Automatic identification method of bridge structure damage area based on digital image

Full size imageData processingBy analyzing the image features of bridge structure damaged area, the view angle of damaged area is modified. The noise of damaged image is removed, and the contour of damaged area is extracted. After the damage area view angle correction processing and the damage image denoising processing for the bridge structure surface image, the 8 images obtained are respectively as shown in Fig. Full size imageAfter the damage area contour extraction, the obtained damage area is shown in Fig. On the basis of obtained damage area image, through the automatic identification method of bridge structure damage area, the calculation of damage area scale, damage area proportion and damage area orientation is realized.
