Abstract |
|
|
| In the process of high precision measure ,the error(positioning error) between geodesic data and actual data ,which are always caused by the deviation of the measured object placement ,will influence the analyzing of engineering model .According to the measuring mechanism of measured object , the mathematical model is created. Bisearch is used to chose simulation value of positioning error .Then positioning error is evaluated by fitting simulated and measured point cloud .This paper presents a practical program in error analysis and assessment ,which reveal the relationship between simulated data, restore image of point cloud and positioning error. |
