Evaluación de discontinuidades tipo grietas y fisuras en estructuras de hormigón empleando un analizador de vibraciones y procesamiento digital de imágenes 1

Characteristics in the Fourier spectrum of images associated with discontinuities such as cracks and fissures in concrete structures.

“…However, it was observed that other factors affect the MSE such as lighting, location, and brightness that are associated with the way the image is captured. In previous works [17], [18] already exists some treatment employing other techniques like mechanic vibrations-wavelet, and imaging processing with special techniques that shown good results, but nor does it quantify the magnitude of the damage; in our work it is possible quantify the differences between both patterns (cracks and fissures). Although these same factors (lighting, location, and brightness) generate a data variation that does not allow to associate specific characteristics with cracks or fissures, when performing the process several times with different images, the result indicates that in images that have a similar contrast, the error can be classified into a determined range.…”

“…Although the use of image processing is rare, there are advances that seek to develop an artificial vision system that serves as a tool capable of enhancing images, previously taken, and create a new one in which the discontinuities present in the image are more clearly evident. initial image [16] [17] As in turn, other systems aim to improve certain aspects of the images, to achieve highlighting specific details [18]. Thus, this document presents the development of an algorithm for the detection of discontinuities such as cracks and fissures, through the image processing technique applying the Fourier transform as an alternative for identification based on non-destructive tests of anomalies in structures of concrete.…”

“…For this, it's necessary to identify symptoms that indicate a possible failure in these assets, and specialized teams are required to carry out this work. In general, this equipment is expensive and not all companies have an economic leverage capable of supporting this type of investment [3].…”
