The Study Of Three-dimensional Safety Warning System Based On Stereo Vision Technology

With the increasing demand for power development and electricity supply reliability,power supply units must minimize the outage time. Thus in the electrical equipment repairand maintenance process, the live working more and more, maintenance personnel andengineering vehicle operating in the vicinity of high-voltage energized equipment will bemore and more common. Must be real-time monitoring to ensure safety in production,maintenance, engineering vehicles and live equipment a safe distance. Traditional infrared,ultrasonic plane blockade monitoring methods, has been unable to meet the monitoringrequirements of three-dimensional space distance. To this end, the introduction ofthree-dimensional computer vision, high-speed wireless network, directional ultrasonicranging technology to build a new set of three-dimensional space from the monitoring alarmsystem.Three-dimensional monitoring of the job site, in the field of three-dimensionalarrangement of a number of real-time image capture processing terminal, placed in theperipheral appropriate location of the live equipment level, the benchmark for the verticalruler, also equipped with a processing host. Processing terminal configured camera grab thescene in real time from a different spatial location of multi-angle images, and imagesharpening, edge detection, image recognition, and other operations, the processed imagereturns to the processing host. The host processing for image matching, three-dimensionalimage restoration, three-dimensional space spacing scanning algorithm processing, real-timescanning the job site each object and the charged device space minimum distance. When thedistance is close to or less than the alarm distance, timely audible and visual alarms, and faultinformation uploaded to the monitoring center of the formulation specified.3D security alert system put into operation, will improve the safety in the construction ofaround energized equipment, to reduce personal security incidents, and improve the reliabilityof power system operation.
