03.12. A Global Feature-less Scan Registration Strategy Based on Spherical Structural Representation
Vortragender: Bo Sun
Zusammenfassung: The scan registration is the fundamental of several advanced 3D data processing techniques, and the majority of existing global registration methods are dependent on explicit features. This talk will introduce a global feature-less scan registration strategy based on Spherical structural representation via the Generalized Convolution Theorem. The 3D rotation is decoupled from 3D translation by computing the Spherical structural representation of the scan. The rotation is then estimated by the Generalized Convolution Theorem based on Spherical Fourier Transform. Finally, the translation is recovered by a classical method named Phase Only Matching Filter.No particular features in the input data are pre-requisite to our method.

10.12. Reasearch for manipulators on Chinas space station
Vortragender: Meng Chen
Abstract: Space station construction is the eternal topic of space and future exploration for human being. Facing the complex tasks in the construction and operational phases such as cabin assembly, module replacement, in-orbit maintenance and service, etc., space manipulator system is an alternative important tool to the astronauts engaged in repeated and heavy labor. Based on the author’s experience of research and development in space station robotic arms, this report systematically introduces the tasks, functions, critical technologies and solutions corresponding to manipulations of China’s Space Station. Moreover, the mathematical modeling, the simulation analysis and the experimental verification are displayed regarding to both physical prototypes and virtual prototyping. Finally, the report also introduces relative research works with respect to space docking mechanism, robotics of moon rover, dexterous manipulator and reconfigurable tetrahedral robot, as well as the future work.
