However, to perform this integration both data-sets must be within a common reference frame. Although all lidar systems include a direct georeferencing procedure, the majority of low-cost photogrammetric systems do not have a facility for direct georeferencing of images even if the data-sets are captured simultaneously. In recent years, the high accuracy of the lidar data has enabled it to provide a source of photogrammetric control and thus to offer indirect georeferencing. This paper presents a methodology for the indirect georeferencing of digital SLR images using signalised lidar control points, together with the results obtained. The intensity image and raw lidar data-set were used to extract 3D coordinates of signalised control points. Two bundle adjustments of 21 images were performed. In the first case the coordinates of the control points were obtained by using GPS survey. In the second, they were extracted from a lidar data-set. The results obtained from these experiments confirm the feasibility of the proposed methodology Numéro de notice : A2011-078 Affiliation des auteurs : non IGN Thématique : IMAGERIE Nature : Article DOI : 10.1111/j.1477-9730.2011.00621.x Date de publication en ligne : 16/03/2011 En ligne : https://doi.org/10.1111/j.1477-9730.2011.00621.x Format de la ressource électronique : URL article Permalink : https://documentation.ensg.eu/index.php?lvl=notice_display&id=30859 [article]
