Zusammenfassung: | To provide a technique by which light-emitting markers can accurately be detected as a target based on light spots reflected on a captured image.SOLUTION: An unmanned aircraft 12 comprises an imaging unit 16. A guidance device 20 is a device for guiding the unmanned aircraft 12, comprising three or more light-emitting markers. The imaging unit 16 of the unmanned aircraft 12 captures an image of the outside of the unmanned aircraft 12. The unmanned aircraft 12 detects the positions of three or more light-emitting markers by excluding light spots mismatched with a predetermined light emission pattern from the candidates of three or more light-emitting markers, based on light spots reflected on the image captured by the imaging unit 16 and the light emission pattern of three or more light-emitting markers of the guidance device 20.SELECTED DRAWING: Figure 1
【課題】撮像画像に映る光点をもとに目標としての発光マーカーを精度よく検出する技術を提供する。【解決手段】無人航空機12は、撮像部16を備える。誘導装置20は、無人航空機12を誘導するための装置であって、3個以上の発光マーカーを備える。無人航空機12の撮像部16は、無人航空機12の外部を撮像する。無人航空機12は、撮像部16により撮像された画像に映る光点と、誘導装置20が備える3個以上の発光マーカーの予め定められた発光パターンとに基づいて、発光パターンに対して不整合な光点を、3個以上の発光マーカーの候補から除外することで3個以上の発光マーカーの位置を検出する。【選択図】図1 |
