Abstract
A method for generating a moving volumetric image of a moving object from data recorded by a user-held device comprising: acquiring, from the user-held device, video and depth data of the moving object, and pose data; and communicating the acquired data to a computing module. Then, processing the video data to extract images that are segmented to form segmented images; passing the segmented images, depth data and pose data through a processing module to form a sequence of volumetric meshes defining the outer surface of the moving object; rendering the sequence of volumetric meshes with a visual effect at least partly determined from the video data to form a rendered moving volumetric image; and communicating the rendered moving volumetric image to at least one device including the user-held device. Then, displaying, at a display of the at least one device, the rendered moving volumetric image.

Abstract

The method comprising providing a plurality of images of a scene captured by a plurality of image capturing devices (101); providing silhouette information of at least one object in the scene (102); generating a point cloud for the scene in 3D space using the plurality of images (103); extracting an object point cloud from the generated point cloud, the object point cloud being a point cloud associated with the at least one object in the scene (104); estimating a 3D shape volume of the at least one object from the silhouette information (105); and combining the object point cloud and the shape volume of the at least one object to generate a three- dimensional model (106). An apparatus for generating a 3D model, and a computer readable medium for generating the 3D model.
