La présente invention concerne un véhicule aérien sans pilote (100) comprenant un fuselage (10), un bras (20), un dispositif d'alimentation (30) et un ensemble de photographie (40). Une extrémité du bras (20) est installée au niveau du fuselage (10). Le dispositif d'alimentation (30) est installé au niveau de l'autre extrémité du bras (20) à distance du fuselage (10) et est utilisé pour fournir de l'énergie de vol au véhicule aérien sans pilote (100). L'ensemble de photographie (40) est installé au niveau de l'autre extrémité du bras (20) à distance du fuselage (10) et est utilisé pour capturer des images. L'agencement ci-dessus permet d'empêcher qu'un appareil photo de l'ensemble de photographie (40) soit bloqué par un train d'atterrissage, une hélice et le bras (20) du véhicule aérien sans pilote, de sorte que le véhicule aérien sans pilote (100) puisse prendre des photographies panoramiques.
