Abstract

The invention discloses a crack parameter automatic extraction method and device and a storage device. The crack parameter automatic extraction method comprises the steps that of the crack parametersare automatically extracted, segmenting and extracting a crack image in a target picture based on a convolutional neural network, and correcting the crack image by utilizing a calibration pattern in the target picture to obtain a corrected crack image, or, correcting the target picture by using the calibration pattern in the target picture to obtain a corrected target picture, and segmenting and extracting a corrected crack image in the corrected target picture based on a convolutional neural network; and obtaining a crack size parameter of the corrected crack image under a real world coordinate through a scale factor under the real world coordinate corresponding to each pixel of the corrected crack image obtained through a calibration pattern in the target picture. By implementing the automatic crack parameter extraction method, the crack image is extracted and corrected by adopting a deep learning mode based on the convolutional neural network, and accurate and automatic extraction of the crack parameter data is realized.

Description

technical field [0001] The present application relates to the field of image extraction, in particular to a method, device and storage device for automatic extraction of crack parameters. Background technique [0002] Cracks may appear on bridges, tunnels, buildings, concrete pavements, and metal surfaces under the influence of factors such as stress, vibration, and temperature difference. The crack images can be processed to extract crack parameters. [0003] Due to the variety of environments where cracks exist, natural weather, light and pollution also limit the rendering effect of the image, resulting in the limitations of the existing technology, it is difficult to accurately segment the crack area in complex environments, so that the obtained Fracture parameters have limited precision. Contents of the invention [0004] The present application provides a fracture parameter automatic extraction method, device and storage device to solve the problem in the prior art t...
