I am currently a fourth-year Ph.D. student (2022 – now) in the Department of Automation, University of Science and Technology of China (USTC), advised by Prof. Tianzhu Zhang and Prof. Baoqun Yin. I spent my M.Eng. studies at the Advanced Technology Research Institute, USTC. Huazhong University of Science and Technology conferred upon me a B.Eng. degree in 2020 from the School of Electrical and Electronic Engineering. My research interests include computer vision, multimodal learning and 3D vision.

Adaptive Agent Selection and Interaction Network for Image-to-Point Cloud Registration

Zhixin Cheng, Xiaotian Yin, Jiacheng Deng, Bohao Liao, Yujia Chen, Xu Zhou, Wenfei Yang*, Baoqun Yin

This paper targets the challenges of image-to-point-cloud registration under noise, where false correspondences are common and cross-modal information is difficult to filter effectively. It proposes a framework composed of Iterative Agent Selection and Reliable Agent Interaction: phase maps enhance structural perception, and reinforcement learning selects more reliable agents to guide cross-modal interaction, thereby reducing mismatches and improving robustness.

CA-I2P: Channel-Adaptive Registration Network with Global Optimal Selection

Zhixin Cheng, Jiacheng Deng, Xinjun Li, Xiaotian Yin, Bohao Liao, Baoqun Yin, Wenfei Yang*, Tianzhu Zhang

This paper addresses detection-free image-to-point cloud registration, where cross-modal channel mismatches and redundant top-k correspondences reduce matching quality. CA-I2P uses a Channel Adaptive Adjustment module to align channels across modalities and a Global Optimal Selection module to produce globally consistent matches for robust registration. We attend the conference and discussed our ideas with Google AI scientist Martin Sundermeyer.

Bridge 2D-3D: Uncertainty-aware Hierarchical Registration Network with Domain Alignment

Zhixin Cheng, Jiacheng Deng, Xinjun Li, Baoqun Yin, Tianzhu Zhang*

This paper proposes B2-3Dnet for detection-free image-to-point cloud registration, aiming to reduce distraction from noisy image patches and narrow the cross-modal domain gap. It introduces an uncertainty-aware hierarchical matching module that estimates patch reliability and performs multi-scale coarse-to-fine interactions, and an adversarial modal alignment module that aligns image and point-cloud features using a gradient reversal strategy and a domain classifier.
