| titleOfInvention | It is a kind of based on machine vision from berthing job parameter computing device |
| abstract | The present invention relates to a kind of based on machine vision from berthing job parameter computing device, including：Construction unit pre-establishes hull coordinate system, image coordinate system, camera coordinate system and mark source coordinate system；Measuring unit, stem reference point is at a distance from ship stern reference point and camera installation site is at a distance from stem reference point for measurement；Acquiring unit obtains the camera course angle and pitch angle that imaging moment is identified on camera opposite bank；Computing unit calculates mark source coordinate system to the translation vector of camera coordinate system；And it calculates hull coordinate system and identifies the Eulerian angles of source coordinate system；And it is calculated from berthing job parameter according to above-mentioned parameter；Judging unit judges whether to terminate, from berthing operation, until from berthing operation to terminate according to from berthing job parameter.The present invention ensures that mark can be imaged in limited camera field range on the bank, relaxed the constraint to camera visual field, ship-to-shore position orientation relation, improved from berthing parameter calculation precision；Calculating process is simple, and operand is small. |
