UC Santa Barbara Develop 3D X-Ray Imaging

Using off-the-shelf drones, WiFi transceivers, and Tango-enabled tablets, researchers at UC Santa Barbara have developed a way to perform 3D imaging of objects hidden by walls.

The technique is conceptually simple: Two drones work together, flying around a brick house with a hidden interior. One drone broadcasts a WiFi signal, and the other drone captures the signal from the other side of the house. The solution builds on earlier work in sensing and imaging using WiFi. Back in 2010, the lab demonstrated 2D imaging using WiFi signals and terrestrial robots.

“However, enabling 3D through-wall imaging of real areas is considerably more challenging due to the considerable increase in the number of unknowns,” said Yasamin Mostafi, Professor at UC Santa Barbara. Unsurprisingly, the secret sauce that makes the experiment successful is the flexibility of the drones.

研究人员预先定义了无人机的路径，以在保持操作效率的同时在所有三维中捕获尽可能多的变化。“
