What’s the point?! Point characterization explained
What are the characteristics of a point and how can we calculate them? This is a short introduction to point characterization.
Algorithm
Is it a car? Is it a tree? Machine learning to the rescue!
Imagine this, a city is documented by millions of points acquired by an airborne laser scanner. Now, in order to make sense in all these points, we need to go one by one and classify it – does it belong to a tree? A building? A road? Here, we used a deep neural network to do the work for us!
Algorithm
The secrets of an important point
Each point cloud is composed of millions of points, how would we know which are the most important?
Application
3D models to preserve a graffiti-scape in Vienna
Graffiti upset, please, provoke. However, they are also short-lived, often exist only several hours or days. If not documented, part of this unique cultural heritage will vanish forever. The INDIGO project tries to change this by building an online 3D platform to analyse present and past graffiti-scapes.
Application
Home Between The Tides – a 3D Look at Intertidal Habitats
Point clouds to characterize the intertidal habitat, where extraordinary creatures live between tides.
Application
Point Clouds Shed Light on the Evolution of the Dead Sea Sinkholes
Continuous monitoring by terrestrial and airborne laser scans allows to quantify the evolution process of the Dead Sea sinkholes and serves as a basis to further understand their dynamics.
Application
The Hidden Story of the Desert Standing Stones as Told by Point Clouds
The secrets a 3D laser scanner revealed in the documentation of 5th Century BC standing stones cult sites in the Israeli desert
Application
Point Clouds to Track the Planning of 5000 Year Old Desert Kites
Using the 3D point-clouds acquired by terrestrial laser scanner we follow the plan and construction of the desert kites, large game traps from 5000 years ago.
