TIME OF FLIGHT CAMERAS USING PASSIVE IMAGE SENSORS AND EXISTING LIGHT SOURCES

A vehicle may perform time of flight (ToF) calculations or determinations using passive sensors (e.g., passive image sensors) with existing onboard vehicle light sources to generate depth data and a depth image of a scene surrounding the vehicle. For example, the vehicle may use an automotive camera...

Zusammenfassung:	A vehicle may perform time of flight (ToF) calculations or determinations using passive sensors (e.g., passive image sensors) with existing onboard vehicle light sources to generate depth data and a depth image of a scene surrounding the vehicle. For example, the vehicle may use an automotive camera (e.g., a passive sensor that does not emit light) and may pair the camera with one or more light sources on the vehicle to construct a ToF camera. To accomplish this construction of a ToF camera using existing automotive cameras and existing light sources, a controller of the vehicle synchronizes the passive automotive cameras to the onboard light sources. In some examples, the vehicle can enable a high dynamic range (HDR) for the ToF cameras by varying properties of the light emitted from the light sources.
