Abstract
For the problem on the deviation of actual measurement values between different network positions of visual measurement network system , so present the weighted data fusion algorithm . To distribute the weight coefficients according to the stability of eigenvector and fuse the coordinates , finally get the ultimate expression of fusion estimate. The experiment results present the maximum absolute tolerance of the fusion results is 0.039mm via the weighted data fusion algorithm, the maximum one via traditional data fusion algorithm of the center of point set is 0.056mm , Repeatedly measure 50 times , compared with the traditional algorithm, proposed weighted data fusion algorithm has much better precision and better stability.
