| description | METHOD AND A DEVICE FOR RECONSTRUCTINGA POINT CLOUD REPRESENTATIVE OF A SCENE USING LIGHT-FIELD DATA The present invention relates to the reconstruction of point cloud representing a scene. Point cloud data take up large amounts of storage space which makes storage cumbersome and processing less efficient. To this end, it is proposed a method for encoding a signal representative of a scene comprising parameters representing the rays of light sensed by the different pixels of the sensor are mapped on the sensor. A second set of encoded parameters are used to reconstruct the light-field content from the parameters representing the rays of light sensed by the different pixels of the sensor, a third set of parameters representing the depth an intersection of said ray of light represented by said first set of parameters with at least an object of said scene and a fourth set of parameters representing color data are used to reconstruct the point cloud on the receiver side. |
