St. Georges Terrace Kangaroos
One of the nicest spots in Perth CBD is the area between St. Georges Terrace and Barrack Street - the Stirling Gardens. Between 1996 and 2000 three artists - Anne Neil, Joan Walsh-Smith, Charles Smith - have build magnificient bronze Kangaroos that amaze kids and grown ups.
By using our newest 3D Scanning technology we surveyed one of these statues with the aim of creating several products from this dataset:
-
A virtual model by combining geometrical and photographies
-
Visualisations: Films and stills
The first step was to scan the statue from different perspectives by using our 3D Laser Scanner to cover as much as possible of the surface. Eight different views were captured and assembled into one point based model.
Single perspective of a point cloud (the result of a measurement)
Therefore the single patches were imported into a software that uses least squares adjustement to find an optimal alignment of the point clouds.
Assembling of different perspectives into one model
Visualisation of the single patches in different colours
The final model consists of 52.9 million points which makes it probably the best surveyed Roo in the country
Finally the points are used to create a closed surface representation. Therefore small triangles are calculated by using parameter estimation techniques (non uniform rational b-spline fitting).
