Image processing-based road crack recognition and repair trajectory planning approach

Aiming at the problem that the current pavement crack detection methods have less research on the repair trajectory planning for subsequent cracks, a raod crack detection and repair trajectory planning approach based on image processing is proposed. Firstly, the preprocessing method based on augmented nonlinear diffusion denoising is used to remove pretzel noise points; then, the FCM algorithm based on adaptive weighted spatial information is used to segment the crack features; then, the connectivity domain area filtering is used to remove the large noise points; finally, the coordinate point extraction and polynomial least squares are used to carry out the repair trajectory planning, and combined with the pavement crack detection and repair prototype simulation of the actual scene testing, to validate the reliability of the proposed approach.
