Embodiment Construction

[0026] The present invention will be further explained below in conjunction with the drawings and embodiments.

[0027] Cars with camera equipment will continuously collect a large number of high-definition images of wires and towers as they drive along the transmission line. The method of the present invention can classify the high-definition images of these wires and tower poles, which is convenient for manual or software to perform subsequent line fault detection and identification. Vehicle-mounted camera equipment includes visible light, infrared or ultraviolet equipment. In the known input image I, Width, Height, according to image 3 , This embodiment specifically describes the classification method as follows:

[0028] Step 1: Perform corner detection of multiple scales on the input image I, the number of scales is S, and the total number of detected corners is N.

[0029] When N is greater than a certain threshold T1, it is determined that the input image is a tower pole i...

Abstract

The invention relates to a power transmission line vehicle-mounted inspection image classification method. A plurality of potential safety hazards exist in the conventional manual inspection process, and the conventional manual inspection method is low in efficiency. The method comprises the following steps of: performing multi-dimension corner detection on input images; determining two types of images according to the number of corners; determining laplace-of-gaussian (LoG) transformation aiming at undetermined images to obtain wire masks; marking communication regions of the wire masks, and obtaining wire gray images according to the wire masks and the input images I; and finally, calculating the width of each wire in the vertical direction to obtain a histogram, and judging the other two types of images according to the histogram. By the method, a large number of inspection images can be classified and filtered, and the subsequent operation of detecting and recognizing failure manually or through software is simplified.

Description

Technical field [0001] The invention belongs to the technical field of intelligent inspection of power grid transmission lines, and relates to an image classification method for on-board inspection of transmission lines. Background technique [0002] Transmission lines have to traverse various complex geographical and meteorological environments, which brings great difficulties to the daily inspection work of transmission lines. Traditional manual inspections have many hidden dangers and low efficiency. In recent years, people have devoted themselves to the development of intelligent transmission line inspection methods.
