摘要:Close range photogrammetry as applied for the as-built and as designed comparisons in the car industry has attracted serious attentions in recent years. This thesis reports in some details an off-line close range photogrammetric approach for the accurate measurement of the body of a Nissan Patrol car. The photographs are taken by the Zeiss UMK 10/1318U metric camera. In the first stage of the project, the body of the car is marked with the circular shape targets. The object coordinates of these targets were then determined with respect to an arbitrary coordinate system using geodetic surveying technique. In the subsequent stage a network was designed around the Nissan Patrol to be used for installing the cameras. The image coordinates of the target points were then measured by the SD2000 analytical plotter. The object coordinates of these points were calculated using collinearity condition equations combined with various self calibration strategies proposed by: Brown 1975, Brown 1976, Ebner 1976, Moniwa 1977 and El-Hakim 1977. The discrepancies between the coordinates of the points generated by the photogrammetric method and the coordinates of the same points produced by the geodetic approach, is taken as the accuracy criteria. The best results obtained for check points are 0.21 mm (rmse).
