Coding hybrid multi-view sensor configurations

Abstract

A method for transmitting multi-view image frame data. The method comprises obtaining multi-view components representative of a scene generated from a plurality of sensors, wherein each multi-view component corresponds to a sensor and wherein at least one of the multi-view components includes a depth component and at least one of the multi-view components does not include a depth component. A virtual sensor pose is obtained for each sensor in a virtual scene, wherein the virtual scene is a virtual representation of the scene and wherein the virtual sensor pose is a virtual representation of the pose of the sensor in the scene when generating the corresponding multi-view component. Sensor parameter metadata is generated for the multi-view components, wherein the sensor parameter metadata contains extrinsic parameters for the multi-view components and the extrinsic parameters contain at least the virtual sensor pose of a sensor for each of the corresponding multi-view components. The extrinsic parameters enable the generation of additional depth components by warping the depth components based on their corresponding virtual sensor pose and a target position in the virtual scene. The multi-view components and the sensor parameter metadata is thus transmitted.
