To address this need, this paper proposes an image-triangle based multi-view 3D reconstruction (IMGTR) method. Starting from constructing a density-adaptive image triangulation for each image, the main procedure is to determine the corresponding object plane for each image triangle under an ...
Multiview three-dimensional (3D) reconstruction is a technology that allows the creation of 3D models of a given scenario from a series of overlapping pictures taken using consumer-grade digital cameras. This type of 3D reconstruction is facilitated by freely available software, which does not requi...
如上所述,我们在2D中的每一个点都对应到3D空间中的一条射线,虽然我们不知道具体是3D空间中哪一个点,我们可以将一个点的特征”unproject”回这个3D voxel空间中去。然后每个voxel对于所有view的特征进行aggregation,这样相当于每个view提供一些可能的candidate位置,然后不同view之间去做了majority vote。这样我们在这个...
出现了几个图形学中比较多见的术语, iso-surface(等值面), SDF(sign distance function, 有向距离场), Possion Reconstruction(泊松重建), Cube Marching Algorithm... 大致重建3D模型的思路: 假设我们有了深度图, 可以把空间划分为一个个的体素(voxel), 只要可以逐voxel确定: 该voxel 位于 实际3D物体的内部还是...
Given a set of photographs, the goal ofimage-based 3D reconstructionalgorithms is to estimate the most likely 3D shape that explains those photographs. Multi-view stereo (MVS)is the general term given to a group of techniques that use stereo correspondence as their main cue and use more than...

Single/multi view image(s) to voxel reconstruction using a recurrent neural network - chrischoy/3D-R2N2
We introduce the Structural MPI (S-MPI), where the plane structure approximates 3D scenes concisely. Conveying RGBA contexts with geometrically-faithful structures, the S-MPI directly bridges view synthesis and 3D reconstruction. It can not only overcome the critical limi...
Here we show that the Bright-Field (BF) contrast can be efficiently reconstructed in 3D by adopting a multi-view image processing method: we propose to fuse three-dimensional image data sets of the sample acquired at multiple angles into a single reconstruction. Each data set consists of a st...
Creating the Disparity Space Image (DSI)为了保证3D重建的尺度表示范围,将包含目标物体的3D空间沿着相机的运动轨迹分割成更小的空间,分别对其进行reconstruction后再进行merge先介绍局部空间的reconstruction方法,即使用部分event(后用event subset代指)的重建算法。首先,为每个subset选择一个对应的视点并表示为一个虚拟...
