Nvidia patents method to simulate weather effects on sensor data
Nvidia has been granted a patent for a system that adjusts digital 3D maps, known as point clouds, to mimic specific weather conditions. The technology changes the brightness of individual points and adds new ones to simulate how rain, fog, or other atmospheric effects would alter what a sensor sees.
In the filing’s own words
In various examples, systems and methods are disclosed relating to transforming sensor measurements according to configurable atmospheric conditions. One or more circuits can identify a point cloud comprising a plurality of points and a parameter of a weather condition to simulate and modify an intensity of at least one of the plurality of points according to the parameter of the weather condition. The one or more circuits can update, based at least on a subset of the plurality of points and the parameter of the weather condition, the point cloud to include one or more additional points.
What exactly they claim (claim 1)
1. A processor comprising: one or more circuits to: identify a point cloud comprising a plurality of points and at least one parameter of a weather condition to simulate; modify an intensity of at least one of the plurality of points according to the at least one parameter of the weather condition; update, based at least on a subset of the plurality of points and the at least one parameter of the weather condition, a number of points comprised in the point cloud; determine at least one point of the plurality of points that satisfies an emitter threshold; and replace the at least one point of the plurality of points with at least one additional point having a higher intensity than the at least one point.
