The World's Largest Dinosaur-Immortalised in Digital 3D


Sharing is Caring

The team at geospatial 3D mapping specialist GeoSLAM has claimed the unusual accolade of creating a digital twin of the world’s largest dinosaur.


Standing at 85ft and weighing a mammoth 65 tonnes, Drumheller’s T-Rex in Alberta, Canada was scanned using the handheld Zeb Horizon in just four minutes and 12 seconds.


Nothing could tricera-top the feat of scanning this popular attraction, which, at 151-feet long, is 4.5 times bigger than its fossilized counterpart. With 106 stairs to climb to reach its jaws, and a mouth that spans 60sq feet, the record-breaking attraction cost over $1million to construct in 2000.


The device’s ‘walk and scan’ method of data collection enabled GeoSLAM’s Matt Teppler to remain at an arm’s length and scan the structure on-the-go from the ground, accurately capturing the finer details of the design during his vacation.


The Zeb Horizon was chosen due to its ability to map objects within a range of 100-metres, capturing 300,000 points per second to an accuracy of 1-3cm while on the move. These features enabled Matt to collect the more complex, hard-to-reach details on the subject, due to its height, that traditional static scanners may not have been able to capture.
