Abstract

An anchor-free object detection method based on ultraviolet image includes: obtaining a ground-truth label of object detection, two label boxes corresponding to the two labels; obtaining a masked label based on the two labels and the two label boxes in the train set, and performing a same enhancement processing on the train set and the masked label; constructing an anchor-free object detection model including an encoding part, a decoding part and a detection head part including three detection heads, namely two anchor-free detection heads and one anchor-free dual-head detection head, and the dual-head of the anchor-free box dual-head detection head is an anchor-free detection head and an auxiliary detection head, respectively; training the model based on the enhanced train set and the enhanced masked label; and inputting the ultraviolet image data to be detected into the final anchor-free object detection model, to obtain an object detection result.
