When it comes to 3D data, we don’t leave room for error.
The key to successful and accurate dimensional analysis by 3D scanning begins with an uncompromised campaign of 3D data collection. We will not downscale the images or 3D data to make them easier to handle or convert the geometry to a ‘mesh’ to make it look more complete. We will diligently apply the capture techniques, photographic skills, and analysis software to reduce dataset errors to the smallest possible degree.
To minimise errors during dimensional analysis, it is important to understand the basis of such errors. These can occur during data collection, but also during the analysis if the correct methods are not used. As such, we use raw points clouds during analysis, alongside the very latest in point cloud analysis software.
Digital 3D datasets provide unhindered measurement capabilities by enabling analysis of complex geometries in ways that traditional tools like callipers cannot replicate. This allows measurement of freeform surfaces between any two points, comparative analysis vs CAD (or previous 3D datasets) and material loss calculations.
There are very few reasons to convert your hard-worked 3D point cloud into a mesh, and dimensional analysis is not one of them. Meshing of datasets creates false measurement points, and more importantly ‘papers over the cracks’ in terms of revealing critical information. A gap in point cloud data is very important and the reasons for the gap need to be understood. Oftentimes it can represent a crack which the lighting system hasn’t illuminated, leading to a gap in the points. If processed as a mesh however, the conversion process will simply ‘bridge’ the data gap and offer the impression that no crack exists.
In the subsea sector, no dimensional analysis is more crucial or safety-critical than that applied to the monitoring of mooring links. With designed corrosion rates of around 0.4mm per year, only the most accurate methods can provide a measurement tolerance that can track such degradation year after year and provide assured dimensions to your Certifying Authority.
Our experience in the underwater sector allows us to work seamlessly alongside your engineering teams and intimately understand your measurement needs. This helps you to eliminate doubt and ensure your project meets the demands of your project team and stakeholders.
