TSDF-Sampling: Efficient Sampling for Neural Surface Field using Truncated Signed Distance Field

no code implementations29 Nov 2023 Chaerin Min, Sehyun Cha, Changhee Won, Jongwoo Lim

Notably, our method is the first approach that can be robustly plug-and-play into a diverse array of neural surface field models, as long as they use the volume rendering technique.

OmniSLAM: Omnidirectional Localization and Dense Mapping for Wide-baseline Multi-camera Systems

no code implementations18 Mar 2020 Changhee Won, Hochang Seok, Zhaopeng Cui, Marc Pollefeys, Jongwoo Lim

In this paper, we present an omnidirectional localization and dense mapping system for a wide-baseline multiview stereo setup with ultra-wide field-of-view (FOV) fisheye cameras, which has a 360 degrees coverage of stereo observations of the environment.

OmniMVS: End-to-End Learning for Omnidirectional Stereo Matching

2 code implementations ICCV 2019 Changhee Won, Jongbin Ryu, Jongwoo Lim

The 3D encoder-decoder block takes the aligned feature volume to produce the omnidirectional depth estimate with regularization on uncertain regions utilizing the global context information.

SweepNet: Wide-baseline Omnidirectional Depth Estimation

1 code implementation28 Feb 2019 Changhee Won, Jongbin Ryu, Jongwoo Lim

Omnidirectional depth sensing has its advantage over the conventional stereo systems since it enables us to recognize the objects of interest in all directions without any blind regions.
