A method of calibrating line structured laser measurement systems on numerical controlled machine is introduced. The angle of laser sheet can be calculated directly by the principle of triangle measurement and the coordinate precision of the machine itself. The structure parameters of the camera can be got by least square fitting algorithm. A laser center index is provided for precision enhancement. The measured coordinates can be modified through multiplying the modification factors that can be checked up in the laser center index. A neural network model of fitting the modification factors is also introduced to improve the interpolation precision. This method is especially suitable for engineering applications.
