Abstract: Accurate acupoint localisation is essential for standardised acupuncture therapy and intelligent systems, yet remains challenging due to soft-tissue variability, ambiguous anatomical boundaries, and cross-domain distribution shifts. This study proposes a unified perception framework that integrates multiple complementary mechanisms within a single localisation pipeline. The proposed ACUR-Net incorporates high-resolution feature representation, geometry-aware relational modelling, uncertainty-aware regression, and domain adaptation to address anatomical variability and domain heterogeneity in a coordinated manner. The underlying assumption is that reliable acupoint localisation benefits from the joint modelling of anatomical topology, cross-domain feature alignment, and prediction uncertainty, rather than from isolated architectural modifications. Experiments conducted on the AcuSim-FAcupoint dataset show that the proposed framework achieves improved feature transfer stability and spatial consistency. Comparative evaluations indicate that ACUR-Net outperforms PFLD, PIPNet, HRNet, and ViTPose in terms of NME, PCK@0.05, and OKS-mAP. The results suggest that multi-factor integration is effective for enhancing localisation robustness under realistic conditions.
