Abstract

A video conferencing system for a vehicle includes a display device disposed in a passenger compartment of the vehicle, the display device comprising a screen, a first imager configured to capture a first image data corresponding to a field of view of a passenger compartment of the vehicle, at least one microphone configured to collect audio data from within the passenger compartment, and a controller. The controller is configured detect a display prompt within the image data corresponding to a portion of the image data received from the first imager, detect an audio prompt within a predetermined zone of the passenger compartment of the vehicle, and selectively crop the first image data according to the portion of the image data corresponding with the display prompt in response to determining a correlation between the portion of the image data and the zone of the passenger department associated with the audio prompt.

Core Innovation

The invention relates to an in-vehicle video conferencing system for a passenger compartment. The system includes a first imager configured to capture first image data corresponding to a field of view of the passenger compartment, and a plurality of microphones in respective predetermined locations corresponding with seating locations within the passenger compartment.

A controller receives information related to a vehicle motion state from a vehicle network and monitors for a display prompt within the image data and an audio prompt at least primarily from one of the plurality of microphones within one of the seating locations. The controller determines a correlation between the portion of the image data and the seating area associated with the audio prompt, including whether the seating area associated with the audio prompt is the driver seating location.

Responsive to vehicle motion state, the controller selectively crops the first image data according to the portion of the image data corresponding with the display prompt. Selective cropping based on the display prompt is performed differently depending on whether the audio prompt is associated with the driver seating location and whether the vehicle is in a motion state or not in a motion state, and the selectively cropped first image data is then used for video conferencing, including selectively transmitting cropped video and corresponding audio for conferencing.

The dependent refinements further define how the display prompt and audio prompt are detected and how the cropped content is prepared. For example, a display prompt can be determined based on detection of movement of one or more features of a vehicle occupant identified in the first image data, and the audio prompt can correspond to detecting a sound identifiable as speech.

Claims Coverage

The independent claim is clm-00001. It defines an in-vehicle video conferencing system with audio-vision prompting, correlation to seating locations, and motion-state-dependent selective cropping conditioned on whether the audio prompt is from the driver seating location. Dependent claims (clm-00002, clm-00003, clm-00004, clm-00006, clm-00008) refine prompt detection, cropping content, and conferencing integration/preprocessing.

In-vehicle passenger-compartment video and microphone sensing for conferencing

A video conferencing system for a vehicle with a first imager capturing first image data for a passenger-compartment field of view and a plurality of microphones in predetermined locations corresponding with seating locations to collect audio data, including a seating location corresponding with a driver seat location.

Motion-state-dependent control of display prompt region and audio prompt seat correlation

A controller receives vehicle motion state, monitors for a display prompt within the image data corresponding to a portion of the image data from the first imager, monitors for an audio prompt primarily from one of the microphones within one seating location, and determines a correlation between the portion of the image data and the seating area associated with the audio prompt.

Selective cropping conditioned on motion state and whether the audio prompt is from the driver seat

Responsive to the vehicle being in a motion state, the controller selectively crops the first image data according to the display-prompt portion only if the seating area associated with the audio prompt is not the driver seating location, and responsive to the vehicle not being in a motion state, the controller selectively crops the first image data according to the display prompt portion.

Conferencing integration with external server and passenger-compartment display

The controller transmits cropped image data and audio data to an external conference server and receives video and audio data back, and the received conference media is displayed.

Display prompt based on occupant feature movement

The display prompt is determined based on detection of movement of one or more features of a vehicle occupant identified in the first image data.

Audio prompt based on detecting speech-identifiable sound

The audio prompt corresponds to detecting a sound identifiable as speech.

Cropped image portion constrained to facial region

The image data contains a facial region of the occupant so that the portion of the image data associated with the display prompt includes the occupant facial region.

Digital scaling of selectively cropped image data

The controller digitally scales the selectively cropped first image data to an image size in an order related to the first image data before selectively cropping the first image data.

The claims cover a vehicle video conferencing system that uses first imager data and seat-associated microphone data to detect a display prompt and an audio prompt, correlates them to seating locations, and performs motion-state-dependent selective cropping. Dependent claims further specify prompt detection based on occupant feature movement and speech-identifiable sounds, constrain cropped content to facial regions, add digital scaling, and define conferencing integration with an external conference server and passenger-compartment display.

Stated Advantages

Motion-state-dependent selective cropping that accounts for whether the audio prompt is associated with the driver seating location.

Selective cropping tied to correlated display prompt image regions and audio-prompt seating locations.

Improved conferencing relevance by constraining the cropped image portion to a facial region and refining prompts based on occupant feature movement and speech-identifiable sounds.

Support for conferencing integration by transmitting cropped video/audio to an external conference server and receiving conference media back for display in the vehicle.

Documented Applications

In-vehicle video conferencing using passenger-compartment imaging and microphone sensing, including displaying conference video and audio back in the vehicle via passenger-compartment display configurations.
