[0026] On the basis of the basic data enhancement operation on the dam crack image data, the real crack image data of the dam is used as input, and an image generator (DGM) based on the deep convolution generation counter network is used to generate the dam crack image. The structure is like figure 1 As shown, an image discriminator (DDM) based on a deep convolution generation confrontation network is used to judge the quality of the image generated by the DGM. The discriminator structure is as follows fi...

Abstract

The invention discloses a dam crack image data enhancement method based on a deep convolution generative adversarial network, and the method comprises the steps: (1), taking dam real crack image dataas the input, and generating a dam crack image; (2) judging the dam crack image generated in the step (1). According to the invention, on the basis of basic data enhancement operation, an image generator (DGM) based on a deep convolution generative adversarial network is used to generate the crack image, an image discriminator (DDM) based on a deep convolution generative adversarial network is used for discriminating the quality of a generated image, and a new dam crack sample data set is generated according to original small sample dam crack data, thereby meeting the requirements for the typeand data size of a training sample in the dam crack image recognition technology.

Description

Technical field [0001] The invention belongs to the technical field of engineering safety monitoring, and particularly relates to a method for enhancing dam crack image data based on a deep convolution generation counter network. Background technique [0002] During long-term operation, hydraulic structures are affected by various factors such as light, water flow impact, and temperature changes, and are prone to functional degradation and surface cracks. These problems may affect the normal operation of the dam. Dam crack detection is an important way to discover hidden dangers of dam safety in time. Traditional dam crack image recognition mainly relies on human vision, but the efficiency and accuracy of crack detection and recognition will decrease during long-term work. With the development of digital image processing technology, the traditional manual method of detecting image cracks has been gradually replaced by machine vision-based crack detection methods, becoming one of...
