With the rapid development of civil aviation currently,the operation core business of airport onsite focuses on aircraft support,passenger service,and cargo handling.The systematization of existing passenger service and cargo handling systems is relatively mature,but aircraft support on the apron is mainly reliant on manual reporting of progress.This paper researches the key technologies of smart airport supervision system by utilizing next-generation information technology to design a set of technology scheme to maintain luggage and cargo security and convenient supervision for promoting automatic handling and intelligent improvement in civil aviation industry.Among this,it explores to improve the reliability of small target detection,so as to improve the detecting accuracy,balancing performance and computational power of small vehicles on the apron,and provides foundational technology support for airport business operation.Finally,it introduces the methods and effect of controlling cost and improving the target detection speed of in complex scenarios.
