摘 要: | 为改善现有变电站巡检人员不规范佩戴安全帽检测时效率、精度低的问题,提出一种基于改进YOLO 的
轻量化变电站人员不规范行为检测模型。该模型由特征提取网络、ECA-SPP 和ECA-PANet 网络以及预测网络组成;
特征提取网络中使用MobileNetV3;提取4 个尺度的特征图并将其输入到SPP 和PANet 网络中,并基于注意力机制
进行优化;以建立的变电站人员不规范佩戴安全帽检测数据集为例,验证所提模型有效性。实验结果表明:所提模
型mAP 为0.824 4,FPS 为38.06,明显优于Faster RCNN、YOLOv4、YOLOx 等模型,具有较高精度和更快的检测
速度,可为变电站人员不规范佩戴安全帽的实时检测提供参考。

Detection of Nonstandard Wearing of Safety Helmet Based on Improved YOLO |
| |
Abstract: | In order to solve the problem of low efficiency and accuracy in the detection of non-standard safety helmet
worn by the existing substation patrol personnel, a lightweight substation personnel non-standard behavior detection
model based on improved YOLO is proposed. The model consists of a feature extraction network, an ECA-SPP network,
an ECA-PANet network and a prediction network; MobileNet V3 is used in the feature extraction network; feature maps
of four scales are extracted and input into the SPP and PANet networks, and are optimized based on an attention
mechanism; The effectiveness of the proposed model is verified by the data set of the detection of non-standard wearing
of safety helmets in substations. The experiment results show that the proposed model mAP is a 0.8244 and FPS is a
38.06, which is obviously better than other models such as Faster RCNN, YOLOv4 and YOLOx, and has higher accuracy
and faster detection speed. It can provide a reference for real-time detection of substation personnel wearing
non-standard safety helmet. |
