Advancing 3D laser scanning
With our latest purchase of the newest, ultra-high speed 3D laser scanner, the Leica ScanStation P40, we wanted to explore how this technology has advanced and if it could bring yet higher quality to our production. Under real-world conditions, we directly compared it side-by-side to our current HDS7000 scanner by scanning steel beams in the prefabrication stages.
To ensure a direct comparison between the scanners, the settings were equaled with a scan density of 6.3 millimeters point spacing at 10 metres distance from the scanner and set for 3.5 minute scans. We scanned and analysed the edge of the deck plating.
A main weakness in laser scanning in general is the noise at edges, known as mixed pixels. Mixed pixel noise was considerably lowered with the ScanStation P40 over the HDS7000.
There was also a better representation in geometry and contrast of the deckbeam, webplate beam and the deployed High Definition Survey targets with the new
ScanStation P40.
At MEYER WERFT, where measurement quality and efficiency are critically important for cruise ship building, 3D laser scanning has proven to be increasingly beneficial in our daily activities. Our test results on the ScanStation P40 point to an even better future for this technology.
