Experimental study on Error Modeling and compensation based on non-contact laser coordinate measuring machine

In order to improve the measurement accuracy of the non-contact laser coordinate measuring machine, both the error model of coordinate measuring machine and laser measurement are built based on blade measurement. The influence of the surface color and surface inclination angle of the measured object on the measurement errors are studied respectively through the experiment. The error curve shows the practicability and correctness of the error model of laser measurement. And then, the error compensation function is established based on error representation method. By the standard ball test, the measurement accuracy after compensation can reach to micron level and testifies the error compensation model is reasonable.
