MonoDiffusion: Self-Supervised Monocular Depth Estimation Using Diffusion Model

1 code implementation13 Nov 2023 Shuwei Shao, Zhongcai Pei, Weihai Chen, Dingchi Sun, Peter C. Y. Chen, Zhengguo Li

Because the depth ground-truth is unavailable in the training phase, we develop a pseudo ground-truth diffusion process to assist the diffusion in MonoDiffusion.

IEBins: Iterative Elastic Bins for Monocular Depth Estimation

1 code implementation NeurIPS 2023 Shuwei Shao, Zhongcai Pei, Xingming Wu, Zhong Liu, Weihai Chen, Zhengguo Li

To alleviate the possible error accumulation during the iterative process, we utilize a novel elastic target bin to replace the original target bin, the width of which is adjusted elastically based on the depth uncertainty.

StairNetV3: Depth-aware Stair Modeling using Deep Learning

no code implementations13 Aug 2023 Chen Wang, Zhongcai Pei, Shuang Qiu, Yachun Wang, Zhiyong Tang

Experiments on our dataset show that our method has a significant improvement over the previous best monocular vision method, with an intersection over union (IOU) increase of 3. 4 %, and the lightweight version has a fast detection speed and can meet the requirements of most real-time applications.

RGB-D-based Stair Detection using Deep Learning for Autonomous Stair Climbing

no code implementations2 Dec 2022 Chen Wang, Zhongcai Pei, Shuang Qiu, Zhiyong Tang

Specifically, we design a selective module, which can make the network learn the complementary relationship between the RGB map and the depth map and effectively combine the information from the RGB map and the depth map in different scenes.

SMUDLP: Self-Teaching Multi-Frame Unsupervised Endoscopic Depth Estimation with Learnable Patchmatch

no code implementations30 May 2022 Shuwei Shao, Zhongcai Pei, Weihai Chen, Xingming Wu, Zhong Liu, Zhengguo Li

Unsupervised monocular trained depth estimation models make use of adjacent frames as a supervisory signal during the training phase.

Towards Comprehensive Monocular Depth Estimation: Multiple Heads Are Better Than One

no code implementations16 Nov 2021 Shuwei Shao, Ran Li, Zhongcai Pei, Zhong Liu, Weihai Chen, Wentao Zhu, Xingming Wu, Baochang Zhang

In this work, we investigate into the phenomenon and propose to integrate the strengths of multiple weak depth predictor to build a comprehensive and accurate depth predictor, which is critical for many real-world applications, e. g., 3D reconstruction.
