Abstract

The invention relates to an electrician insulating glove real-time detection method and a computer readable medium storing an electrician insulating glove detection program. The method comprises the following steps: detecting whether a pedestrian pattern exists in a frame image or not by employing a deep learning algorithm, and marking the pedestrian pattern by employing a marking box if the pedestrian pattern is detected in the frame image; extracting wrist joint coordinates and elbow joint coordinates corresponding to the pedestrian pattern in the mark frame by using a posture estimation algorithm, and extracting a hand region image in the mark frame according to the wrist joint coordinates, the elbow joint coordinates and a hand extraction graph of the pedestrian pattern in the mark frame; and comparing the gray value of each pixel in a hand region image with the gray threshold of an insulating glove in HSV space to obtain the ratio of pixels with gray values located within the gray threshold range of the insulating glove to the pixels of the hand region image, comparing the ratio with an insulating glove identification ratio threshold, and outputting an insulating glove identification result. According to the invention, the detection efficiency of the insulating gloves of the electrician in the video can be improved.

Description

technical field [0001] The invention relates to the technical field of glove recognition in images, in particular to a real-time detection method for electrical insulating gloves and a computer-readable medium storing a detection program for electrical insulating gloves. Background technique [0002] Object recognition refers to finding a specified object in an image or video and framing the specific location of the object. There are many object recognition algorithms, and the simplest one is to judge only by the color of the object. However, the color is too sensitive to the lighting conditions and the stability is too poor. Later, HAAR and Adaboost were used for face recognition, HOG features for pedestrian detection, SIFT or SURF features for feature matching for target recognition, and so on. However, the recognition rates of these algorithms are easily disturbed by the environment, and the environmental factors of power operations are just complex and changeable. How ...
