Foreign body monitoring system for airport road surface

The invention belongs to the technical field of optical detection, and discloses a foreign body monitoring system for an airport road surface. Scanning equipment of the foreign body monitoring system is connected with an industrial control computer through a data transmission network to carry out data transmission; the industrial control computer is connected with a master control server; the master control server is connected with a display device; and the master control server is connected with the scanning equipment through a bus way. The scanning equipment receives the control signal of the master control server, collects the image of the airport road surface and sends the image to the industrial control computer; the industrial control computer carries out real-time picture analysis and foreign body recognition treatment and sends information to the master control server; the master control server gives an alarm and sends information that a foreign body exists to the display device; and the display device receives the information that the foreign body exists transmitted by the master control server and displays the information of the foreign body. Working processes are participated, controlled or completed by relevant control and recognition software. The foreign body monitoring system can work day and night; the foreign body which is 5 millimeters can be automatically detected and recognized; the manual confirmation can be carried out simultaneously; the reliability of the alarm is improved; and the detection precision is high.
