A sensor simulation system may generate sensor data for simulation by rendering a two-dimensional view of a three-dimensional simulation environment. In various examples, a sensor simulation system uses sensor dependency data to determine particular views to be re-rendered at different times during the simulation. The sensor simulation system may also generate a unified view with multiple sensor data at each region (e.g., pixel) of the two-dimensional view for use by different sensor types. In some implementations, a mixing technique may be used in which a view is generated using rasterization, followed by using ray tracing to align the view with a particular sensor. Spatial and temporal up-sampling techniques may also be used, including depth-aware and velocity-aware analysis of simulated objects to improve view resolution and reduce the frequency of rerendering the view.

    一种传感器模拟系统可以通过渲染三维模拟环境的二维视图来生成用于模拟的传感器数据。在各种示例中,传感器模拟系统使用传感器依赖性数据来确定要在模拟期间的不同时间处重新渲染的特定视图。传感器模拟系统还可以在二维视图的每个区域(例如,像素)处生成具有多传感器数据的统一视图,以供不同传感器类型的使用。在一些实现中,可以使用混合技术,其中使用光栅化来生成视图,之后使用射线追踪来将视图与特定传感器对准。还可以使用空间和时间的上采样技术,其包括对模拟对象的深度感知和速度感知分析,以提高视图分辨率并降低重新渲染视图的频率。
