Embodiment Construction
[0041] The embodiment of the present application provides a method and device for collecting temperature of electric equipment, which is used to solve the problem that when the existing inspection robot detects the target electric equipment by area at the inspection point, it will detect other objects other than the target electric equipment. The temperature of the object, and without distinguishing the temperature of the target power equipment and other background objects, the temperature of all pixels on the infrared image is compared with the alarm temperature threshold, resulting in technical problems of false alarms.
[0042] In order to make the purpose, features and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the following The described emb...

The invention discloses a temperature acquisition method and device for power equipment. The method comprises the following steps: acquiring an infrared image of which the temperature is to be measured; performing edge detection and image segmentation processing on the infrared image to be subjected to temperature measurement to obtain a plurality of edge images; performing feature extraction on the edge image through the Hu invariant moment to obtain a to-be-identified feature vector; according to a preset feature vector, identifying the plurality of to-be-identified feature vectors through anearest neighbor classifier to obtain a first to-be-identified feature vector matched with the preset feature vector, wherein the preset feature vector is obtained by performing feature extraction onthe target power equipment; acquiring the temperature of an edge image corresponding to the first to-be-identified feature vector, and obtaining a plurality of temperature values of the target powerequipment. According to the invention, the technical problem of false alarm caused by comparison of the temperatures of all pixel points on an image with an alarm temperature threshold value when an existing inspection robot detects the target power equipment on an inspection point location according to regions is solved.
Description
technical field [0001] The present application relates to the technical field of power equipment monitoring, in particular to a method and device for collecting temperature of power equipment. Background technique [0002] With the development of the power grid and the continuous deepening of the reform of the power system, the degree of automation of the power system has been greatly improved. In terms of inspection of substations, the use of inspection robots to conduct intelligent inspections of power equipment in the stations has gradually become large-scale. The inspection robot can take visible light images and infrared image detection of power equipment according to the inspection points, identify meter readings and knife switch openings and closings in visible light images through image recognition technology, and detect the status of power equipment through infrared temperature measurement technology. Temperature, when the temperature reaches the alarm threshold, an...
