Embodiment Construction

[0031] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0032] figure 1 It is a scheme flowchart of the present invention, and concrete steps are as follows:

[0033] Step 1. The substation inspection robot collects equipment images, uses Gaussian smoothing filter to preprocess the image returned by the substation robot inspection background, suppresses the noise in the image, and uses homomorphic filtering to reduce the influence of uneven illumination on the image.

[0034] Step 2, automatically locate the position of the digital instrument equipment. The determination of the position of the digital instrument is the premise of identifying the digital instrument. First, we use the rectangle detection algorithm to obtain several rectangular areas in the image.

[0035] In step 3, a training sample set is composed of digital area samples and non-digital area samples, and the pictures in the training set are manu...

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 ...
