The invention discloses a construction quality defect detection method and
system based on
image processing, and belongs to the technical field of material surface defect
nondestructive testing, and the method comprises the steps: obtaining original image data of a construction area and preset building
information model data, generating a material feature map and a reflection feature map, and carrying out the denoising and illumination compensation of the original image data, and acquiring enhanced image data, delimiting a key detection area to generate a dynamic
mask, executing defect identification by adopting a preset high-precision
convolution kernel to generate an initial defect
distribution diagram, and outputting a final defect detection result by combining defect correlation correction parameters generated by matching the initial defect
distribution diagram with the defect evolution
database. According to the method, a double-flow convolutional network is adopted to decouple material attributes and illumination interference, a dynamic
mask is combined to focus a high-
risk area, and a defect evolution
database is integrated to realize mechanical
simulation analysis, so that the defects in the
germination period can be accurately captured in a complex construction environment, the extension trend can be predicted, and the
engineering safety management and
control level can be remarkably improved.
