大型曲面的检测在现代工业测量中仍是一个尚未完全解决的问题，以激光测距器为基础的测量方法是现代工业测量中常用的一种方法，可以用来解决这个难题。该方法可在较大范围内达到较高的测量精度，属于非接触式测量，被测工件的状态不受约束。根据曲面特征建立合适的测量系统，通过激光测距获得被测曲面检测点的空间坐标，利用基于Matlab的曲面拟合软件获得曲面的表面特征三维图，采用基于单片机的自动控制系统实现自动化检测。所研制的装置具有准确性高、测量方便快捷、成本低、适应性强的优点，能够有效弥补国内便携式大型曲面测量装置空白，具有广阔的应用前景。

Detection of large-scale curved surface still remains unsettled in modern industrial measurement.The meas-uring method based on laser measurement scanner is commonly used in modern industrial measurement to solve this prob-lem.The measuring method can be used to reach high measuring precision within large scope,belonging to non-contact measurement,with the tested piece out of constraint.The proper measuring system is built based on the curved surface char-acteristics.The space coordinates for detecting points of the tested curved surface is gained via laser ranging.The surface 3D diagram is gained based on Matlab curved surface fitting software.Automatic detecting is realized via automatic control sys-tem based on single chip.The said device is provided with high precision,rapid measurement,low cost,and high adapta-tion,which can be effectively used as the portable large-scale curved surface measuring device,indicating extensive appli-cation prospect.
