“…However, the surface model method also has defects. 12,13 At present, the research of surface model is mainly divided into two aspects, ie, the representation, design, modeling, and display of curves and surfaces. Two is the research of algorithms related to surface design, such as intersection, equidistance, transition, splicing, smoothing, and local operation.…”

Summary Compared with traditional geometric modeling techniques, image‐based modeling technology has the advantages of simple operation, quick reconstruction, and strong sense of reality. Compared with the three‐dimensional scanning technology, it has the characteristics of low cost and simple algorithm. In a broad sense, the image‐based 3D modeling technique not only includes the geometric modeling of the entity but also includes visual restoration, ie, reconstruction of the geometric model of the entity using the image, and restoration of its corresponding surface texture, reflection properties, lighting conditions, and the like. This paper focuses on the application of geometric reconstruction methods to study the application of VR computer images in the three‐dimensional virtualization of sports human science. By combining the background difference method and the interframe difference method, the target region where the moving human body is located can be accurately extracted from the video, and then the idea of the human body can be divided along the virtual plane. Finally, the end‐point feature points of the human body are determined by the geodesic distance, and a three‐dimensional model skeleton is buried using a discrete penalty function, and an image‐based three‐dimensional reconstruction system is realized.

“…For instance, in a telepresence session which two MR users are communicating, a viewer may perceive another user's avatar and thus create a tangible sense of the presence of the other user in the viewer's environment [8]. One of the potential solutions is the reconstruction and detection of occluded portions of the 3D model of human body using depth data from a single viewpoint [9]. However, it may not have data for a certain part of an object due to occlusion.…”

Mixed Reality (MR) is a technology which enable to bring a virtual element into the real-world environment. MR intends to improve reality on the virtual world immerse onto real-world space. Occasionally the MR has been improved as the display technologies advanced progressively. In MR collaborative interface context, the local and remote user work together on collaborative task while sense the immersive environment in the cooperative application. User telepresence is an immersive telepresence, where the reconstruction of a human appears in a real-life. Up till now, producing full telepresence of the life-size human body may require a high transmission bandwidth of the internet. Therefore, this paper explores on a robust real-time 3D reconstruction method for MR telepresence. This paper discusses the previous works on the reconstruction method of a full-body human and the existing research works that have proposed the reconstruction methods for telepresence. Besides the 3D reconstruction method, this paper also enlightens our recent finding on the MR framework to transport a full-body human from a local location to a remote location. The MR telepresence will be discussed, as well as the robust 3D reconstruction method which has been implemented with user telepresence feature where the user experiences an accurate 3D representation of a remote person. The paper ends with the discussion and results, MR telepresence with robust 3D reconstruction method to execute user telepresence.

“…The surface reconstruction method designed for multiscale scenes uses very dense matching of feature points in multiple images to reconstruct the object surface [7]. The approach developed by Jang et al [8] uses multiple color images along with the depth image to extract the 3D surface and generate the 3D model. Although the method handles the self-occlusion problem, further improvement is needed to make the method robust.…”

Extracting 3D information from 2D images is an inverse estimation problem and a challenging task in itself. The aim of 2D to 3D reconstruction is to generate either a volume or a surface representing the object from multiple views. This paper presents a simple and accurate multiple-view volumetric 3D reconstruction method using an integrated approach based on homography estimation and voxel mapping. The homography-based approaches give accurate estimates but do not provide system dynamics. The voxel-based volumetric reconstruction methods provide system dynamics that are essential for system modeling. However, they face challenges while modeling the concavities. This paper presents a proposed 3D reconstruction method that combines homography estimation and the voxel mapping approach for improving the accuracy of 3D reconstruction. Experimental results show that the method efficiently reconstructs objects of known and unknown shape, fragile objects, and complex scenes with multiple objects. The use of homography along with voxel mapping in a multiple-camera environment brings out more details of the object for improving the quality of reconstruction.
