NEC image-processing tech can detect invisible damage to bridges

NEC has developed a camera system that can detect deterioration in bridges and other structures simply by analyzing imagery.The electronics manufacturer is calling it the world’s first system to use high-definition video cameras and image-recognition technologies to analyze and estimate structural vibrations.NEC researchers developed an algorithm that can pick up numerous minute vibrations on the surface of a structure by analyzing imagery of it, the company said Tuesday.
