Electrified interval mistaken entry prevention detection method, medium and system

Abstract

The invention discloses a charged interval mistaken entry prevention detection method, a medium and a system. The method comprises the following steps: arranging a binocular camera around an electrified interval, and acquiring a left eye image and a right eye image around the electrified interval in real time by adopting the binocular camera; tracking angular points in the left-eye image in real time, and determining the number of the angular points of which the positions are changed; if the number of the angular points of which the positions are changed reaches a set threshold value, determining that a moving target appears; determining an area where the moving target is located; matching the detected feature points of the left-eye image and the right-eye image; calculating the depth of a feature point according to the horizontal coordinates of the feature point matched with the left-eye image and the right-eye image and located in the area where the moving target is located; calculating the average value of the depths of all the feature points of the area where the moving target is located to obtain the distance between the moving target and the electrified interval; and if the distance is smaller than the preset safety distance, marking the moving target. The method is stable and objective in detection, and missed detection or false detection is not liable to occur.

Description

technical field [0001] The invention relates to the technical field of electrified compartment safety, in particular to a detection method, medium and system for anti-mis-entry of electrified compartment. Background technique [0002] In today's society, the rapid development of various technologies is inseparable from the support of electric power, and at the same time, it is putting more and more pressure on electric power equipment, so the maintenance of electric power equipment is particularly important. In recent years, in the safety accidents of the power system, casualties caused by mistakenly entering the electrified interval have occurred from time to time, largely due to the weak safety awareness of the operators, and there is no alarm prompt device before the personnel enter the electrified interval by mistake. caused by increased vigilance. The anti-mis-entry detection system can detect the moving targets around the electrified interval in time, and send out an ...
