    Abstract: A method of producing vertically projecting three-dimensional images using virtual 3D models (22), wherein said 3D models (22) are created by the simultaneous localization and depth-mapping of the physical features of real objects. A camera (17) is used to take a first image (22A) from a first perspective, and a subsequent image (22N) from a subsequent perspective, wherein the autofocus system (18) provides a first set of depth mapping data and a subsequent set of depth mapping data. The first set of depth mapping data and the subsequent set of depth mapping data are used to generate a disparity mapping (21). A virtual 3D model (32) is created from the disparity mapping (21). The virtual 3D model (32) is imaged to obtain images that can be viewed as three-dimensional. Enhanced 3D effects are added to the virtual 3D model (32).

    Abstract: A system for determining a person's field of view with respect to captured data (e.g., recorded audiovisual data). A multi-camera capture system (e.g. bodycam, vehicular camera, stereoscopic, 360-degree captures system) records audiovisual data of an event. The field of capture of a capture system or a field of capture of captured data combined from multiple capture systems may be greater than the field of view of a person. Facial features (e.g. eyes, ears, nose, and jawlines) of the person may be detected from the captured data. Facial features may be used to determine the field of view of the person with respect to the captured data. Sensors that detect head orientation may be used to determine the field of view of the person with respect to captured data. The field of view of the person may be shown with respect to the captured data when the captured data is played back.

    Abstract: The invention is directed to recording, transmitting, and displaying a three-dimensional image of a face of a user in a video stream. Reflected light from a curved or geometrically shaped screen is employed to provide multiple perspective views of the user's face that are transformed into the image, which is communicated to remotely located other users. A head mounted projection display system is employed to capture the reflective light. The system includes a frame, that when worn by a user, wraps around and grips the user's head. Also, at least two separate image capture modules are included on the frame and generally positioned relatively adjacent to the left and right eyes of a user when the system is worn. Each module includes one or more sensor components, such as cameras, that are arranged to detect at least reflected non-visible light from a screen positioned in front of the user.

    Abstract: A first image capture component may capture a first image of a scene, and a second image capture component may capture a second image of the scene. There may be a particular baseline distance between the first image capture component and the second image capture component, and at least one of the first image capture component or the second image capture component may have a focal length. A disparity may be determined between a portion of the scene as represented in the first image and the portion of the scene as represented in the second image. Possibly based on the disparity, the particular baseline distance, and the focal length, a focus distance may be determined. The first image capture component and the second image capture component may be set to focus to the focus distance.
