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

Figure 3

Initialization steps for setting-up the monitoring environment for our study: (a) a typical monitoring area showing the placement of two RGB-D sensors and the calibration prop/object; (b) the resolved world coordinate associated with the monitoring area (red, green, and blue coordinate axes). This coordinate system is then used to merge point clouds obtained from all sensors. (c) Complementary calibration follow-up procedure for associating the physical dimensions of the monitoring scene to the sensed information.
