Group of researchers of Australia made the most detailed internal 3D map of the known falling Tower of Pisa by means of the advanced manual scanner.

Researchers of CSIRO, Municipal scientific agency of Australia, developed the Zebedee technology, system of manual creation of 3D maps on the basis of the laser scanner attached to a spring to embody million detailed measurements of a surface with speed of movement of the operator of the device. Later the special program converts the data found by the laser scanner, in the detailed 3D map.

The device allowed researchers to rise by the Tower of Pisa and to go down with the detailed, complex 3D map of all construction, despite close ladders of a tower and difficult architecture.

Zebedee consists of the compact LiDAR scanner with bigger range of capture in 30 m, also ordinary industrial inertial measuring MEMS device (IIU) attached by the ordinary spring mechanism.

When the user keeps the device during movement in space, the scanner is weakened balances on a spring, thus, reaching rotary motions which change corresponding 2D the plane of scanning of LiDAR in 3D a field.

By means of the software package, it is possible precisely and to calculate 6 degrees of freedom of a trajectory of the sensor continuously on laser and inertial measurements in real time, measurements can be designed on a coordinate axis to make 3D a grid.

«In 20 minutes of work with Zebedee we could end scanning of all interior of a structure. It allowed us to make a unique comprehensive and exact 3D map of structure and an internal design of a tower, including pretty details at steps and a stone», – doctor Johnathan Roberts, the leading researcher of the program of Department of computing informatics in CSIRO said.

«This development absolutely is suitable for display of a cultural heritage, on what a lot of time and forces quite often leaves. From time to time the group of researchers can be necessary from several days to several weeks to make the detailed and high-quality card of object which we received in some hours».

This detailed picture not simply beautiful, it will also essentially affect preservation of a cultural heritage.

«Our detailed picture of the Tower of Pisa can play once very important role at reconstruction if the tower needs that in a consequence of influence of external destructive forces or earthquakes. Having detailed 3D the cultural value most known in the world, it can be used in order that people who cannot physically behold it, could look at the digital version, receive bigger understanding of history and architecture», – said Franco Tekchia, the assistant professor of PERCRO, Perceptual Robotics laboratory.

Vpribavok, the scanner can be used for efficiency and efficiency growth, for example, helping mining companies it is better to plan the acts, or militias during investigation, way of scanning of places of crimes.

The technology now can be got in a look 3D the ZEB1 scanner through the British technology of laser creation of 3D maps.
