objects in the RGB image are used to segment the associated point cloud for determining their approximate position with respect to the real and virtual scene. For example, the orange path represents point clouds associated with the final position of the remote. Although it is not used as a part of the results of this paper, pink path shows an example trajectory of person while active in the room.
