NYU-VPR: Long-Term Visual Place Recognition Benchmark with View Direction and Data Anonymization Influences

IROS 2021poster

Visual place recognition (VPR) is critical in not only localization and mapping for autonomous driving vehicles, but also assistive navigation for the visually impaired population. To enable a long-term VPR system on a large scale, several challenges need to be addressed. First, different applicatio…
