Embodiment

[0050] Embodiment: A method for drawing geographical wiring diagrams of power grids based on aerial image recognition (see Figure 1-Figure 9 ), the specific steps are as follows:

[0051] Step 1. Select the eigenvalues ​​of substations and towers according to the design scheme of the "National Grid Typical Design Manual", and then use the "least square method" to fit the eigenvalues ​​of substations and towers. For example, it can be identified by the tower shape, insulator string length, and wire information such as cat head pole tower, gate tower, wine glass tower, dry font tower, Crimean tower, upper font tower, single column tower, catenary tower, etc. Tower and voltage level; identify the substation and voltage level through the color, shape, size, floor plan, lightning rod, and transformer of the substation. The eigenvalues ​​are then made into templates.

[0052] Step 2. Use satellites or unmanned aerial vehicles to shoot the area where the geographic wiring diagram ...

Abstract

The invention discloses an aerial image identification based power grid geographical wiring diagram drawing method. The method comprises: selecting an eigenvalue of a substation or a tower, and performing fitting to make a template; intercepting an image frame from an aerial video; performing gray conversion on an image; performing histogram equalization reinforcement; obtaining a binaryzation effect picture; obtaining a denoising effect picture; obtaining a foreground picture only containing edge information; obtaining a graph outline of a suspected substation or tower; matching extracted edge contour information with a feature template of the substation or the tower, and performing marking when the matching is successful; connecting key points of the substation or the tower and performing drawing in a power grid geographical wiring diagram; and manually checking the power grid geographical wiring diagram. The method is high in efficiency, accurate in position and low in error rate, saves manpower and material resources, realizes automatic computer drawing, and greatly improves the efficiency and accuracy of drawing the power grid geographical wiring diagram.

Description

Technical field: [0001] The invention relates to a method for drawing a geographical wiring diagram of a power grid, in particular to a method for drawing a geographical wiring diagram of a power grid based on aerial image recognition. Background technique: [0002] The traditional geographic wiring diagram of the power grid is manually drawn by experienced grid planners.
