The resulting visual information can be used to estimate the number of storm refugees and assess the need for health and humanitarian services. \u003C\/p\u003E\n\u003Cp\u003EAid organizations currently don\u0027t have a quick and accurate way to determine how many people need assistance. Satellites can collect images of areas affected by a natural disaster, but there are dissemination restrictions and cloud cover can prevent collection of images.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022Without a real-time map, it\u0027s very hard to do population estimates and demographic estimates to figure out where people are, how they\u0027re moving, how they\u0027re spaced out and even how many people you have on the ground,\u0022 said Benjamin Sklaver, a project officer from the Centers for Disease Control and Prevention (CDC) International Emergency and Refugee Health Branch. \u0022This technology does not exist currently, so GTRI\u0027s imaging system is really an innovative project.\u0022 \n\u003C\/p\u003E\n\u003Cp\u003EThe imaging system was developed with funding from the CDC, and agency officials would like to begin using this device as soon as possible. After responding to the recent devastation caused by Hurricanes Hanna and Ike, the CDC asked GTRI to accelerate delivery of the imaging device for use during the 2008 hurricane season.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022We plan to package the system for use on Coast Guard UH-60J Black Hawk helicopters, which were among the first to fly over Haiti following Hanna\u0027s devastation,\u0022 said David Price, a GTRI senior research technologist.\n\u003C\/p\u003E\n\u003Cp\u003EThe imaging system - designed by Price and senior research engineer Gary Gray - is called the \u0027Mini ModPOD,\u0027 which stands for \u0027Miniature Modular Photographic Observation Device.\u0027 It consists of an off-the-shelf Canon Digital Rebel XTi digital camera, a global positioning system receiver, a small circuit board that uploads mission parameters, and an inertial measurement unit that measures the aircraft\u0027s rate of acceleration and changes in rotational attributes, including pitch, roll and yaw. The images collected from the system can be stitched together to create a complete picture of the affected area.\u003C\/p\u003E\n\u003Cp\u003EThe research team has tested the device on several flights, selecting areas with large populations of people likely to be outdoors.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022During the first test flight, we wanted to test the clarity and resolution of the images collected during the run, and we were very pleased,\u0022 said Price. \u0022We could see tennis balls on the ground and people reading books at outdoor tables. This was sufficient detail to allow accurate counting the number of people in an area.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EAfter the first flight, the researchers reduced the weight of the device and developed a more accurate geo-referencing capability, which allowed the physical location of the scenes shown in each photograph to be determined with precision. With the modifications made, the researchers went for a second flight test in July. \n\u003C\/p\u003E\n\u003Cp\u003EThe research group selected a rectangular zone of interest and loaded the latitude and longitude coordinates of the zone into the system from a USB drive. As soon as the helicopter flew into the zone, the camera began snapping pictures. The electronics were set to measure the speed of the aircraft so that each photo overlapped 60 percent of the preceding photo, making it easier to stitch together the photos to create a complete picture. The pilot made two passes, at altitudes of 500 and 1,000 feet above ground level.\u003C\/p\u003E\n\u003Cp\u003E\u0022This test flight was successful in confirming the Mini ModPOD\u0027s ability to activate the camera within the zone of interest. The resulting photos were extremely sharp and clear - they were free of any vibration or motion effects,\u0022 added Price.\n\u003C\/p\u003E\n\u003Cp\u003EThe photos were successfully matched to the flight data, which enabled the CDC to adjust them for geospatial reference. However, due to a software glitch, they were not overlapped as planned. The researchers made a small adjustment to the software and completed a third a third test flight in August.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022This flight resulted in images that were 60 percent overlapped, enabling CDC engineers to build a high-resolution mosaic image,\u0022 noted Price. \u0022Individuals on the ground were easily distinguishable as people separate from other objects.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EThe imaging system will also be available to the CDC and other agencies, such as the American Red Cross, to count people in refugee camps in order to plan for health and humanitarian services.\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cem\u003EThe research described in this article was supported by cooperative agreement #U38 EH000363 from the CDC.
