Novel approaches to solving really difficult problems, i.e. capturing large immovable objects, like the Tower of Pisa, in system to generate accurate 3D models in efficient fashion, never ceases to amaze, somethng CSIRO has done with a spring loaded portable scanner that acts like, in indirect fashion, a large bubble head doll.
Developed by the CSIRO, Australia's national science agency, the Zebedee technology is a handheld 3D mapping system incorporating a laser scanner that sways on a spring to capture millions of detailed measurements of a site as fast as an operator can walk through it. Specialised software then converts the system's laser data into a detailed 3D map.
While the tower's cramped stairs and complex architecture have prevented previous mapping technologies from capturing its interior, Zebedee has enabled the researchers to finally create the first comprehensive 3D map of the entire building.
Seen below is a partial rendering of the Tower. Pretty cool to say the least.
