Systém pro snímání pohybu

Abstract

Motion capture technology is today one of the key elements for fast animation of virtual scenes and objects, another example of usage can be found in medicine or sport industry. The thesis describes the issues of motion capture, available technology, use cases and implementation issues.

The first part introduces the theory necessary to understand the principle of data processing from inertial units. The second part deals with description of architecture, construction and implementation of the system. Inertial sensors (IMUs), which include an accelerometer, a gyroscope, and a compass to record orientation, are used to record motion. These sensors are mounted on the object being recorded and the data is read by the central unit that collects and sends them for further processing. Several techniques and complementary filters are used to calculate the orientation to refine and smooth the orientation. Against the use of gyroscope and accelerometer units, this solution provides a solution for Yaw drift that suffers from simpler design.
