| 摘要 |
<p>The present invention relates to a method for measurement of the thickness of any deposit of material on the inner wall of a pipeline (26) at least partly filled with a medium including hydrocarbons, the medium being for instance oil or natural gas, wherein the method comprises: projecting infrared light onto the inner wall (28) of the pipeline along a line (30) corresponding to the intersection between the inner wall of the pipeline and a cross-sectional plane of the pipeline; registering an image of the infrared light projected on the inner wall of the pipeline; and determining the thickness of any deposit of material on the inner wall of the pipeline based on the registered image.</p> |
