Transformer substation patrol robot digital type instrument identification algorithm

Abstract

The invention discloses a transformer substation patrol robot digital type instrument identification algorithm. The transformer substation patrol robot digital type instrument identification algorithm comprises steps that a transformer substation patrol robot is used to acquire a device image, and is used for the pretreatment of the image; a digital area is located automatically; the inclination of the digital area is corrected; the segmentation operation of the digital area is executed by adopting a contour detection algorithm, and the digital positioning is executed according to a contour acquired after the segmentation operation, and then a single digital image is acquired; the digital images of the various forms on the scene of the transformer substation are acquired, and a digital identification training sample set is established, and an integrated classifier is formed; the trained integrated classifier is used for identification of a single digit, and a final identification result is acquired by sequencing the digits according to the coordinate of the above mentioned digit in the image. The transformer substation patrol robot digital type instrument identification algorithm is advantageous in that when surfaces of on-site instruments are dirty, and are inclined at a certain angle, a good identification result is still acquired, and the digital type instruments having certain defects are identified correctly, and in addition, the transformer substation patrol robot digital type instrument identification algorithm is suitable for the digits of the various forms in the transformer substation.

Description

technical field [0001] The invention relates to the technical field of substation digital instrument identification, in particular to a digital instrument identification algorithm for a substation inspection robot. Background technique [0002] Many substations in the power system are equipped with digital instruments, which are widely used because of their simple structure, intuitive, easy operation, low cost and low failure rate. A large amount of data needs to be recorded every day for such meters in the substation. At present, domestic instrument data is mainly recorded by human eyes, which has low precision, poor reliability, low efficiency and high labor intensity. With the pilot construction of smart substations and the development and popularization of inspection robots, the recording of instrument data has been improved towards automatic operation, but operators still need to participate in the verification and confirmation of instrument status images collected by ...

AI Technical Summary

Problems solved by technology

[0004] 1. At present, most of the digital recognition systems operate in an ideal lighting environment. Once they break away from this premise, the recognition effect is difficult to guarantee

[0005] 2. The feature matching and endpoint detection methods used in many schemes have high requirements for the segmentation of digital areas, and the robustness and scalability of such methods are greatly limited

[0006] 3. Most of the existing schemes deal with numbers in a single form, and cannot effectively deal with numbers in various forms in substations
