Abstract

The invention relates to a power grid image positioning method and an image positioning model training method. The method comprises: obtaining coordinate information of a first-level positioning object in the power grid image and a corresponding mask image through a first-level positioning network in a predetermined machine learning model; obtaining a cut image of the first-level positioning object according to the coordinate information; jointly determining coordinate information corresponding to a second-level positioning object in the cut image through a second-level positioning network according to the mask image and the cut image; and finally, positioning the object in the power grid image according to the coordinate information. Firstly, a first-level positioning object in a power grid image is positioned through a first-level positioning network in an image positioning model; and then a second-level positioning object in dependence connection with the first-level positioning object in the cut image is positioned through a second-level positioning network, so the method can achieve the positioning from the first-stage positioning object to the second-stage positioning objectunder the condition that the size of the object is smaller, and is very suitable for the object detection and recognition in a scene that the size difference of the object on a power transmission lineis larger.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a grid image positioning method, an image positioning model training method, a device, a computer-readable storage medium and computer equipment. Background technique [0002] Most of the transmission lines are laid in places with inconvenient transportation, and the working conditions of the maintenance personnel are relatively difficult, and the components of the transmission equipment on the transmission lines are usually damaged due to a series of factors such as time and climate. Nowadays, during each power transmission inspection and substation inspection, it is possible to collect grid images of transmission lines, such as aerial grid images or drones to collect grid images, and then check the grid images to determine the transmission line. Grid security. [0003] In the traditional way, it is usually through manual inspection to observe the grid image and det...
