AI Technical Summary
In existing technologies, the use of Class A or Class B evaluation methods in the error assessment process leads to inaccurate measurement results, affecting subsequent construction or safety monitoring conclusions.
By combining Type A and Type B evaluation methods, the initial measurement results are determined through observation data. The variance and covariance matrix of the observation matrix error is determined based on the observation error. The measurement uncertainty is determined according to the relationship between the observation error and the initial measurement result error, and finally, a more accurate measurement result is obtained.
Obtaining more accurate measurement results provides more precise guidance for subsequent construction, improving the reliability and accuracy of measurement data.
