Two-dimensional cable data based three-dimensional cable model generation method

Abstract

The invention relates to the technical field of the power cable data processing, particularly to a two-dimensional cable data based three-dimensional cable model generation method. The two-dimensional cable data based three-dimensional cable model generation method comprises the following steps of collection and sorting of underground resource data; model generation which comprises establishment of a model base and generation of a cable chute model; model adjustment which comprises inspection and modification and improvement of error of the two-dimensional data and actual data; rendering of the model which comprises generation of an image through the adjusted model through a software. The two-dimensional cable data based three-dimensional cable model generation method has the advantages of solving problems that underground resource modelling requires ground breaking and material collection is limited; being fine in model accuracy and high in integrity; establishing technical bases for establishment of the three-dimensional model of equipment with data difficult to collect, improving the utilization rate of cable chute resources and achieving refined and intensive management of a cable chute.

[0002] With the continuous development of the scale of the power grid, the proportion of power cables in distribution lines continues to increase. The traditional management model can no longer meet the requirements of reasonable planning, scientific management, and high-quality service. However, while the power grid is developing, power cables have the following problems : First, there is a lack of fault analysis means, and the efficiency of troubleshooting is low; second, it is impossible to grasp the overall picture of the power cable trench, and the planning and design work is difficult. The existence of these problems makes it difficult for the safe operation and maintenance of the power grid. It caused great difficulties and affected the further rational planning and construction of power cable trenches

[0003] In the existing technology, the 3D visualization management of 3D technology is indispensable to the 3D model modeling of the management equipment. In the 3D space system, the existing 3D modeling technology is used to accurately describe things to realize the true reproduction of 3D objects. It gives users an immersive feeling, but the current mainstream modeling methods are manual on-site data collection and assisted laser modeling for model building, but it has always been difficult to collect underground environmental information, and generally only The collection can only be carried out when the resources are newly constructed or renovated. To collect the completed cable trench resources, the soil needs to be broken to collect. At the same time, due to the long laying distance of the cable lines, the workload of collecting all the information of the cables is heavy, which causes the power grid company to deal with the underground. Resource modeling has significant limitations
