horizontal reference point Explanation: Myślę że choć odpowiedź Franka idzie dobrym tropem, z dalszego opisu wynika jednoznacznie, że chodzi o punkt odniesienia w płaszczyźnie poziomej, w przeciwieństwie do: "Obiekt kontrolny wysokościowy" - stąd moja alternatywa |

control reference point Explanation: Punkt przecięcia dwóch linii dachów służy jako control reference point. -------------------------------------------------- Note added at 11 hrs (2016-01-16 01:33:19 GMT) -------------------------------------------------- To differentiate from vertical control reference points, one has more precisely, ground control reference points Ground control reference points can be used to determine the absolute phase ambiguity http://163.32.57.16/earth/files/literature/14022.0254_LiDAR_... ccccccccccccccccccccc Additionally, some areas, primarily the channel of MVD03 (Figure 3.13), could not be modeled in large chunks or pieced together as a result of a low camera vantage point and widely spaced ground control reference points. https://dlib.bc.edu/islandora/object/bc-ir:102320/datastream... ccccccccccccccccccccc LIDAR), platform stability (aerial versus orbital), ground control corrections, and ... does not contain an identifiable set of ground control reference points, ... http://link.springer.com/chapter/10.1007/1-4020-3968-9_8#pag... cccccccccccccccccccccccccccc The geographical information system database (ArcView GIS) was used to perform the calibration of coordinates of the image data. After the completion of coordinate the calibration via ten ground control reference points (GCP; Table 1 and Fig. 1), a overlay analysis was carried out to evaluate the RMS errors of image data (Table 2). http://tao.cgu.org.tw/pdf/v213p543.pdf cccccccccccccccccccccccccc -------------------------------------------------- Note added at 11 hrs (2016-01-16 01:38:30 GMT) -------------------------------------------------- point-based reference control from lidar data for subsequent use in aerial triangulation. Kwak et al., 2006 and Mitishita et al., 2008, for example, used centroids of rectangular building roofs as a single control point in the aerial triangulation process http://www.sciencedirect.com/science/article/pii/S0924271614... cccccccccc The presented work covers methods for the detection of remaining discrepancies in overlapping LiDAR strips with main focus on the development of a new precise 3D measurement technique based on intersecting roof ridge lines and roof planes which are automatically reconstructed from the LiDAR point clouds in overlapping strips. For the generation of 2D and 3D control points, several roof ridge lines were determined photogrammetrically by measuring sample roof ridge points in digitized aerial images with nearly the same acquisition date as the LiDAR data. http://www.isprs.org/proceedings/XXXVIII/1_4_7-W5/paper/Rent... |
