英文摘要：

With the development of the industry such as aviation,automobile,shipbuilding,etc,the 3D profile measurement of the large-sized anomalistic free surface,body has been a kind of technology with applied outlook.The measuring proposal was put forward which could be used to 3D profile analyzing,manufacture checking and measuring.And the 3D profile measurement of the large-sized part could be done by using the digital measuring equipment-laser radar with high speed and high accuracy.Also,the measuring principle of laser radar was introduced.The process of the large-sized 3D profile measurement,the methods how to use the software SA（spatial analyzer）to get,the processing of data analysis were introduced.Experimental result shows that this measurement proposal can meet the measurement requirements of high accuracy,high efficiency and low labor intensity for 3D profile measurement of the large-sized part,and has the universal applicability to the large-sized 3D shape measurement.
