Abstract

La présente invention ‌a‌ ‌pour‌ ‌objet‌ d'évaluer la progression par jour de travail au niveau d'un chantier. À cet effet, l'invention porte sur un système d'évaluation de progression de chantier qui acquiert l'image d'un chantier 50 du jour de travail imagé de manière aérienne par un moyen d'imagerie 42 monté dans un drone 40 (étape S1). Un serveur 10 traite l'image de chantier acquise en données tridimensionnelles 16B. Pendant ce temps, une différence entre les données tridimensionnelles 16B et un dessin de conception 16C du chantier 50 est extraite (étape S3), et la progression du jour de travail est estimée conformément à la différence extraite. Des instructions de travail relatives aux jours suivants sont données à des travailleurs sur chantier 60 selon l'évaluation (étape S4).
