Abstract: The disclosure discloses a method for displaying a point of information of a map, a device, and a storage medium. The detailed implementation includes: obtaining a display position of a target point of information (POI) to be displayed; on a target electronic map displayed at a preset scale, determining a position relationship between the display position of the target POI and an influence region of each POI located in the target electronic map; and displaying information of the target POI at the display position of the target electronic map in response to the display position of the target POI being located outside the influence region of each POI in the target electronic map. With the technical solution of the disclosure, when the POI is displayed, the display efficiency and the intelligence degree are improved, the POI overlapping with its surrounding POIs is improved, and the overall display effect is ensured.

Abstract: Embodiments of the present disclosure disclose a method, apparatus, and device for fusing features applied to small target detection, and a storage medium, relate to the field of computer vision technology. A particular embodiment of the method for fusing features applied to small target detection comprises: acquiring feature maps output by convolutional layers in a Backbone network; performing convolution on the feature maps to obtain input feature maps of feature layers, the feature layers representing resolutions of the input feature maps; and fusing, based on densely connection feature pyramid network features, the input feature maps of each feature layer to obtain output feature maps of the feature layer. Since no additional convolutional layer is introduced for feature fusion, the detection performance for small targets may be enhanced without additional parameters, and the detection ability for small targets may be improved with computing resource constraints.
