The invention provides an insulator creepage distance measurement method and device, electronic equipment and a storage medium. The measurement method comprises the following steps: acquiring a scanning image of a to-be-measured insulator; inputting the scanning image into a pre-trained image extraction model, and outputting a marker image; and performing division calculation on the marker image to obtain the length of the marker, and determining the length of the marker as the creepage distance of the insulator to be measured. By adopting the technical scheme provided by the invention, the scanning image of the insulator can be acquired through the three-dimensional scanning equipment, the marker attached to the insulator is extracted by using the pre-trained image extraction model, the length of the marker is calculated, and the length of the marker is determined as the creepage distance, so that non-contact insulator creepage distance measurement is realized, and the measurement accuracy of the insulator creepage distance is improved. And the efficiency and the accuracy of creepage distance measurement are improved.
Description
technical field [0001] The present application relates to the technical field of three-dimensional measurement, and in particular, to a method, device, electronic device and storage medium for measuring creepage distance of insulators. Background technique [0002] The insulator creepage distance refers to the shortest distance or the sum of the shortest distances along its surface between the conductive parts to which the operating voltage is normally applied. Under different usage conditions, the insulator is charged due to the electrical polarization of the insulating material around the conductor. Whether the creepage distance of the insulator meets the standard has a profound impact on the life safety of the operator. [0003] The surface of the insulator is smooth and consists of multiple arcs. It is difficult to measure the creepage distance. At present, the creepage distance of the insulator is mainly measured manually, which is difficult to operate and inefficient....
