Abstract

Des méthodes et des systèmes dimagerie douverture synthétique assistée par une imagerie par balayage à faisceau tridimensionnel, par exemple un lidar à balayage, sont décrits. Les méthodes peuvent comprendre lacquisition simultanée dune image douverture synthétique et dune image de balayage 3D dune région cible, la détermination dune carte de lélévation de la région cible à partir de limage de balayage 3D et le traitement de limage douverture synthétique en fonction de la carte de lélévation pour fournir ou améliorer les capacités dimagerie 3D dans limage douverture synthétique. Selon certains modes de réalisation, limage douverture synthétique est bidimensionnelle et la carte délévation est utilisée pour lorthorectifier. Selon dautres modes de réalisation, limage douverture synthétique est une image douverture synthétique 3D à emballage de phase résultant de la combinaison de deux images douverture synthétique 2D ou plus et la carte délévation est utilisée pour réaliser le déballage de phase.
