Popis: Asian hornets are considered a pest because of their dangerousness and their impact on the ecosystem. Detecting nests of this species is a difficult task, as they are found in the trees, hidden in the leaves. Our goal is to carry out this detection from images acquired by a drone. We propose in this work a new method, based on the advantages of visible spectrum and FLIR images. We compare two models of state-of-the-art neural networks (YOLO and Mask-RCNN) for this task. The results are presented from the two separate image sets, then by combining the network responses. To do this, a third dataset (for ensemble model) was built by simulating a FLIR acquisition simultaneous with the acquisition in the visible spectrum. Preliminary results show that the best strategy is to use Mask-RCNN on the ensemble model (detection rate of 93%). A discussion on the relevant information present in the images and on taking into account of this information by the networks is also proposed.
