Researchers in Australia used an Xbox Kinect sensor as an input camera to help drones ‘see’ their environment. They developed algorithms to process the video footage image by image, to help the drones know their own speed, motion, and to detect obstacles so they can reach their target position. The algorithm uses the images the drone ‘sees’ and compares the same pixel to detect the differences in 2-D images and calculates the speed and location of drones in 3-D space. As the RGB-D cameras are still in their infancy, they suffer from performance drawbacks such as limited operational range and relatively low resolution. According to the researchers, in future, it may be possible to use the drones to help rescue people from earthquakes, help mining industries with underground detection…read more.
