Zusammenfassung:In the context of industrial robot maintenance and assembly, workers often suffer from work-related musculoskeletal disorders (WRMSDs). This paper proposes a multi-scale, multi-stage pose recognition method (MMARM-CNN) based on convolutional neural networks to provide ergonomic intervention. The method leverages computer vision technology to enable non-contact data acquisition, reducing the interference of physiological and psychological factors on assessment results. Built upon the baseline yolov8-pose framework, the method addresses complex maintenance environments, which are prone to occlusion, by introducing the Lightweight Shared Convolutional Detection Head-pose (LSCD-pose) module, Multi-Scale Channel Attention (MSCA) mechanism, and Efficient Multi-Scale Patch Convolution (EMSPC) module, enhancing the model’s feature extraction capabilities. The MMARM-CNN model was validated using the MS COCO 2017 dataset and robot assembly data collected under laboratory conditions. The experimental results show that the MMARM-CNN achieved an accuracy improvement, reaching 0.875 in the mAP@0.5 evaluation. Overall, this method demonstrates significant potential in advancing the automation and intelligence of ergonomic interventions.
