AI Technical Summary

Technical Problem

In the detection of water retention performance of gypsum mortar, when using the PTICS density clustering algorithm, due to the inaccurate initial reach distance threshold, some normal areas on the solidified sample of gypsum mortar to be tested are mistakenly divided into rough areas, which makes the detection results more common Large error.

Method used

By obtaining the difference in reachable distance between the sample point and the surrounding sample point and the distance between the sample point and the cluster cluster, calculate the reachable distance data sensitivity of the sample point, obtain the change consistency of each reachable distance, and according to this Calculate the optimal neighbor-reach distance threshold and cluster all rough areas on the gypsum mortar cured sample to be detected to accurately obtain the normal area.

Benefits of technology

The accuracy of clustering results is improved, the accuracy of the water retention performance test results of the gypsum mortar cured samples is ensured, and errors are reduced.
