In recent years, object detection technology has become a hotspot in the research field of computer vision, which is widely used in UAV scene analysis, video surveillance, smart medical care and other fields. Nowadays, the detection of large and medium objects can't meet the actual needs. People put forward higher requirements for the performance of the algorithm. It is particularly important to improve the detection ability of the algorithm for small objects. However, small objects are difficult to detect because of the following reasons: poor resolution of small objects, dense distribution of tags, large scale difference between objects and susceptibility to background interference.
