This invention discloses a method, apparatus, and product for detecting small targets in drone aerial photography, relating to the field of computer vision, to improve the detection performance and parameter efficiency of small targets in complex background scenes. In the visual feature extraction process, the aerial image is downsampled hierarchically using a spatial-to-channel rearrangement approach to obtain multi-layered downsampled feature maps. A multi-branch convolutional structure is used to enhance the receptive field of each downsampled feature map, resulting in multi-scale visual features. In the text semantic enhancement process, at least one cue vector most relevant to the aerial image is selected from a cue vector library. The cue vector is semantically enhanced to obtain enhanced semantic features, which are then fused cross-modally with the multi-scale visual features. A detection head is then used to identify the target based on the cross-modal fused features. This invention improves the accuracy, robustness, and generalization ability of small target detection in complex environments.
