New research project 3D-MAPP: 3D-MicroMapping of Big 3D Geo-Datasets in the Web
Wednesday, 30 March 2016 08:25


The research project 3D-MAPP located at the University of Heidelberg develops a web-based methodology to obtain digital geodata via the combination of data analysis by human and machine. Through a quick and easy-to-use 3D Web visualization users are able - in a few seconds - to solve 3D micro mapping tasks, which can hardly or even not be solved by automatic algorithms. Based on an extensive user study the idea of 3D-MAPP shall be evaluated empirically.

Visualization of time series data with Processing
Wednesday, 08 February 2012 18:44

The following example shows a visualization of time series data (lightnings of the austrian state Salzburg in 2003) using the Processing library for Java. The screenshot shows an applet which visualizes the state Salzburg as well as its environment and some actually recorded lightnings from Mai 2003. The position of the lightning impacts are converted from real world to screen coordinates to "hit" the respective point on the plane. A time slider on top of the application can be used to navigate within the data.



We are yet very comfortable with the result but certainly have many things in mind to enhance the visualization. Stay tuned!

Autodesk Photofly
Wednesday, 19 October 2011 14:05

Today I tested Autodesk Photofly, a lab-project to automatically create 3d scenes out of a set of photos. I wasn't very confident before my colleague Bernd and I started but I wanted to build my own opionon about the system. My car was choosen to be the test object and I have to admit that I'm very impressed about the result.

Due to the bad weather conditions we have to hurry taking the pictures and only made 38 pictures of my car. After waiting for the pre-processing to finish, I was able to define the animation path for the 3d video (1080p!) of my car.



Here are some screenshots out of the video:





If one look at the roof and the front window one may assume a recent traffic accident, but this is certainly due to the poor amount of photos taken from the roof of the car.

All in all the result is very impressive and if we put a bit more time in taking more pictures I am pretty sure that the result would be much better.


Conclusion: Autodesk Photofly - thumbs-up!
