Abstract: A method and system for synthetic data generation and analysis includes generating a synthetic dataset. A set of parameters is determined and scenarios are generated from the parameters that represent three-dimensional scenes. Synthetic images are rendered for the scenarios. A synthetic dataset may be formed to have a controlled variation in attributes of synthetic images over a synthetic dataset. The synthetic dataset may be used for training or evaluating a machine learning model.

Abstract: A concurrent simulation of multiple sensor modalities includes identifying the multiple sensor modalities in association with a simulation scenario, determining a timeline interleaving a publishing or operating frequency of each of the multiple sensor modalities relative to each other, determining a current time interval of a sliding window in the timeline, determining a simulation segment of the simulation scenario using the current time interval of the sliding window, rendering a scene based on the simulation segment, executing a simulation to concurrently simulate the multiple sensor modalities using ray tracing in the rendered scene, and generating simulated sensor data of the multiple sensor modalities based on executing the simulation.

Abstract: Simulating data received by a detection and ranging sensor including determining a first set of sample points on a surface of a simulated detector, the first set of sample points including a first sample point at a first location on the detector and a second sample point at a second location on the detector; generating a first ray associated with the first sample point, the first ray representing electromagnetic radiation reflected at a first point of intersection within a scene and incident on the first sample point on the surface of the detector; generating a second ray associated with the second sample point; the second ray representing electromagnetic radiation reflected at a second point of intersection within the scene and incident on the second sample point on the surface of the detector; and generating a ray-based data representation based on the first ray and the second ray.
