Abstract
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.
Claims18
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.
A processor comprising:
- one or more circuits to:
- identify a training dataset comprising a plurality of points, each of the plurality of points associated with a corresponding label identifying a prediction for an additional point and at least one corresponding weather condition parameter;
- and
- provide the training dataset to update a neural network, the neural network to generate predictions of whether additional points are to be added for corresponding emitters of input point clouds.
A method, comprising:
- identifying, using one or more processors, a point cloud comprising a plurality of points and at least one parameter of an atmospheric condition to simulate;
- modifying, using the one or more processors, an intensity of at least one of the plurality of points according to the at least one parameter of the atmospheric condition;
- updating, using the one or more processors and based at least on a subset of the plurality of points and the at least one parameter of the atmospheric condition, a number of points comprised in the point cloud;
- determining, using the one or more processors, at least one point of the plurality of points that satisfies an emitter threshold;
- and
- replacing, using the one or more processors, 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.
