چکیده

We present a novel variational approach to estimate dense depth maps from multiple images in real-time. By using robust penalizers for both data term and regularizer, our method preserves discontinuities in the depth map. We demonstrate that the integration of multiple images substantially increases the robustness of estimated depth maps to noise in the input images. The integration of our method into recently published algorithms for camera tracking allows dense geometry reconstruction in real-time using a single handheld camera. We demonstrate the performance of our algorithm with real-world data.

ElasticFusion: Real-time dense SLAM and light source estimation

We present a novel approach to real-time dense visual SLAM. Our system is capable of capturing comprehensive dense globally consistent surfel-based maps of room scale environments and beyond explored using an RGB-D camera in an incremental online fashion, without pose graph optimisation or any post-processing steps. This is accomplished by using dense frame-tomodel camera tracking and windowed ...

Parallel Generalized Thresholding Scheme for Live Dense Geometry from a Handheld Camera

Inspired by recent successes in parallelized optic flow estimation, we propose a variational method which allows to directly estimate dense depth fields from a single hand-held camera in real-time conditions. In particular we show how the central ingredient of the corresponding optic flow method, namely a thresholding scheme, can be generalized to the problem of geometric reconstruction conside...

Image-Based Rendering from Handheld Cameras Using Quad Primitives

In this paper we will present a novel approach of using surface patches for Image Based Rendering. Based on image sequences acquired with a freely moving portable multi-camera-rig we can extrapolate novel views of complex real scenes in realtime. The cameras are calibrated from the image sequence itself and dense depth maps are computed for each camera view using an improved multiview depth est...

Model-Assisted 3D Face Reconstruction from Video

This paper describes a model-assisted system for reconstruction of 3D faces from a single consumer quality camera using a structure from motion approach. Typical multi-view stereo approaches use the motion of a sparse set of features to compute camera pose followed by a dense matching step to compute the final object structure. Accurate pose estimation depends upon precise identification and ma...

Visual-Geometric Scene Reconstruction from Image Streams

Visual-geometric scene reconstructions capture the visual appearance and geometry of real 3D scenes from image streams. Depending on the type of camera motion and type of scene structure, either 2D od 3D representations can be used. From the representations one can render new views of the scene with high degree of realism. Recently we see a lot of research in this field, especially for the case...
