Optimized Motion Capture System for Full Body Human Motion Capturing Case Study of Educational Institution and Small Animation Production

摘要

Motion capture system or MOCAP is a set of devices used for capturing moving objects. In addition to had used in the scientific community, Medical, Engineering, MOCAP is currently being used extensively in film and animation industry to create realistic movement of the characters and cartoons. A popular MOCAP system used to capture the movement is Optical Motion Capture, called Optical MOCAP that is able to apply a variety of object motions. Nowadays, the price of MOCAP system is high. And if the user uses full system of MOCAP to capture the movement of actor, some incorrect movement data occurred. This reason, the user needs to take a lot of effort to correct the movement data. With the high price and used effort, making institution or manufacturer difficult for decision-making provides the MOCAP to use. This research has the idea to study the adjustment device of MOCAP system that has minimal system and proper motions for basic of full body human movement, including of walking, running and jumping. By adjusting the number of cameras, the number of reflect markers, the placement of the camera. To capture the movement of the display area 10 square meters with review data movement and the movement of the cartoon show in real-time motions. The results showed that the number of cameras 4-6 to capture the movements of the actors in the area of 10 square meters and a height of 2.5 meters with digital camera, named Eagle Digital, placed at different. Use the least 29 points of reflection markers placed on actor, gait walking, running and jumping. There are both important moving markers and referencing markers. The importance points must placed the marker are actor head and a long of the spine. The results of this study will work with the amount of data movement is reduced. As well as to decide to use MOCAP equipment to suit the job they need.
