Method and system for judging looseness degree of tower bolt based on laser image vibration measurement model

The invention discloses a method and system for judging the looseness degree of a tower bolt based on a laser image vibration measurement model, and the method comprises the following steps: S101, arranging a reflectivity layer on the surface of the tower bolt, and enabling the reflectivity layer to comprise two or more reflectivity regions with different reflectivity; s102, obtaining a pole and tower bolt laser signal and a pole and tower bolt reflectivity layer image signal based on the time sequence, and performing feature extraction processing; s103, based on a laser image vibration measurement model, tower bolt looseness and degree judgment processing is carried out on a feature extraction processing result; s104, generating a tower bolt looseness degree report based on the tower bolt looseness and degree judgment processing result; the tower bolt looseness and degree judgment processing is performed on the feature extraction processing result based on the laser image vibration measurement model, and whe
