A method of producing multi-viewpoint panorama of a roadside is disclosed. The method comprises: - acquiring a set of laser scan samples obtained by at least one terrestrial based laser scanner mounted on a moving vehicle, wherein each sample is associated with location data and orientation data; - acquiring at least one image sequence, wherein each image sequence is obtained by means of a terrestrial based camera mounted on the moving vehicle, wherein each image of the at least one image sequences is associated with location and orientation data; - extracting a surface from the set of laser scan samples and determining the location of said surface in dependence of the location data associated with the laser scan samples; - producing a multi-viewpoint panorama for said surface from the at least one image sequence in dependence of the location of the surface and the location and orientation data associated with each of the images.

L'invention concerne un procédé de production d'un panorama à plusieurs points de vue d'un bord de route. Le procédé comprend : l'acquisition d'un ensemble d'échantillons de balayage laser obtenu par au moins un scanner laser terrestre monté sur un véhicule mobile, chaque échantillon étant associé à des données d'emplacement et des données d'orientation ; l'acquisition d'au moins une séquence d'image, chaque séquence d'image étant obtenue au moyen d'une caméra terrestre montée sur le véhicule mobile, chaque image du ou des séquences d'images étant associée à des données d'emplacement et des données d'orientation ; l'extraction d'une surface de l'ensemble d'échantillons de balayage laser et la détermination de l'emplacement de la surface en fonction des données d'emplacement associées aux échantillons de balayage laser ; la production d'un panorama à plusieurs points de vue pour la surface à partir du ou des séquences d'image en fonction de l'emplacement de la surface et des données d'emplacement et d'orientation associées à chacune des images.
