Abnormal object detection and recognition in the complex construction site via cloud computing

For the construction site image understanding, object detection and recognition are the most important tasks. In the construction site with electrical equipment, the scene need to be monitored carefully to avoid accident. In our work, one anomaly detection method via the cloud computation is proposed. The method consists of the one-stage deep learning object detection model and the one-class classification. The one-stage object detection method detects and recognizes the objects in the scenes. Then, the one-class SVM alarms the abnormal region. The proposal algorithm has been tested on several scenes of real construction sites, and achieves fine results practicably.
