A marine laser scanning project typically follows the steps shown below:
1. Formulation of the scanning plan
When a scan request is received, the first step is to have a good idea of the purpose and scope of the scan according to the customer. If it is not possible to visit the area to be scanned, plans of the work area are requested. Based on the information available, a scan plan will be formulated.
2. On-board scan
A work team will travel to the area that needs to be scanned to make the captures according to the work plan. It will ensure that the captures of each scan overlap enough without too many blind spots. For this, the scanning equipment will be placed in the appropriate position so that the same area is illuminated with the other scans from a different point of view.
3. Refinement of the point cloud
Once the team has performed enough scans to cover the designated area, a preliminary point cloud of the work zone can be obtained. This point cloud will be "refined", aligning the different scans to best fit, eliminate "noise", and so on.
4. Modeling and engineering
One misconception regarding 3D scanning is that the scanner does all the work and that what comes out of the scanner is a definitive model that shows everything you need. The point cloud is the raw data that needs to be designed into a viable 3D model. In many cases, the actual scanning activity is only a small part of the total project scope.
Depending on the conversation with the client's requirements, it is possible to convert the point cloud into a viable and adaptable 3D model.
5. Manipulation of the As built model
Once the point cloud has been designed in a building model, manipulations can be performed on it such as:
• Incorporate ballast water systems (BWTS)
• Incorporate the installation of the exhaust filter (EGCS)
• Make any kind of change in the environment.
• Damage repair
