View rendering for the provision of virtual eye contact using special geometric constraints in combination with eye-tracking

摘要

A virtual camera pose determiner is configured to determine a position and an orientation of a virtual camera. The position of the virtual camera is determined on the basis of a display position of a displayed representation of a remote participant on a display. The orientation of the virtual camera is determined on the basis of a geometrical relation between the display position of the remote participant on the display, and a position of a local participant. The virtual camera is configured to transmit an image or a sequence of images to the remote participant, so that an image provided by the virtual camera has the view on the local participant as is if viewed from the display position. Further embodiments provide a video communication system having a virtual camera pose determiner for providing a virtual camera pose on basis of the display position and the position of the local participant.

主权项

1. A virtual camera pose determiner, configured to determine a position and an orientation of a virtual camera,
wherein the position of the virtual camera is determined on the basis of a display position of a displayed representation of a remote participant on a display, wherein the orientation of the virtual camera is determined on the basis of a geometrical relation between the display position of the remote participant on the display, and a position of a local participant; wherein the virtual camera is configured to transmit an image or a sequence of images to the remote participant, so that an image provided by the virtual camera comprises the view on the local participant as is if viewed from the display position; wherein the display position is determined as one of a mid-eye position, a left eye position and a right eye position of the displayed representation of the remote participant; and wherein the position of the local participant is determined as one of a mid-eye position, a left eye position, and a right eye position of the local participant.
