POLAR introduces a method for multiview point cloud registration by performing alignment in an autoencoder's latent space, rather than directly in the ambient space. This approach, developed by the ICube Laboratory, enhances robustness to noise, occlusions, and outliers, and was shown to achieve higher success rates on degraded synthetic data and effectively register challenging real-world SMLM data.
Key insights
- Performing registration in a learned latent space provides robust and compact point cloud representations, improving resilience to data degradation.
- Jointly optimizing a latent code for the complete object and individual view poses allows for simultaneous consideration of all views, avoiding error accumulation typical in pairwise methods.
- Explicitly modeling and accounting for data degradations like occlusions, outliers, and anisotropic noise within the loss function enhances performance in challenging real-world scenarios.
