1. A method comprising:
- receiving, at a processor of a sensor fusion system of a vehicle, an environmental model comprising raw measurement data from a plurality of sensors of the vehicle, the plurality of sensors having distinct modalities, wherein the raw measurement data is temporally aligned in the environmental model and spatially aligned in the environmental model based on where the sensors are mounted in the vehicle;
receiving, at the processor, object annotations indicating a detection of at least one object based on the raw measurement data in the environmental model, the object annotations comprising a confidence level associated with the detection of the at least one object;
modifying, via the processor, the environmental model to include the object annotations, resulting in an annotated environmental model, wherein the object annotations are temporally aligned and spatially aligned in the annotated environmental model;
generating, via the processor, a classification result of a current situation of the vehicle based, at least in part, on the raw measurement data and the object annotations in the annotated environmental model; and
transmitting, via the processor, the classification result to a processor associated with driving functionality of the vehicle, wherein the processor associated with driving functionality is configured to control operation the vehicle based, at least in part, on the classification result.

Abstract
Systems, methods, and computer-readable storage mediums which use annotated environmental models for sensor modification are disclosed. A computing system receives an environmental model for a vehicle. The environmental model can include data from a plurality of modalities. Object annotations are received from sensors which are used to modify the environmental model, creating an annotated environmental model. A classification of a current situation is generated using the annotated environmental model, and a sensor is modified using the classification.
