The invention discloses a ground target detection method based on an adaptive hierarchical gradient
feature fusion strategy, and the method comprises the steps: obtaining a ground obstacle target
data set, constructing a ground target detection network, introducing a C2f-EIRM module into a
backbone network of the constructed ground target detection network, employing a hierarchical
feature fusion strategy for the C2f-EIRM module, and carrying out the
feature fusion of the C2f-EIRM module, introducing a plurality of branches to perform global
feature extraction; in the multi-
branch structure, an EIRM module is adopted to perform local
feature extraction, gradient operator
convolution is introduced into the EIRM module to construct an edge information module, the edge information module is combined with common
convolution in a self-adaptive adjustment mechanism mode, the
receptive field and edge information of the
feature extraction network are enhanced, and the model
detection performance is improved. According to the method, the target detection accuracy is improved, the efficient identification of the shielded
small target is realized, and the real-time performance and the accuracy of ground target detection of the low-altitude flying car are balanced at the same time.
