Abstract

The invention discloses a method for transformer substation site selection by using oblique photography modeling. The method comprises the following steps: A, determining the flight height and the flight path of an aviation oblique photography device according to the geomorphological characteristics and the site selection area of a site selection region, and performing oblique photography by the aviation oblique photography device according to the set flight height and the flight path; B, carrying out noise reduction processing on the shot image; C, combining the images subjected to noise reduction processing to obtain a three-dimensional model; D, performing secondary correction on the three-dimensional model; and E, performing transformer substation site selection according to the three-dimensional model. For the method for transformer substation site selection by using oblique photography modeling, the defects in the prior art can be overcome, and the accuracy of modeling by using oblique photography is improved.

Description

technical field [0001] The invention relates to the technical field of civil engineering design, in particular to a method for site selection of substations by using oblique photographic modeling. Background technique [0002] Oblique photographic modeling is a way of using aerial imagery to model a specific area in 3D. It reduces labor costs and increases modeling speed. However, existing oblique photogrammetry modeling methods are not precise enough for modeling detail control. Due to the high requirements for topographic data in the site selection design of substations, the common oblique photographic modeling method cannot be applied to the site selection work of substations. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a substation site selection method using oblique photographic modeling, which can solve the shortcomings of the prior art and improve the accuracy of oblique photographic modeling. [00...
