Problems solved by technology

Image enhancement is not to enhance the information of the original image, but to enhance the discrimination of some information, and image enhancement will lose some information of the image
At present, there is no unified evaluation standard for image enhancement effect.

Embodiment Construction

[0049] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings. Under the windows operating system, VC++2010 is selected as the programming tool, and the defect detection is carried out on the cable image obtained by the equipment. This example uses a cable image acquired by the device as the detected object, and finally determines whether it has defects.

[0050] figure 1 It is a flowchart of the whole process of the present invention.

[0051] figure 2 It is a simple flowchart of the whole process of the present invention, and the first row of images corresponds to the result of the second row of technical processing. For example, the processing result of the "threshold segmentation" technique is the corresponding image above it, and the specific "threshold segmentation" technique is an improved maximum correlation threshold segmentation method adopted in the present invention.

Abstract

The present invention discloses an image detection method for cable rope surface defects, and aims to detect if cable rope surface images have defects. The method comprises the steps of performing graying processing on a cable rope surface image, carrying out enhancement processing on the grayed image by using an improved local grey-scale contrast method, carrying out a cutting processing on the enhanced image by using an improved maximum-correlation method, and, ultimately, performing defect determination according to the size of cut regions of the cut image. With adoption of the method, intelligent detection and judgment of cable rope surface defects can be realized, the workload and fatigue of manual visual inspection are reduced, the detection efficiency may be raised, and the method is safe and reliable.

Description

technical field [0001] The invention relates to an image detection method for surface defects of cables, belonging to the technical field of image processing. Background technique [0002] As one of the main stress-bearing components of bridges—cables, their surfaces will be damaged to varying degrees due to long-term exposure in the air. In the past, the surface of the cable was mostly inspected by manual observation, but manual inspection is very easy to cause fatigue, resulting in missed inspections and other problems. [0003] With the development of science and technology, image processing technology has become one of the research directions in many fields. With the advantages of fast speed, high precision, and never fatigue, it has achieved results in many industries. Using image processing technology to detect cable surface defects can not only improve the detection efficiency and reduce labor costs, but also lay the foundation for the objective standard of the cabl...
