Abstract:

In this paper, we develop a measuring system for underground pipelines. There are some measuring system for underground pipelines. Most of them are inspection device by television camera. The measuring system is developed in order to measure the linearity of underground pipelines.The system does not use any laser emitter because of the inference from the envelopment. The principle of the system mechanism is to sum the relative locations. Firstly, we make the prototype of the measuring system based on the principle. Secondly, the theoretical error of the measuring system is derived from the error of the units which is the element of the system. Finally, we check the performance of the measuring system in the test field to measure a pipeline on the ground.
