The first comprehensive review of deep learning methods for point cloud denoising is presented, introducing a novel functional taxonomy based on problem modeling strategies. It establishes a unified benchmark for fair evaluation and identifies current challenges and future research directions in the field.

Key insights

• Deep learning approaches have surpassed classical methods by learning complex geometric priors directly from data, becoming the dominant paradigm in point cloud denoising.
• A functional taxonomy, classifying methods by their underlying problem modeling strategies, provides a more insightful understanding of diverse denoising principles than purely architectural distinctions.
• Establishing a unified and reproducible benchmark is critical for fair evaluation, revealing true performance strengths, weaknesses, and facilitating progress in the field.
• Identifying open challenges and outlining future research directions, such as lightweight models and task-aware denoising, is crucial for advancing robust and efficient point cloud solutions.
