Domestic oil pipeline is built exceeded the operation came back 20 years. Reliable and efficient means of transport in the oil transport place enough importance to be difficult to replace the pipeline was increased was positioned as a central infrastructure for industrial development. When the oil is transported in the pipeline is leaking due to some personal injury accident in long-distance pipelines unspecified period, depending on the scale accidents can bring up the material damage, economic instability, such as a disaster. Because petroleum products resulting from the performance of fire, explosion, causing soil pollution. You can check to prevent accidents long as ten years using technology was an important point. In particular oil thieves accidents resulting in artificial and spills is an indiscriminate crime is more dangerous. So this paper, we propose a vision system to see how to check for IT technology based pipeline accidents. Vision System Applications pipe inspection method is simpler than the existing pipe innovative technology more affordable health inspection techniques, can be used in a short time the test is the internationally accepted validated by conventional inspection intelligent PIG intellectuals agents and can be used immediately.
