A Development of Image Analysis Scheme For the Control of the Riser End

The objective of this study is to develop an image analysis scheme for the control of riser end, which is important for the riser connection with the seabed wellhead in offshore oil drilling and production. In the scheme, a single camera is used to get the image of the targets, an approach of 3D position recognition is used to get the 3D coordinate of targets from the images, and thereby the displacement of targets between different images can be obtained. In the study, the static and dynamic experiments on the image analysis scheme were carried out. This scheme can be applied to the re-entry operation of riser end, and its preliminary experiment was carried out.
