Researchers at University of Tsukuba have developed a noncontact vibration measurement method using an event camera, a sensing technology inspired by biological vision. By applying geometric analysis ...

An event camera–based system, “Event topology-based visual vibrometer,” that measures vibrations of objects without physical contact. The image illustrates the measurement of a guitar string. By ...

Speed cameras use multiple kinds of technology to get driver's speeds. But they're not perfect, and there are several issues ...
