US11988775B1 Dynamic sensor illumination
Sensors, including time-of-flight sensors, may be used to detect objects in an environment. In an example, a vehicle may include a time-of-flight sensor that images objects around the vehicle, e.g., so the vehicle can navigate relative to the objects. Sensor data generated by the time-of-flight sensor can be impacted by glare. In some examples, an emitter system for illuminating a field of view can be dynamically altered to provide different illumination intensities at different regions in the field of view. For instance, locations at which a highly-reflective object or other object that is likely to cause glare may be illuminated at a lower illumination intensity, e.g., to reduce the likelihood of pixel saturation in measured data associated with the object.
