3D scanning for marine projects
Whether you are looking for a fast, accurate way of measuring and recreating a boat hull to enable design changes or for remanufacture, the most reliable method of data capture is 3D optical measurement.
Physical Digital® uses the industry-leading GOM 3D optical scanning systems to capture and measure the data from boat hulls for a variety of purposes. The data achieved by this high accuracy optical measurement can be used to carry out quality inspection or to create 2D drawings or 3D CAD models for optimisation or remanufacture.
Tight deadline? Here’s how to speed up your project…
• Physical Digital provides quick and accurate data capture from boat hulls using GOM ATOS and TRITOP systems to help meet your tight deadlines.
• High resolution measurement and inspection with verified accuracy ensures you receive the most accurate data for your projects.
• We can create high quality CAD model through reverse engineering to carry out quality inspection reports and assist with your design projects and remanufacturing.
How we capture the high accuracy measurement data
Physical Digital’s highly-trained engineers have wide experience of carrying out 3D scanning on boat hulls, using the following steps and systems:
The GOM TRITOP system acts as a framework for the scans gained from the 3D scanner. The photogrammetry system works by calculating the centre of the circular reference points using several images captured with a high resolution DSLR camera.
Calibrated carbon fibre scale bars are used to define a relative scale for the photogrammetry measurement. The point cloud generated from the TRITOP system is used to precisely locate the scanning system around the hull to avoid any further deviation associated with adding multiple measurements.
Photogrammetry helps provide an extra framework to obtain the greatest amount of accurate data from your objects.
The ATOS scanning systems use a blue light projector and stereoscopic cameras to capture high resolution surface data of the boat hull. GOM ATOS systems can recalibrate to various measuring volumes depending on the size of the object being measured. This allows the data capture of large boats in a short space of time.
Once the data has been captured, the inspection back to CAD is quickly achieved using ATOS Professional software.
How long will it take?:
The amount of time it takes to capture a boat hull depends on the overall size of the object and the resolution required to capture the features. Many projects can be completed over one working day but more time may be required for particularly large or complex craft.
What format do I receive the data in?:
The output from the scanning process is a high-resolution polygon mesh as an STL file. This can be aligned and inspected against existing CAD geometry using the GOM Inspect software. From this, our engineers can create an inspection report focusing on overall deviation or the geometry of particular features and how they compare to the designed model.
The alternative is to recreate the scanned file but with perfect geometry in a CAD package. This will ensure that the model has symmetry along the centreline and that any geometric features are recreated exactly. This service can be completed by our in-house design engineers who are fully trained in Siemens NX.
I want to show my non-technical manager the results:
Using GOM inspection software, Physical Digital provides printable, easy to interpret 2D reports, using industry-specific or customer-specific templates. One of the many advantages of the GOM optical measurement system is that it offers image mapping technology to provide real-life visualisation of quality inspection results. This feature provides fast data interpretation, giving the real-life context of the results, which enables non-technical personnel to understand the reports.
Sounds great – how do I get in touch?
Our specialist team is able to 3D scan, inspect and reverse engineer boat hulls with a high level of accuracy. These same techniques can be used to ensure YOUR project is completed quickly and accurately to save you time to market.
