Abstract
Disclosed is an intelligent recognition method for a time sequence image of a concrete dam defect. The method includes: extracting a feature sequence of the time sequence image containing the concrete dam defect; matching a located defect with a real defect by using an objective function; adding a loss term based on a tight sensing intersection-over-union to a loss function of a model so as to pay attention to integrity of a defect sequence and improve accuracy; and extracting a defect feature and recognizing a defect type after completing defect location. According to the present disclosure, the time sequence image of the concrete dam defect is detected effectively, so that a defect in a long image sequence can be located and the defect type can be recognized accurately.
