3-1 Nonlinear Refinement of Camera Parameters using an Endoscopic Surgery Robot (2009)
Jochen Schmidt, Florian Vogt, Heinrich Niemann
We present an approach for nonlinear optimization of the parameters of an endoscopic camera mounted on a surgery robot. The goal is to generate a depth map for each image in order to enhance the...

Initial Experiments with a Mobile Robot on Cognitive Mapping (2008)
Wai K. Yeap, Chee K. Wong, Jochen Schmidt
Abstract. This paper shows how a mobile robot equipped with sonar sensors and an odometer is used to test ideas about cognitive mapping. The robot first explores an office environment and computes a...
Mapping and Localisation with Sparse Range Data Abstract (2008)
Jochen Schmidt, Chee K. Wong, Wai K. Yeap
We present an approach for indoor mapping and localisation with a mobile robot using sparse range data, without the need for solving the SLAM problem. The paper consists of two main parts. First, a...
Placing Arbitrary Objects in a Real Scene Using a Color Cube for Pose Estimation (2007)
Jochen Schmidt, Jochen Schmidt, Ingo Scholz, Ingo Scholz, Heinrich Niemann, Heinrich Niemann
Abstract We describe an Augmented Reality system using the corners of a color cube for camera calibration. In the augmented image the cube is replaced by a computer generated virtual object. The cube...
