基于Faster-RCNN的站台端部人员入侵检测研究

铁路客运站的站台端部为非封闭式环境,存在人员非法入侵的风险。在阐述Faster-RCNN算法原理的基础上,详细描述了VGG16模型、RPN网络以及分类回归的过程。采集现场数据制作样本集,训练了可区分普通人员、施工人员以及防护人员的站端入侵检测模型。测试分析了5组不同参数下的实验数据,确定候选区队列长度等于300,推荐候选区数量等于15时为最优参数。模型对普通人员、施工人员以及防护人员3种样本的识别精确率分别为95%、99%、100%,识别召回率分别为97%、99%、100%,平均精确率均值为0.983 6,单帧检测时间为0.069 s。结果表明:算法可有效地检测普通人员、施工人员以及防护人员,满足实时检测需求,为站台端部人员入侵检测提供了新思路。

Personnel intrusion detection of platform end based on Faster-RCNN

The platform ends of the railway passenger station are non closed environment, which has the risk of illegal invasion.On the basis of explaining the principle of Faster-RCNN algorithm, this paper described the VGG16 model, RPN network and classified regression process in detail.The paper collected field data to make a sample set, and trained the station end intrusion detection model which could distinguish ordinary personnel, construction personnel and protection personnel.Five groups of experimental data with different parameters were tested and analyzed.It was determined that when the queue length of candidate area was equal to 300 and the number of recommended candidate area was equal to 15, it was the optimal parameter.The recognition accuracy rate of the model for ordinary personnel, construction personnel and protection personnel was 95%, 99% and 100%, the recognition recall rate was 97%, 99% and 100%, the average accuracy rate was 0.983 6, and the single frame detection time was 0.069 s.The results show that the algorithm can effectively detect ordinary personnel, construction personnel and protection personnel, meet the needs of real-time detection, and provide a new idea for platform end personnel intrusion detection.
