An important application of aerial video surveillance pertains to assistance in emergency rescue operations, where regions struck by natural calamities such as earthquakes, floods, and tsunami can be monitored to detect activity of living beings. A low cost, easily deployable framework of multiple surveillance cameras is desired to perform such aerial surveillance. Many approaches exist for performing aerial video surveillance; one such approach is using helium balloons. In our system we use helium balloons to make the camera air borne, which reduces the system’s cost and deployment efforts. Suspending a camera from helium balloon causes jitters, which makes the task of motion detection challenging. Creating a background model to detect ground activity from a moving camera requires camera motion to be computed and compensated. Bandwidth congestion is another important issue to be considered in an aerial video surveillance system. We present a study of our low cost, scalable, and easily deployable framework of multiple aerial surveillance cameras to detect ground activity in emergency situations.
