MIT and Rice University researchers have developed a new computer vision technology called ORCa (Objects as Radiance-Field Cameras) that can turn any shiny object into a camera of sorts. This technology can be used to capture reflections from any metallic surface, such as coffee mugs, streetlight poles, and shiny cars. It works by using photos from multiple angles to map the surface of the object, and then an AI system turns the object into a virtual sensor to capture reflections. The output image is sharp enough to create a mirror image from a shiny surface, and this technology has potential applications in self-driving cars, crime-solving, and more.
