Abstract

The invention provides a hole site protection door state detection method and device, computer equipment and a storage medium. The method comprises steps of starting from image recognition, acquiringan image of to-be-tested equipment to construct a training sample set; obtaining a preset threshold value of a discrimination function straight line according to the training sample set; then, carrying out self-adaptive dynamic threshold segmentation based on local statistics on a newly obtained image of the to-be-detected equipment, accurately screening out the hole site area; projecting extracted gray features of the hole site area to a preset discrimination function straight line to achieve the effects of extracting the classification information and compressing the feature space dimension;wherein after projection, the feature subset has the maximum inter-class distance and the minimum intra-class distance in the subspace after projection; finally, judging whether the to-be-detected equipment has defects or not according to the projection ordinate value of the gray feature subset and the threshold value of the preset discrimination function straight line. The method is convenient,fast, effective, high in accuracy, high in anti-interference capacity and stable in detection result.

Description

technical field [0001] The present application relates to the technical field of equipment status detection, in particular to a method, device, computer equipment and storage medium for detecting the status of a hole protection door. Background technique [0002] The protective door, also known as the safety door, is a kind of safety protection cover. It is generally installed on the hole. When the hole is not used, it blocks the hole and prevents foreign objects from entering the hole, which may pose a safety hazard. Now, there are products with protective doors on the market, such as sockets bought on the market, with safety protection covers inside the socket holes. When plugging in the plug, the protective cover will automatically push away, unplug the plug, and protect the The door will automatically reset the hole of the closed socket, and also include the network cable socket or other electrical equipment holes generally installed on the wall panel, and the protective...
