3D Reconstruction Method of Space Target on Optical Images with Wide Baseline via Neural Radiance Field

Wide-baseline 3d Reconstruction from Digital Stills

The last decade saw tremendous progress in the area of structure-and-motion. Techniques have been developed to compute the camera trajectory and reconstruct scenes in 3D based on nothing but a video or a set of closely spaced images. No extra information or calibration is needed to perform the reconstruction. This paper presents extensions on the traditional shape-from-video pipeline in order t...

Dynamic 3D Scene Depth Reconstruction via Optical Flow Field Rectification

In this paper, we propose a depth propagation scheme based on optical flow field rectification towards more accurate depth reconstruction. In depth reconstruction, the occlusions and low-textural regions easily result in optical flow field errors, which lead ambiguous depth value or holes without depth in the obtained depth map. In this work, a scheme is proposed to improve the precision of dep...

Towards Rapid 3D Reconstruction on Mobile Phones from Wide Field-of-view Images

Rapid 3D reconstruction of environments has many applications for mobile augmented reality, ranging from creating models for visual tracking systems, interaction models for placing annotations and environment maps for realistic rendering of virtual objects. Ideally, a single user should be able to rapidly generate a coarse model of their surroundings using only a handheld device. To achieve thi...

Dense Matching Methods for 3D Scene Reconstruction from Wide Baseline Images

Wide-Baseline Multi-View Video Segmentation For 3D Reconstruction

Obtaining a foreground silhouette across multiple views is one of the fundamental steps in 3D reconstruction. In this paper we present a novel video segmentation approach, to obtain a foreground silhouette, for scenes captured by a wide-baseline camera rig given a sparse manual interaction in a single view. The algorithm is based on trimap propagation, a framework used in video matting. Bayesia...
