Abstract
System for controlling the loading or unloading a cable [2] or the like onto a drum [3], wherein the drum [3] has a known first rotation axis loading or unloading the cable, the system also comprises an imaging means [1] aimed at the cable [2] from a position at a distance from the drum rotation axis, the imaging means [1] being adapted to measure the direction of the cable [2] relative to the rotational axis of the drum. The imaging means can be constituted by a video camera.
Claims10
A system for controlling the loading or unloading a cable onto a drum, the system comprising:
- wherein the drum has a known first rotation axis loading or unloading the cable;
- an imaging means aimed at the cable from a position at a distance from the drum rotation axis;
- wherein the imaging means is adapted to measure the direction of the cable relative to the rotational axis of the drum;
- wherein the imaging means is adapted to provide a 3D image, thus being able to provide the direction of the cable in three dimensions;
- wherein the system is mounted on a platform being rotatable relative to a second axis being essentially perpendicular to the first axis;
- and
- wherein the system positions the platform to maintain a substantially perpendicular relation between the drum rotation axis and the cable direction.
A system for monitoring the position of cable relative to the deck of a vessel and controlling the loading or unloading the cable onto a drum, the system comprising:
- wherein the drum has a known first rotation axis loading or unloading the cable;
- an imaging means aimed at the cable from a position at a distance from the drum rotation axis;
- wherein the imaging means is adapted to measure the direction of the cable relative to the rotational axis of the drum;
- and
- wherein the imaging means comprises two cameras adapted to provide a 3D image, thus being able to measure x, y, and z coordinates of the cable relative to the drum rotation axis and a drum position and thus the direction of the cable in three dimensions.
