Abstract: In one embodiment, an apparatus includes a transmitter operable to transmit a first light beam from a light source. The apparatus also includes a receiver operable to receive a plurality of return light beams and direct the plurality of return light beams through a first beam splitter to an imaging sensor and a LiDAR sensor. The imaging sensor may be operable to process a first portion of the return light beams into image profile data, and the LiDAR sensor may be operable to process a second portion of the return light beams into depth profile data. In addition, the first and second portions of the return light beams may be received from a shared field of view.

The first filter pattern includes a number of first filter types. The method also includes accessing second image data generated by a second image sensor having a second filter array that has a second filter pattern different from the first filter pattern. The second filter pattern includes a number of second filter types, the number of second filter types and the number of first filter types have at least one filter type in common. The method also includes determining a correspondence between one or more first pixels of the first image data and one or more second pixels of the second image data based on a portion of the first image data associated with the filter type in common.

Abstract: In one embodiment, a method includes determining an operational status of a vehicle including a radar antenna. The operational status is related to autonomous-driving operations of the vehicle in an environment. The method includes determining an expected amount of signaling resources associated with the radar antenna to be utilized by the vehicle while the vehicle performs the autonomous-driving operations, based at least on the operational status of the vehicle and the environment. The method includes determining to switch one or more of the signaling resources associated with the radar antenna from a first mode to a second mode based on the expected amount of signaling resources to be utilized by the radar antenna while the vehicle performs the autonomous-driving operations. The method includes causing the one or more of the signaling resources associated with the radar antenna to switch from the first mode to the second mode.
