Using a redundant coarsely calibrated vision system for 3d grasping
- 1999

Konferensbidrag (refereegranskat)abstract
- The influence of a redundant camera system for estimation of 3D object position and orientation in a manipulator´s workspace is analysed. The paper analyses the accuracy that can be achieved using a trinocular stereo system, that only has been qualiatively calibrated. By using stereo combined with a third camera a significant improvment in accuracy is achieved. An experimental system, which exploits colour and Hough transform for object pose estimation, is used for empirical assessment of accuracy in the context of object grasping.

Person following behaviour for a mobile robot
- 1999

Konferensbidrag (refereegranskat)abstract
- In this paper, a person following behaviour for a mobile robot is presented. The head of the person is located using skin colour detection. Then, a control loop is fed with the camera movements required to put the upper part of the person in the center of the image. The algorithm was tested in different rooms of a research lab. It performed well in all lightings except in direct sunlight. Since the background and lighting cannot be controlled, the vision algorithm must be robust to such changes. However, since the computing power is quite limited, the algorithm must have as low complexity as possible.
