Abstract
:I n unm anne d ae rial ve hic le( U AV) object detecti on and identifica tion task,targets’ sizes vary
enor mous ly alon e with t he hei ght of the UAV. Some norma l o bjec t detection and identification algori thms
can only extra ct lim ited sm all objec t fea tures, which results in lo w detec tion per forma nce. R esearchers also
deve lop some deep neural ne tworks for s mall objects. But these mode ls always have small recept ive field
and lo se some large targets’ features . In this paper,a real-tim e o bject dete ctio n and id enti fication netwo rk
based on im proved Feature Pyram id Networ k ( FP N) mo dule is p ropo sed to promote the p erforman ce of
multi-s cale objects detection. Thi s imp roved FPN mo dule in
