To address the issue of reduced robustness in visual place recognition (VPR) caused by domain shift, Shunpeng Chen et al. proposed the AdaptVPR framework. This approach utilizes a visual language model to parse scene attributes and evaluate edit feasibility, and combines a rule-based scheduler to generate three complementary types of difficult positive samples: global appearance routes (changing weather, lighting, and time), local occlusion routes (inserting dynamic occlusions), and dual routes (combining both). The generated candidate images are filtered through geometric consistency and appearance diversity; if failed, optimization is provided. Based on this, the AdaptCities dataset containing 160,000 verified synthetic data was constructed. Experiments show that this method achieves performance improvements in multiple benchmark tests and challenging domain shift scenarios, with a maximum R@1 gain of 9.2%. The related code and data are available publicly.

Development of the AdaptVPR framework and dataset construction
Shunpeng Chen et al. proposed the AdaptVPR framework, using a visual language model and a rule-based scheduler to generate difficult positive samples for three complementary routes (global appearance, local occlusion, dual routes), and constructed a collection containing 160,000 validated synthetic data pieces.
Visual Place Recognition (VPR) robustness often declines due to domain offset. AdaptVPR proposes a generative enhancement framework for route perception to address the issue of insufficient visual diversity at the same location. This framework utilizes a visual language model to parse scene attributes and evaluate editing feasibility, combining a rule-based scheduler to determine the generated route. The process is divided into three complementary modes: global appearance, local occlusion, and dual routes. Generated candidate images are screened using a VPR validation scheme based on geometric consistency and appearance diversity; if the validation fails, global candidates are rejected or local/dual route candidates are suggested for optimization. Based on this, the AdaptCities dataset containing 160K validated synthetic data was constructed. Experiments show that this method achieves consistent improvement in multiple benchmark tests and under challenging domain offset conditions, with a maximum R@1 gain of 9.2%. The relevant code and data are available publicly.
