Methodology For Determination Of Space Control For 3D Reconstruction In Statscan Digital X-Ray Radiology Using Static Frame Model

摘要

The methodology was designed to employ two positioning techniques in order to determine the three-dimensional control space of target points on static metal frame model to be used as space control data in 3D reconstructions in Statscan digital X-Ray imaging. These techniques were digital close-range photogrammetry and precise theodolite positioning method. The space coordinates for the target points were determined 3D using both techniques. Point positioning accuracy 0.5mm in root mean square error of X, Y and Z space coordinates was achieved. The outcome of the comparison of the results obtained from both methods were of satisfactory accuracy hence further use of the control space data in Stastcan imaging and 3D reconstruction.
