Nvidia patents method to build 3D maps from video frames
Nvidia describes a technique for creating depth maps, which show how far away objects are in a scene, by analyzing video frames. The process combines data from the current frame and the previous one to calculate a more accurate 3D representation of the environment.
In the filing’s own words
The disclosed method for generating a first depth map for a first frame of a video includes performing one or more operations to generate a first intermediate depth map based on the first frame and a second frame preceding the first frame within the video, performing one or more operations to generate a second intermediate depth map based on the first frame, and performing one or more operations to combine the first intermediate depth map and the second intermediate depth map to generate the first depth map.
What exactly they claim (claim 1)
1. A computer-implemented method for generating a three-dimensional (3D) Gaussian mixture model (GMM) representing a scene, the method comprising: performing one or more expectation operations to determine affinities between one or more portions of the 3D GMM and one or more points of a point cloud representing one or more features in the scene; and performing one or more maximization operations to update shapes and locations of the one or more portions of the 3D GMM that correspond to the one or more features based at least on the affinities.
