Problems solved by technology

However, the algorithm is only applicable to convex polyhedrons, so in most cases, it may not be possible to directly run the algorithm to calculate the distance in most cases. It involves the problem of how to divide complex objects into multiple convex polyhedrons, which increases its complexity. Uncertainty

Abstract

The invention discloses a transformer substation three-dimensional model spacing calculation method. The method comprises the following steps of constructing a three-dimensional model; carrying out gridding on the constructed three-dimensional model of the transformer substation; dispersing the three-dimensional model of the transformer substation into vertexes and grids; obtaining respective vertex coordinate arrays of the three-dimensional model of the transformer substation; and calculating the minimum spacing between the three-dimensional models of the transformer substation. The inventionprovides a method capable of quickly and accurately calculating the minimum distance of a three-dimensional model of a transformer substation.

Description

technical field [0001] The invention belongs to the field of three-dimensional model design of substations, and in particular relates to a distance calculation method for three-dimensional models of substations. Background technique [0002] With the development of smart substation and 3D image technology, the information contained in the 3D model is becoming more and more abundant, and the amount of data is also increasing. In the prior art, there are mainly two schemes for calculating the minimum distance between two 3D models: [0003] At present, the time complexity of existing algorithms for calculating the distance between two separated 3D models is at least O(logm+logn). For example, the method of calculating the distance between two 3D models: for two separated 3D models P and Q, the initial search range P' and Q' are calculated in the form of polygon tangent, and then according to the distance between the intermediate vertices of P' and Q' and their associated edge...
