Concrete dam body crack identification method and device

The invention provides a concrete dam body crack identification method and device, and the method comprises the steps: obtaining a gray matrix of a first gray image of a to-be-identified concrete dam body crack, and building a seed point matrix based on the gray matrix; determining a first target pixel point in the first grayscale image based on the seed point matrix, and establishing at least one identification point matrix based on a pixel position, corresponding to the first target pixel point, in the first grayscale image; establishing a weight coefficient matrix based on the at least one identification point matrix; and finally, determining a crack region in the first grayscale image based on the grayscale matrix and the weight coefficient matrix. According to the invention, the problems of low detection efficiency and high detection cost in the existing crack detection technology can be solved. 本发明提供了一种混凝土坝体裂缝识别方法及装置，先获取待识别混凝土坝体裂缝的第一灰度图像的灰度矩阵，并基于灰度矩阵建立种子点矩阵；再基于种子点矩阵确定第一灰度图像中的第一目标像素点，并基于第一目标像素点对应在第一灰度图像中
