NLOS-OT通过多种嵌入和优化传输,在复杂场景中实现被动NLOS成像,通过实验证明了这个NLOS-OT方法比现有的端到端训练框架性能更好。 实验证明了漫射投影图像,即便使用手机摄像头拍摄的图像也包含了足够的场景信息在里面,当使用具有未知遮挡的广泛分布数据进行训练时,NLOS-OT可以在完全不同的数据集上完成测试,这表明NLOS-T...
Non-line-of-sight (NLOS) imaging is a rapidly developing research direction that has significant applications in autonomous vehicles, remote sensing and other areas. Existing NLOS methods primarily depend on time-gated measurements and sophisticated sign
在这种情况下,我们称之为非视域(NLoS)重建问题,在漫反射漫反射的表面上造成的时间和方向信息或多或少的丢失意味着必须以一种截然不同的方式来处理这个问题。 二、研究现状 在文献中提出的技术改造对象几何和反射率three-bounce间接测量组合方法[1]...
Non-line-of-sight (NLOS) imaging aims at reconstructing targets obscured from the direct line of sight. Existing NLOS imaging algorithms require dense measurements at regular grid points in a large area of the relay surface, which severely hinders their availability to variable relay scenarios in ...
NLOS 2D姿态估计:文章使用Yang-Ramanan模型来进行2D姿态估计并引入histogram of oriented gradients(HOG)概念,因为原始帧模糊且HOG结构化比较少,所以无法直接使用,需要先进处理热图像。图片模糊是因为物体材料表面的低反射率造成了低信噪比(SNR)从而导致模糊,本文使用2个方法进行去噪: ...
她与大家分享的主题是“Non-line-of-sight (NLOS) Imaging”,届时将介绍NLOS imaging的整体情况、现存挑战难点;她还会详细介绍其团队获得CVPR 2019 Best Paper Award的工作——基于Fermat paths费马路径的理论和算法,并展示利用此算法的NLOS重建实验结果。
Emerging single-photon-sensitive sensors produce picosecond-accurate time-stamped photon counts. Applying advanced inverse methods to process these data has resulted in unprecedented imaging capabilities, such as non-line-of-sight (NLOS) imaging. Rather

Daniele Faccio from the University of Glasgow in the U.K. will present the new findings, titled "Non-Line-of-Sight (NLoS) Imaging and Imaging through Scattering Media," at the Optica (formerly OSA) Imaging and Applied Optics Congress 11–15 July 2022. Faccio will present on Monday, 11 Ju...
Non-line-of-sight (NLOS) imaging has the ability to reconstruct hidden objects from indirect light paths that scatter multiple times in the surrounding environment, which is of considerable interest in a wide range of applications. Whereas conventional imaging involves direct line-of-sight light tran...
