We propose a new end-to-end architecture that directly extracts a bird's-eye-view representation of a scene given image data from an arbitrary number of cameras. The core idea behind our approach is to \"lift\" each image individually into a frustum of features for each camera, then \"splat\" all frustums into a rasterized bird's-eye-view grid.
