Generating composite data using long and short time-of-flight exposures

Abstract

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 return unreliable pixels, e.g., in the case of over-exposure or saturation. In some examples, composite sensor data can be generated based on information from multiple exposures captured at different exposure times. In examples, pixels in a first exposure are matched to pixels in a second exposure to account for relative movement of the vehicle and the detected object in the composite sensor data.
