Abstract

L'invention concerne un procédé de traitement de mise au point, un terminal, un dispositif infrarouge, un système, un véhicule aérien sans pilote et un support. Le procédé consiste à : recevoir un ensemble d'images cibles envoyé par un dispositif infrarouge, l'ensemble d'images cibles comprenant de multiples images, et les multiples images étant générées par le dispositif infrarouge lorsqu'un utilisateur ajuste la distance de mise au point du dispositif infrarouge ; et analyser des images dans l'ensemble d'images cibles pour générer une courbe de netteté de mise au point, la courbe de netteté de mise au point étant utilisée par un utilisateur pour ajuster la distance de mise au point du dispositif infrarouge selon la courbe de netteté de mise au point. Au moyen des modes de réalisation, l'effet de focalisation est optimisé et la précision de mise au point est améliorée.
