The foregoing is a detailed description of a first embodiment of a method for constructing a three-dimensional visualization system for a power grid provided in the present application, and the following is a detailed description of a second embodiment of a method for constructing a three-dimensional visualization system for a power grid provided in the present application.
In this embodiment, further, referring to fig. 2, step S200 specifically includes steps S201 to S203, and details are as follows:
s201, identifying importance of the power equipment according to the asset information;
the type of the electric power equipment in the asset information can be judged, such as a telegraph pole, a distribution box and the like, and obviously, the function and the importance of the distribution box in power grid transmission and transformation are greater than those of the telegraph pole; in this embodiment, the identification may be completed by using a preset power equipment importance comparison table;
carrying out gridding treatment on the three-dimensional model according to the importance of the power equipment; acquiring corresponding Beidou grid codes according to the longitude and latitude of the power equipment and the Beidou grid code level;
setting the space grid density of the power equipment according to the importance of the power equipment
S202, carrying out gridding processing on a space where the power equipment is located according to the position information and the importance of the power equipment, wherein the higher the importance of the power equipment is, the denser the grids are in gridding processing, and determining Beidou grid codes corresponding to the power equipment under the position information;
it should be noted that, the beidou grid code divides the whole earth space into megahundred million grid bodies, under the 32-level grid division system, the 15-bit grid code represents a certain grid of 1 meter on the earth, and the 19-bit grid code represents a certain grid of 1.5 cm on the earth; the denser the grids are after the gridding treatment, the higher the number of the set Beidou grid codes is, the higher the level is, and the more information can be represented;
therefore, on the basis of saving the data quantity and improving the display precision of important power equipment, high-level Beidou grid codes are not needed to be adopted for the power equipment which is not important such as a telegraph pole, the space and the environment where the Beidou grid codes are positioned contain less information influencing a power grid, and the data processing amplitude can be reduced to save the data quantity; for important power equipment such as a distribution box, a high-level Beidou grid code with smaller side length is adopted, so that denser grids can have more information, and the content which can be expressed by a subsequently constructed visual system is richer;
s203, marking the Beidou grid code on asset information, size information, shape information and environment information.
The more important power equipment has more grids spanned by size information, shape information and environment information, so that the more Beidou grid codes are marked, the more the association relation between data information is tight, and the more accurate the association relation is in the visual expression of the three-dimensional map.
Further, after labeling the Beidou grid code on the asset information, the size information, the shape information and the environment information, the method further comprises the following steps: identifying the size information quantity of the same Beidou grid codes, if the size information quantity exceeds a preset threshold value, performing secondary grid processing on a space corresponding to the size information, and resetting the Beidou grid codes; when the number of the size information of the same Beidou grid code exceeds a threshold value, the structural complexity of the power equipment in the space grid is not matched with the current grid size; the condition that the size information quantity exceeds the threshold value can be that the size information quantity is larger than an upper limit threshold value or smaller than a lower limit threshold value, for example, instrument and instrument equipment and shell structures in the distribution box are correspondingly distributed, the Beidou grid codes are further adjusted, the information richness of key areas of the power grid visualization system is improved, the information redundancy of non-important areas is reduced, and the data processing capacity of the system is reduced.
Further, in the foregoing step S300, before converting the size information and the shape information into the three-dimensional base map through data conversion, the method further includes: identifying size information and structure information representing the same power equipment according to the asset information, and integrating the information of the same power equipment; and constructing a three-dimensional model based on the size information and the shape information, and taking the three-dimensional model as a three-dimensional base map.
When the names and models of the power equipment in the asset information are the same, the corresponding size information and structure information can be the same as the three-dimensional model, and only the position information is different, so that the same model can be adopted for the same power equipment when the three-dimensional base map is converted, and then the same model is positioned, so that the data conversion efficiency is improved;
further, in the foregoing step S300, after rendering the three-dimensional base map according to the asset information and the environment information, the method further includes:
removing the colors of the model in the rendered three-dimensional base map, and converting the colors into gray scales; identifying different power equipment with the same Beidou grid code or adjacent different power equipment, and judging whether the gray value difference value of the corresponding model in the rendered three-dimensional base map is larger than a preset gray threshold value or not; if yes, correcting the gray value of the model in the three-dimensional base map.
It should be noted that, the colors in the three-dimensional base map are related to the aesthetic degree of the model, and the colors are converted into gray values from the colors RGB after being removed, so that the stability of the system is not reduced, the amplitude of the model data to the system is reduced, and the information processing efficiency is improved;
the electric power three-dimensional visualization system needs to be displayed to a manager, so that in order to ensure that different electric power equipment can be distinguished by naked eyes of a person, the gray level difference value of the mutually-attached and adjacent models needs to be larger than a preset gray level threshold value so as to be convenient for distinguishing; the gradation threshold value is set to thirty in this embodiment.
Further, in the step S100, before acquiring and analyzing the multidimensional heterogeneous power grid data, the method further includes: performing quality inspection and preprocessing on multidimensional heterogeneous power grid data; for oblique photographic images and third-party geographic feature data, the format quality of the data is difficult to control and is related to the specifications of an aerial photographing machine and the standard provided by the third-party data, so that quality inspection and pretreatment of acquired data are required to be carried out in order to ensure the quality of a subsequent three-dimensional visualization system; for photographic images and geographic feature data such as: checking contents such as image overlapping degree, photo inclination angle, rotation angle, route curvature, shooting area coverage, image definition, image point displacement and the like, setting a preset standard, and when any preset standard data cannot be achieved, re-shooting and collecting according to actual conditions; and preprocessing the size information, the shape information, the position information and the environment information, and eliminating incomplete noisy data.
