“…In reverse engineering, we collected the large number of point cloud data form surface of the model with certain methods of measurement,then the data was processed and reconstruction to curve and surface,and finally physical CAD model is obtained [1].In this process,there is much error in the reconstruction of the model,so it is necessary to analyze the accuracy of the surface [2]. Generally,we carry out accuracy assessment for CAD model reconstructed,there are main three problems to be solved:the factors affecting the the accuracy of the surface,the error value of the model surface reconstructed,and whether the surface accuracy is qualified [3].…”

The precision analysis of surface model is one of the key technologies in reverse engineering.Analyzed the error sources of surface accuracy in reverse engineering,proposed an evaluation indicators of the surface accuracy,which are whether the reconstructed model is qualified.Taking rearview mirror for example,compared with the reconstructed model and the original point cloud data by three-dimensional and two-dimensional methods in Geomagic Quality software,obtained the deviation value of the whole model and three different directions,the results show that the error of the most data points is in the range of permissible,which is less than the pre-set error;take the reconstructed surface data and the original point cloud data for comparison, more than 94% of the total data points is in the range of permissible, prove that the fitting surface accuracy is qualified.
