“…The concept consists of searching for the nearest pairs of points from two data sets and then minimizing the distance between them, in the iterative adjustment process (Eggert and Daylot, 2012). Such an approach can be performed with respect to ALS strip adjustments (Glira et al, 2015). One point cloud is considered as the reference cloud and the second cloud is matched to the first one.…”

“…Respective discrepancies are detected within standard quality control procedures (Ressl et al, 2008). If the deviations exceed acceptable limits, a typical LiDAR workflow also includes an adjustment to minimize the offsets between the strips (Glira et al, 2015a).…”

“…Thorough orientation of overlapping LiDAR strips and images, respectively, is a precondition for high-quality surface reconstruction. Sophisticated flight block orientation strategies and software implementations exist for both ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume IV-2/W4, 2017 ISPRS Geospatial Week 2017, 18-22 September 2017, Wuhan, China laser scans (Skaloud and Lichti, 2006;Glira et al, 2015a) and images (Kraus, 2007;Förstner and Wrobel, 2016). However, the simultaneous use of data from LiDAR and image matching implies a second level of relative orientation between scans and images which is important to consider when jointly using the point clouds of both acquisition techniques for deriving products (surface and terrain models, orthophoto mosaics, etc.).…”

“…To solve this shift error, we used the TLS point cloud to co-register the photogrammetric point cloud using the ICP algorithm and to extract the coordinates of some natural features employed as GCPs for combining direct geo-referencing with GCPs method. A version of the ICP algorithm tailored to topographic point clouds (Glira et al, 2015) was applied. The coregistration with the TLS point cloud minimized the orientation error of the photogrammetric model.…”
