Scalable multi-view stereo camera array for real world real-time image capture and three-dimensional displays
… is escalating and yet the capturing devices for multiple view content are focused on either single camera precision rigs that are limited to stationary objects or the use of synthetically created animations. In this work we will use the existence of inexpensive digital CMOS cameras to explore a …

High-Fidelity Image -Based Modeling
… scene reconstruction, we propose two novel multi-view stereo algorithms. In the first algorithm, after building a visual hull model purely from geometric constraints associated with image silhouettes, we identify rims where the surface grazes the visual hull model, which is then carved by …

DeepMVS: learning multi-view stereopsis
… deep convolutional neural network (ConvNet) for multi-view stereo reconstruction. Taking an arbitrary number of posed images as input, we first produce a set of plane-sweep volumes and use the proposed DeepMVS network to predict high-quality disparity maps. The key contributions that enable these …

Automated image-based 3D reconstruction system for precise plant modeling
… components such as Structure from Motion(SFM), Multi-View Stereo(MVS) or 3D Object Segmentation, are explicitly analyzed with preliminary experiments that were performed individually on the plant objects. The results show that simple combination of existing work does not generate satisfying …

The Digital Dead: Virtual Modelling of Human Remains using Photogrammetry for Presentation and Preservation by Record.
… from overlapping images, Structure-from-Motion Multi-view Stereo photogrammetry, offers a fast, accessible analysis method which reduces risk of damaging the remains. The current study set out to investigate whether photogrammetry can create close-range models of osteological material that are …

Improve OpenMVG and create a novel algorithm for novel view synthesis from point clouds
… to render photorealistic images from new views given a photo collection and 3D point cloud. First, the original OpenMVG is parallelized using GPU and its data structure is optimized. Moreover, we integrated the MatchMiner algorithm into OpenMVG to further improve its efficiency. Last but …

Learning Monocular Cues in 3D Reconstruction
… of the learned monocular cues. The first is multi-view depth estimation, where we use single-view depth probability distribution to improve the efficiency of depth candidate sampling and enforce the multi-view depth to be consistent with the single-view predictions. We also propose an …

D4AR-4 dimensional augmented reality-models for automation and interactive visualization of construction progress monitoring
… as-built point cloud models are enhanced with a multi-view stereo algorithm and are fed into a novel voxel coloring and labeling algorithm to increase density of the as-built point cloud models, and traverse and label the integrated as-built and as-planned models for expected visibility and …
