| Abstract: | this paper studies the free surface three-dimensional reconstruction technology.First of all,the use of a novel digital non-contact measuring equipment——Laser Tracker scans aircraft local model and get the point cloud data of the model,on the basis of this,the use of CATIA software’s reverse modeling function makes the surface reconstruction towards the point cloud data;finally,using alignment and data processing function of CATIA software makes relevant error analysis on the point cloud and reconstruction model.The experimental results show that the measuring method meets the error requirement and has a high practical value to the industrial application and production. |
