摘要
To provide a quantitative evaluation method capable of quantitatively evaluating a damaged part having a planer spread on a concrete surface, a quantitative evaluation device, a quantitative evaluation system, and program.SOLUTION: A quantitative evaluation method of a damaged part on a concrete surface includes: a step of inputting a photographic image of a concrete surface including a damaged part having a planer spread into a computer and executing a brightness correction processing based on a predetermined brightness correction amount for the brightness at the time of the photographing; and a step of executing a wavelet conversion processing for the input image and creating a wavelet image having a wavelet coefficient for each pixel; a step of binarizing each pixel of the wavelet image using the wavelet coefficient which is a threshold value of the wavelet coefficient and creating a binarized image; a step of executing a pretreatment for the binarized image and creating a damaged part specifying image; and a step of calculating a quantitative value of the damaged part in the damage part specifying image.SELECTED DRAWING: Figure 4
