[0051] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0052] The specific steps of applying the present invention to the identification of the cracks in the elastic strip are as follows:
[0053] S1: Image preprocessing process:
[0054] S1-1: Input the image to be recognized. Among them, the image to be recognized is a real image that is taken by an automatic control industrial camera and obtained in real time, such as figure 1 .
[0055] S1-2: Image denoising: A median filter of 3×3 template is adopted for the input image to keep the crack details and remove the scattered noise in the image.
[0056] S1-3: Image grayscale: The image captured by the camera is a 24-bit true color image and needs to be converted into a grayscale image for subsequent processing.
[0057] S1-4: Image enhancement: Gam...
