Existing rotated object detectors rely on box-level IoU prediction to assess localization quality; however, such metrics exhibit structural coupling with ground-truth localization accuracy, leading to systematic overestimation of low-quality predictions. To address this, we propose Pixel-level Quality Assessment (PQA), a novel framework that abandons box-level IoU regression and instead models the spatial consistency between predicted and ground-truth rotated bounding boxes in pixel space—enabling decoupled and robust localization quality estimation. PQA employs a spatial consistency aggregation mechanism to produce a unified quality score and can be seamlessly integrated as a plug-and-play module into mainstream rotated detectors. Extensive experiments on HRSC2016 and DOTA demonstrate substantial improvements: PQA boosts Rotated RetinaNet’s AP$_{50:95}$ by 5.96% and reduces standard deviation (STD) by 2.32%, validating both the effectiveness and generalizability of pixel-level quality modeling.
