3D Laser Scanning Survey of process plant.
170 scanning set-ups and over 1200 photos for an impressive reverse engineering project.
Como Engineers Pty Ltd based in Perth, Australia, have asked Star Net to perform a detailed laser scanning survey of a Lead/Zinc process plant located in South West Ireland. The client has the ambitious plan to disassemble the facility and ship it over to Australia, completely refurbish and re assemble it in the new operational site.
Paramount for the successful outcome of the job was to get a foundation plan of all the structural steelwork and the positions of the various pieces of machinery within the building. In addition high resolution photography provided an invaluable tool for visualising the numbered steel members and the various materials.
As our lead site surveyor, Colin has reported:
“Each day we worked for approximately 10 or 11hrs to ensure we would complete the job on time. The machinery in the Mill building was all shut down in preparation for dismantling and shipping so there was no danger in that respect to our physical health/hearing and meant we had good access to all areas of the building.
While scanning we tried as best as possible to have 4 or 5 targets for each set up and have at least 3 overlapping into the next scan so each scan could be registered together accurately. After each scan we attached a camera with a fish eye lense to the scanner tripod. Using a Ninja bracket to position the camera in the same location as the scanner lense we took 6 wide angle photos set 60°apart to create a 360° image of the area just scanned. Back in the office, these photos were then overlapped to the scan data to generate the Truviews.
While the scanner was running we would always be looking forward to the next 2 or 3 scans so we could position our forward targets where they would be of most use. Concurrently we were also using topographical survey equipment to create a traverse around and through the building tying all the scanner targets together in a local grid.”
