Abstract: In order to ensure the accuracy and credibility of pipeline detection, multiple detection techniques i.e. multi-
sensor are commonly used to detect the same part, but the detected data, miscellaneous and redundant, needs to be integrated
and processed. By using D-S (Dempster-Shafer) evidence theory, this paper sets up a process model of multi-sensor data
integration for pipeline, and presents the process of data integration. Based on detective credibility of various sensors to
different defects, detected data is integrated by using D-S evidence theory, and types of defect are determined according to
