Abstract

One or more embodiments of the invention provide a tower signboard structured data obtaining method and device and electronic equipment. The obtaining method comprises the steps of obtaining an original image; inputting the original image into a pre-trained target detection model to obtain a tower signboard image, identification information in the tower signboard image and a content sideline in the tower signboard image; obtaining the type of the tower signboard image according to the position relationship between the identification information; calculating the geometric transformation precision of the tower signboard image according to the content side boundary; and outputting the identification information, the type and the geometric transformation precision of the tower signboard. According to the embodiment of the invention, through the pre-trained target detection method, the signboard can be positioned and identified at the same time, the identification steps are simplified, andthe identification efficiency of the signboard structured data is effectively improved.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of structural data identification of tower signage, and in particular, to a method, device, and electronic device for obtaining structured data of tower signage. Background technique [0002] At present, the technology of using drone aerial photography to inspect transmission lines is becoming more and more mature. During the inspection process of drones, by taking pictures of the signs on the towers and using algorithms for automatic identification, the transmission lines can be accurately positioned. [0003] In the prior art, the main steps of the automatic recognition algorithm for the tower identification plate are: for any picture, first locate all the quadrilateral frames in the picture, and for each quadrilateral frame in the picture, identify whether there is identification information in the quadrilateral frame , if there is, then the quadrilateral frame is an identif...
