Monitoring Strategy and Application of Protection Area of Live Working

In the original live working process, the staff wears equipotential suit and is monitored by the staff on the ground. A certain degree of visual error makes the job suffer risk. With the development of computer vision technology, using cameras for video capture and intelligent monitoring are widely used in various fields. This article is intended to design a live video monitoring system, using video imaging system instead of vision as a means of entering and computers replace human brain complete processing. Through the establishment of camera imaging model and discussion of camera calibration method to build the conversion relationship between the 3D coordinates of one point on the space object´s surface and the 2D coordinates of the corresponding point on the image. In this way, we can figure out the actual distance of any two space points. According to this principle and the requirements for safe distance in the safety regulations for live working, we can determine the appropriate image alarm area and immediate alarm when workers enter the alarm area. Finally, take advantage of mutual cooperation of multiple cameras to create a three dimensional alarm areas, so the intelligent video surveillance function realized.
