Research On Multi-source Information Visualization For Inspection Of Pipelines

It's frequent for water supply network to explode and malfunction. These accidents cause water supply costs increasing and affect the safety of water supply network while these accidents cause damage to pipe foundation and other public utility above and below. In order to ensure the safty of the pipelines,it is necessary to master the condition of pipelines.So to research the multi-source information visualization for inspection is meaningful.As the development of NDT technology, different NDT methods based on different detective theories can detect diverse damage types. In order to describe pipe damage totally and exactly, pipe inner detective technology that is based on multi sensor becomes a key at home and abroad and how to merge and handle multi-source detecting information coming from multi sensor is the key point.According to the types and characteristics of damage, the article analyzes the method of collecting location, surface and depth features of damage area. To compare and analyze different methods of visualization, visualization algorithm which was based on RBF (Radial Basis Function) and double cubic B-spline function was put forward, and apply it to the process of information visualization modeling based on multi-source detecting information.To realize the visualized modeling and analysis of the pipelines...
