| Abstract: | Rotatory errors in measurement datas of pipeline measurement and mapping system are researched to determine the origin and mathematic model of these errors and how they affect precision of pipeline parameters, based on which, a method for reducing rotatory error is presented which consists of calibrating and compensation of parameters of the error model. A proving experiment in a section of oil pipeline is carried out to verify the validity of this method, which shows that the rotator error can be almost completely eliminated and the precision of pipeline parameter is effectively improved. |
