Object detection for before and after the instances when an older adult walks in the kitchen monitoring area and places a cooking bowl on the oven. Left column (a, c) is the detected objects from left (a) and right (c) sensors before an older adult walks into the scene. The right column (b, d) is the detected objects from the left (b) and right (d) sensors when the older adult leaves the scene. Notice the bowl was not detected in the view of the right sensor for when the older adult leaves the room. However, calibration results are used to segment the point cloud in view of the right sensor.
