Abstract: In this paper, a method of multimodal feature combination is proposed using images from an unmanned aerial vehicle (UAV) and encoded metadata. The applicability of the proposed approach to the tasks of UAV position regression and object classification in images with a minimal set of known metadata is considered. For regression, a mechanism for interpolating altitude values is introduced, which allows for a more accurate association between the visual representation of an image and its altitude, and provides greater stability to changes in altitude and camera rotation angles of the UAV. To regulate the contribution of textual modality, a method is used that ensures random ignoring of textual features and reduces overfitting on textual modality in addition to regularization by the feature alignment error and its coefficient of influence on the overall model error. The same approach is used for classification, with the comparison of several variants of textual templates. Experiments were conducted on the following datasets.

Keywords: multimodal neural networks, regression, classification, feature fusion, positioning, UAV.
