Visualization for a Multi-Sensor Data Analysis

This paper describes our efforts in creating the software in order to analyze the multi-sensor data for gas transmission pipeline inspection. The amount of data is usually considerable because the hardware system that consists of multiple heterogeneous sensors records multi-sensor values for long-distance inspection. It imposes a heavy burden on the operators who should sieve the huge and complex data, detect features of the pipeline and decide a feature as a significant defect. In our system, the virtual 3D pipeline helps the user to examine the inside of pipeline intuitively by navigating according to the realistic pipeline trajectory. We mapped the geographical data of the pipeline and heterogeneous sensor data on the virtual 3D pipeline. Moreover, our system offer the various feature detail views to help the users rapid and precise decision. Users can switch the navigation mode and the feature detail mode easily. Consequently, the virtual pipeline plays a role as an intuitive interaction metaphor for pipeline inspection
