When the first instant photo was taken 75 years ago with a Polaroid camera, it was groundbreaking to rapidly capture the 3D world in a realistic 2D image. Today, AI researchers are working on the opposite: turning a collection of still images into a digital 3D scene in a matter of seconds.
Nvidia applied this approach to a popular new technology called neural radiance fields . The result, dubbed Instant NeRF, is the fastest NeRF technique to date, achieving more than 1 000-times speedups in some cases. The model requires just seconds to train on a few dozen still photos — plus data on the camera angles they were taken from — and can then render the resulting 3D scene within tens of milliseconds.
In a tribute to the early days of Polaroid images, NVidia Research recreated an iconic photo of Andy Warhol taking an instant photo, turning it into a 3D scene using Instant NeRF.NeRFs use neural networks to represent and render realistic 3D scenes based on an input collection of 2D images. From there, a NeRF essentially fills in the blanks, training a small neural network to reconstruct the scene by predicting the color of light radiating in any direction, from any point in 3D space. The technique can even work around occlusions — when objects seen in some images are blocked by obstructions such as pillars in other images.While estimating the depth and appearance of an object based on a partial view is a natural skill for humans, it’s a demanding task for AI.
