Problems solved by technology
Although the Pixel2Mesh model can be used to generate a 3D mesh model of power equipment, its shortcoming is that when the Pixel2Mesh model uses a single frame image to generate a 3D mesh model, there is a lack of equipment information due to the shooting angle of the single frame image. This leads to low accuracy of the generated 3D mesh model

The invention provides a three-dimensional grid model generation method and device, electronic equipment and a readable storage medium, belongs to the field of electric power, and aims at improving the three-dimensional grid model generation precision. The image processing method for the power equipment comprises the following steps: collecting at least two equipment images of to-be-processed equipment from a server; determining a standard image and an auxiliary image according to the standard direction and the shooting direction corresponding to each equipment image; generating a three-dimensional grid model corresponding to the standard image, and using the three-dimensional grid model as a standard model to calculate a gray difference mean value of gray-scale maps corresponding to all the equipment images; carrying out median filtering processing on the auxiliary image according to the gray difference mean value; generating a three-dimensional grid model corresponding to each auxiliary image after median filtering processing as an auxiliary model; According to the auxiliary model and the shooting direction of the corresponding auxiliary image, optimizing the standard model to obtain a target model. According to the technical scheme, the generation precision of the three-dimensional grid model can be improved.
Description
technical field [0001] The invention belongs to the field of electric power, and in particular relates to a three-dimensional grid model generation method, device, electronic equipment and readable storage medium. Background technique [0002] In recent years, with the rapid development of the power grid, the scale of the power grid has gradually expanded and the accumulation of massive power grid operation data, the power grid system has been committed to building a 3D scene model of the power grid based on the 3D grid model of the power equipment to support fault analysis and simulation training of regulation and control faults. [0003] Since a large number of 3D grid models of power equipment need to be constructed in advance when constructing a 3D power scene model, it is time-consuming and labor-intensive to build a 3D power scene model; while the equipment images of power equipment stored in existing power grid storage systems are basically two-dimensional images, If ...
