Restitution semi-automatique en mode monoscopique sur un 
poste de photogrammétrie numérique 
Résumé 
Cet article porte sur l'extraction -semi-automatique d'objets au 
moyen de l'imagerie numérique en mode monoscopique. Parmi les 
sujets abordés, on trouve des questions relatives aux concepts, 
aux algorithmes et à la mise en application, les expériences 
effectuées, ainsi qu'une discussion sur les problèmes éprouvés et 
les solutions adoptées. Plus particulièrement, nous présentons 
l'algorithme et les résultats expérimentaux obtenus concernant 
l'extraction semi-automatique de réseaux routiers à partir 
d'images SPOT au moyen d'images transformées par ondelettes. En 
outre, dans le cas d'images à plus grande échelle et de divers 
types d'objets, nous comparons deux méthodes d'extraction d'objet 
que nous avons appliquées et mises à l'essai, soit les techniques 
du seuillage par moindres carrés et des modèles hypsométriques 
actifs (Snakes). Dans le premier cas, l'emplacement des courbes 
hypsométriques est déterminé avec précision gráce aux variations 
locales de l'intensité de gris. Dans le second, on obtient des 
résultats .significatifs .en. appliquant des contraintes de 
continuité globale. Finalement, nous proposons une nouvelle 
approche algorithmique de détection et d'enregistrement semi- 
automatiques du contour des objets qui combine les avantages des 
deux méthodes mentionnées ci-dessus. Le seuillage par moindres 
carrés constitue la base mathématique de cette approche, mais on 
applique également la continuité globale en introduisant des 
contraintes de formes en fonction du type d'objet, ce qui garantit 
des résultats cohérents au plan géométrique.
