Lidar, the laser-bouncing tech used in self-driving cars, is pretty versatile. When it's not making autonomous vehicles smarter, it can be used for uncovering lost cities, finding bodies in unmarked graves, helping protect areas from wildfires, and … judging athletic contests? That's the application that Fujitsu has in mind with a new lidar-based system it thinks could help human judges assess gymnastics judging -- or potentially even replace the need for flesh-and-blood judges altogether. The idea behind the project is that gymnastics judges have to evaluate routines involving highly precise maneuvers. Due to human errors of judgment, however, scoring can vary, leading to accusations of bias or favoritism.
