3Deling was selected to survey the Wieliczka Salt Mine in Poland, a UNESCO World Heritage Site. The Wieliczka salt mine reaches a depth of 1,073 feet and is over 178 miles long. The structure of the mine's chambers created a challenging environment in which to collect and document details with precision and accuracy. The data collected from the survey was used to produce three project deliverables: a 3D movie and virtual tour of the site; 2D floor and ceiling plans and sections; and an archive of point-cloud data for comparison with future surveys. The data collected via the survey will aid in detection of rock layer deformation and historic preservation of the site.
With data from advanced 3D laser scanners, and parallel camera paths, 3Deling created the stereo 3D movie and virtual tour by processing data through Bentley Pointools. High resolution orthoimages were processed in MicroStation and Bentley Pointools and used to create the 2D documentation of floor, ceiling plans, and sections. Initial baseline point-cloud data collected via the survey was archived for use in comparison to data collected in two to three years. This comparison will aid in detection of rock layer deformation and historic preservation of the site.
The interoperability of the Bentley tools and ability to process data in various file formats allowed for uninterrupted workflows during the collection of data and processing of project deliverables, reducing the time required to complete the project. From a broader perspective, the key outcome of the project will be its contribution to the conservation of this historic site.
All point-cloud data collected in the survey of the Wieliczka Salt Mine was processed using MicroStation and Bentley Pointools. Bentley Pointools was used to support the visualization, manipulation, animation, and editing of point-cloud data collected in the survey. MicroStation was used to create 2D and 3D models that will be used in conjunction with archived point-cloud data to detect rock layer deformation and help sustain the historic salt mine.
