Outline

This paper presents GC MVSNet plus plus, a novel method that integrates geometric consistency (GC) checks into the training process, unlike existing multi-view stereoscopic (MVS) methods that primarily rely on photometric and geometric consistency constraints. GC MVSNet plus plus accelerates the training process by actively enforcing geometric consistency across depth maps of reference views at multiple views and scales, directly penalizing geometrically inconsistent pixels. Furthermore, we introduce a densely connected cost regularization network with two blocks (simple and feature dense) designed to leverage dense feature connections for improved regularization. It achieves state-of-the-art performance on the DTU and BlendedMVS datasets and ranks second on the Tanks and Temples benchmark.

Takeaways, Limitations

Takeaways:
We significantly improve the learning speed of MVS by incorporating geometric consistency across multiple views and scales into the learning process (by halving the number of learning iterations).
Improved regulatory effectiveness is achieved through a densely connected cost-regulated network.
It achieves state-of-the-art performance on the DTU and BlendedMVS datasets and performs well on the Tanks and Temples benchmarks.
Reproducibility was achieved through public code.
Limitations:
The method presented in this paper does not guarantee optimal performance for all MVS problems. Performance may vary depending on specific datasets or conditions.
The source code may lack details about implementation details or potential computational costs.
A more in-depth comparative analysis with other advanced MVS methods is needed.
