Ziyi Zhang, Changfei Kong, Jiafa Mao, Xu Cheng, Sixian Chan · 2024
Multi-view stereo (MVS) has emerged as a pivotal algorithm in 3D reconstruction, garnering significant research attention over the past several decades. While recent coarse-to-fine methods have demonstrated promising results in enhancing the reconstruction quality of traditional algorithms, they often neglect the crucial aspect of feature layer refinement. Additionally, these methods face the challenge of low-cost feature matching. To address these limitations, we propose a novel learning-based MVS framework(EE-MVSNet). Firstly, we propose a novel approach incorporating an explicit visual center (EVC) module within the feature pyramid network (FPN), strengthening the adjustment within feature layers and improving model accuracy. Furthermore, we introduce the ECA+3DCNN module, which utilizes channel attention to alleviate the problem of low-cost feature matching. Finally, our model achieves competitive performance through extensive experimentation on the DTU dataset, showcasing its high-quality 3D reconstruction.
