    摘要： An object is to obtain three-dimensional shape data with high accuracy from three-dimensional shape data representing an approximate shape of an object. Three-dimensional shape data of an object captured in a plurality of captured images whose viewpoints are different is obtained (302). Further, surface three-dimensional information on the object is derived (303) based on the plurality of captured images. Then, the derived surface three-dimensional information is selected (304) based on a distance from the shape surface of the object represented by the three-dimensional shape data.

    摘要： 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.

    摘要： The invention notably relates to a computer-implemented method for 3D reconstruction. The method comprises providing 2D images and, for each 2D image, camera parameters which define a perspective projection. The 2D images all represent a same real object. The real object is fixed. The method also comprises providing, for each 2D image, a smooth map. The smooth map has pixel values, and each pixel value represents a measurement of contour presence. The method also comprises determining a 3D modeled object that represents the real object. The determining iteratively optimizes an energy. The energy rewards, for each smooth map, projections of silhouette vertices of the 3D modeled object having pixel values representing a high measurement of contour presence. This forms an improved solution for 3D reconstruction.

    摘要： A device, system, and method cast a ray projection from a perspective view. The method includes determining a first mask for a first object from a first frame captured by a first camera. The method includes determining a second mask for the first object from a second frame captured by a second camera. The method includes generating a 3D mask by associating the first mask and the second mask. The method includes determining a location of the 3D mask. The method includes generating the ray projection of the 3D mask from a perspective of a second object.

    摘要： An object is to obtain three-dimensional shape data with high accuracy from three-dimensional shape data representing an approximate shape of an object. Three-dimensional shape data of an object existing in an image capturing space is obtained (302). Further, a plurality of distance images each representing a distance to the object and corresponding to a plurality of viewpoints is obtained (305). Then, correction to evaluate the three-dimensional shape data based on the plurality of distance images and based on results of the evaluation, delete a unit element estimated not to represent a shape of the object among unit elements configuring the three-dimensional shape data is performed (307).
