| Abstract: | The center coordinates of the multi-target optimization approach is the key to improving the accuracy of the digital measurement system and intelligent image system.Combining the rough set theory and the K-means algorithm,this paper proposed a multi-target optimization approach with the rough set theory.The optimized coordinate with a multi-target center was obtained by the noise removal,multi-target region recognition and the target center calculation.Finally,we validated the method’s performance on a simulation bridge.The results showed that the accuracy was 74.5%,the correlated coefficient was 0.290,indicating that this method satisfactorily met the requirement of accuracy and robustness. |
