针对变电站复杂动态工况下智能巡检机器人定位建图精度衰减问题,提出一种融合改进CA-YOLOv5目标检测的增强型定位与地图构建架构。采用多模态注意力机制优化CA-YOLOv5网络,构建动态目标实时识别框架;通过语义-几何联合约束策略,在特征匹配阶段建立动态区域掩膜与运动概率模型;设计基于时空一致性的动态特征过滤算法,在捆绑调整优化环节实现动态干扰源的精准剔除与静态场景结构的有效保留。在公开数据集与真实动态场景中的对比试验表明,改进系统将动态环境下的定位误差降低43.7%,地图重建完整度提升41.5%,同时维持良好的实时处理性能。融合框架解决动态元素导致的误匹配与地图污染问题,有效克服了变电站典型动态干扰。
To address the degradation in localization and mapping accuracy of intelligent inspection robots under complex and dynamic operating conditions in substations, an enhanced localization and mapping architecture integrating improved CA-YOLOv5 target detection was proposed. A multimodal attention mechanism was used to optimize the CA-YOLOv5 network and construct a real-time dynamic target recognition framework. A semantic-geometric joint constraint strategy was used to establish a dynamic region mask and a motion probability model during the feature matching stage. A dynamic feature filtering algorithm based on spatiotemporal consistency was designed to achieve precise elimination of dynamic interference sources and the effective preservation of the static scene structure in the BA optimization process. Comparative experiments on public datasets and real dynamic scenarios demonstrated that the improved system reduced the localization errors by 43.7% and improved the map reconstruction completeness by 41.5% in dynamic environments, while maintaining satisfactory real-time processing performance. The fusion framework effectively solves the problems of mismatching and map pollution caused by dynamic elements, thereby overcoming typical dynamic disturbances in substations.
