-== Automated sensor calibration toolkit (BA/MA)==+== Sprachgesteuertes Leitsystem (BA Thesis) ==
  
-Computer vision is an important part of autonomous robots. For robots the image sensors are the main source of information of the surrounding world. Each camera is different, even if they are from the same production line. For computer vision, especially for robots manipulating their environment, it is important that the parameters for the cameras in use are well known. The calibration of a camera is a time consuming task, and the result depends highly on the chosen setup and the accuracy of the operator.+Weiterentwicklung eines sprachgesteuerten Leitsystems zu gesuchten Produkten im Einzelhandel für Smartphones (Android) basierend auf Ankerpunkten und einer Anbindung an Wissensgraphen.

-== Simulation of a robots belief state to support perception(MA) ==+This is a knowledge representation topic including knowledge graphs. The idea is so link external Web-knowledge to an existing knowledge framework in order to include situational awareness so that a robot acting in a household environment can infer what an object is used for in a given situation.
  
-Create a simulation environment that represents the robots current belief state and can be updated frequently. Use off-screen rendering to investigate the affordances these objects possess, in order to support segmentation, detection and tracking of these in the real world. +A result would be that a spoon next to a bowl with cereal would be used for eating while a spoon on a stove next to a pot would be used for stirring.

-== Multi-expert segmentation of cluttered and occluded scenes ==+Contact: [[team:michaela_kümpel|Michaela Kümpel]]
  
-Objects in a human environment are usually found in challenging scenes. They can be stacked upon eachother, touching or occluding, can be found in drawers, cupboards, refrigerators and so on. A personal robot assistant in order to execute a task, needs to detect these objects and recognize them. In this thesis a multi-modal approach to interpreting cluttered scenes is going to be investigated, combining the results of multiple segmentation algorithms in order to come up with more reliable object hypotheses. 
  
-Requirements:  +== Development of Modules for Robot Perception and Game Engine Technology (Hiwi Job) ==

-  * strong background in 3D vision  +In our research group, we focus on the development of modern robots that can make use of the potential of game engines. One particular research direction, is the combination of computer vision with game engines.

 +  * Modelling of objects for the use in Unreal Engine 4. 
 +  * Creation of specific simulation aspects in Unreal Engine 4. For example the development of interactable objects. 
 +  * Software development to create Interfaces between ROS and Unreal Engine 4 (mainly C++)
