Dynamic three-dimensional modeling method for underground cable

Abstract

The invention discloses a dynamic three-dimensional modeling method for an underground cable. The dynamic three-dimensional modeling method comprises the steps of sorting data; performing a second round of content information extraction on all underground cable service data; performing conditional storage operation on the target data; after data storage is completed, fusing the processed multi-source data, formulating standard specifications of three-dimensional cable and channel space data, constructing an automatic modeling scheme, standardizing making of three-dimensional model data, and completing automatic modeling of a three-dimensional model on the premise that the accuracy and precision of the model are guaranteed. According to the invention, the conventional archiving storage mode is simplified and reduced, the efficiency of querying the internal logic of the data is better improved, and the supporting capacity is better provided for automation construction; and the three-dimensional model of the underground cable is established more accurately, the three-dimensional model of the underground cable equipment facility can be established accurately by combining spatial features and description information according to geometric and physical characteristics of an object, and the result quality is improved.

Description

technical field [0001] The invention belongs to the technical field of modeling, and in particular relates to a dynamic three-dimensional modeling method for underground cables. Background technique [0002] With the continuous acceleration of the urbanization process, the application rate of power cables in cities is getting higher and higher. Various underground pipelines are arranged under the whole city in a complex and disorderly manner at various depths, making it difficult to build new power cable channels. getting bigger. During the implementation of the project, there are often situations where the planned power channel conflicts with the existing pipeline, and it cannot be implemented, and the route needs to be re-selected, or the cable space position is unreasonable, and the cable length is inaccurate, which brings inconvenience to the construction and greatly increases the project cost. waste. It is necessary to innovate and optimize technical means to solve th...

Problems solved by technology

[0004] The manual modeling method has a huge workload, low efficiency, uneven quality of artificially produced materials, extremely low modeling accuracy, and consumes a lot of human resources. Only relying on manual recognition is bound to be inefficient, and there are a lot of problems when dealing with large amounts of data. Human error, basically not suitable for large volume and fast processing work

[0005] In principle, the remote sensing measurement modeling method uses fast image matching technology to generate DOM, which requires manual or semi-automatic collection of artificial ground objects to obtain the image of building surface textures. The technology has limitations in objective practical applications. The occlusion problem of the model is serious, the cost of obtaining the texture data of the building facade is high, and the texture of the interior is time-consuming and laborious
