Visual examination of the workplace and in-time reminder to the failure of wearing a ,safety helmet, is of particular importance to avoid injuries of workers at the construction site. Video monitoring systems provide a large amount of unstructured image data on-site for this purpose, however, requiring a computer vision-based automatic solution for real-time ,detection,.

little researches about ,detection, of ,safety helmet, wearing in power substation. In , the Kalman ﬁltering and Cam-shift algorithm are used to track pedestrians and determine motion objects. Meanwhile, the color information of ,safety helmets, is used to detect ,safety helmets, wearing. The main purpose of this paper is to develop an innovative
This current study is an extension of previous studies in the field of construction ,safety, visualization, computer vision, ,pattern recognition,, and Internet transmission [13–16]. The tool was developed using an image processing method to detect the face of a worker and then used edge ,detection, program and segmentation methods to identify whether the worker had a hard hat.
