Calculating 3D Point Clouds From Stereo Images Using MATLAB

This exercise is intended to help students to understand how to calculate a 3D point cloud from stereo images. We used a webcam, mounted on a four-wheeled LEGO vehicle on rails with a single large motor, controlled with MATLAB, to acquire pairs of stereo images and calculated the 3D point cloud of the opening of an agate druse.

New Master’s Degree Program at the University of Potsdam, Part 1

Today we announced the new English-language master’s degree program “Remote Sensing, geoInformation and Visualization” at the University of Potsdam. The program focuses on the gathering, processing, analysing, and presentation of geoscientific spatial data by using remote-sensing technologies and data-processing methods. The program uses models and theories to assess geoinformation, and then to prepare and communicate our findings with modern means of visualization.

Object Scanning with MATLAB using the LEGO Ultrasonic Sensor

This exercise is intended to help students to understand how to scan the absolute distance (in meters) of a 3D object from a ultrasonic sensor. The quality of the result, possible artefacts and sources of error are discussed in conjunction with the results of a previous exercise on the spatial resolution of the sensor.
