[0002] With the rapid development of highway construction in my country, the mileage of highways has been increasing. As one of the basic industries of my country's national economy, highways have driven the smooth development of related industries. However, with the passage of time and the increase in vehicles, the highway pavement has been damaged to varying degrees, which has reduced the quality of the pavement and shortened the service life of the highway. This requires strengthening the detection of pavement damage to ensure the quality of the pavement.

[0003] The existing crack detection methods for bridge pavement mainly include image recognition method, ultrasonic detection method and optical detection method. The image recognition method uses a camera to shoot the ground and then sends the shooting data to the server, and uses the powerful processing power of the server to identify and judge the received data. Therefore, when shooting the bridge pavement, the real situation of the road surface directly affects the accuracy of the detection. Therefore, in order to make the photos consistent with the actual situation, usually before shooting, the staff needs to clean the debris on the road surface to ensure the accuracy of the shooting. However, this cleaning method not only requires a large number of staff to cooperate, increasing the detection cost, but also takes a long time to clean, affecting the detection efficiency.
